Snapping: transform snap in editmode couldn't snap to data in the same mesh.

added. Tweak still doesn't work for the loopcut op, but it didn't before, so at least we're advancing.

Since bli_threads.h now includes pthreads directly, we need to had instructions in SConscripts everywhere for proper include path.
Frankly, I feel like this should be done in a global manner and not in a per lib fashion, but that is for another day.
This commit also fixes more missing properties

* Unified scene wide gravity (currently in scene buttons)
instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group
setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
- "Point" is most like the old effectors and uses the
effector location as the effector point.
- "Plane" uses the closest point on effectors local xy-plane
as the effector point.
- "Surface" uses the closest point on an effector object's
surface as the effector point.
- "Every Point" uses every point in a mesh effector object
as an effector point.
- The falloff is calculated from this point, so for example
with "surface" shape and "use only negative z axis" it's
possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer
just spherical.
* New effector parameter "flow", which makes the effector act as
surrounding air velocity, so the resulting force is
proportional to the velocity difference of the point and "air
velocity". For example a wind field with flow=1.0 results in
proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random
flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force
(note. the z-axis is the surface normal in the case of
effector shape "surface")
* New "force field" submenu in add menu, which adds an empty
with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector
system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for
particles, softbody & cloth, since their final effect depends on many external
factors, like for example the surface area of the effected faces.
Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through
DAG_id_flush_update(..).
Known issues
* Curve guides don't yet have all ui buttons in place, but they
should work none the less.
* Hair dynamics don't yet respect force fields.
Other changes
* Particle emission defaults now to frames 1-200 with life of 50
frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to
free pidlists after use :).

* Rendering twice or more could crash layer/pass buttons.
* Compositing would crash while drawing the image.
* Rendering animations could also crash drawing the image.
* Compositing could crash
* Starting to rendering while preview render / compo was
still running could crash.
* Exiting while rendering an animation would not abort the
renderer properly, making Blender seemingly freeze.
* Fixes theoretically possible issue with setting malloc
lock with nested threads.
* Drawing previews inside nodes could crash when those nodes
were being rendered at the same time.
There's more crashes, manipulating the scene data or undo can
still crash, this commit only focuses on making sure the image
buffer and render result access is thread safe.
Implementation:
* Rather than assuming the render result does not get freed
during render, which seems to be quite difficult to do given
that e.g. the compositor is allowed to change the size of
the buffer or output different passes, the render result is
now protected with a read/write mutex.
* The read/write mutex allows multiple readers (and pixel
writers) at the same time, but only allows one writer to
manipulate the data structure.
* Added BKE_image_acquire_ibuf/BKE_image_release_ibuf to access
images being rendered, cases where this is not needed (most
code) can still use BKE_image_get_ibuf.
* The job manager now allows only one rendering job at the same
time, rather than the G.rendering check which was not reliable.

After code review and experimentation, this commit makes some changes to the way that volumes are shaded. Previously, there were problems with the 'scattering' component, in that it wasn't physically correct - it didn't conserve energy and was just acting as a brightness multiplier. This has been changed to be more correct, so that as the light is scattered out of the volume, there is less remaining to penetrate through.
Since this behaviour is very similar to absorption but more useful, absorption has been removed and has been replaced by a 'transmission colour' - controlling the colour of light penetrating through the volume after it has been scattered/absorbed. As well as this, there's now 'reflection', a non-physically correct RGB multiplier for out-scattered light. This is handy for tweaking the overall colour of the volume, without having to worry about wavelength dependent absorption, and its effects on transmitted light. Now at least, even though there is the ability to tweak things non-physically, volume shading is physically based by default, and has a better combination of correctness and ease of use.
There's more detailed information and example images here:
http://wiki.blender.org/index.php/User:Broken/VolumeRendering
Also did some tweaks/optimisation:
* Removed shading step size (was a bit annoying, if it comes back, it will be in a different form)
* Removed phase function options, now just one asymmetry slider controls the range between back-scattering, isotropic scattering, and forward scattering. (note, more extreme values gives artifacts with light cache, will fix...)
* Disabled the extra 'bounce lights' from the preview render for volumes, speeds updates significantly
* Enabled voxeldata texture in preview render
* Fixed volume shadows (they were too dark, fixed by avoiding using the shadfac/AddAlphaLight stuff)
More revisions to come later...

and scons)

Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.

Seems to have been a copy+paste error (code for Vertex Color adding was pasted in place of texture paint). Restored the code from an earlier revision (from another file).

Create new orientation is now Ctrl-Alt-Space (Alt-Space is select orientation and the old ctrl-shift-c is taken by add constraints).
New orientation panel in 3d view sidebar (nkey) has operator buttons for select, create and delete. Eventually, this should become a list.
Note that orientation operators are missing notifiers to properly redraw the 3d view and its header properly.

blocking the user when opening a menu. Material and texture buttons now
display these icons in the list. Also fixes #19387, icon and full preview
render at the same time would crash.
I'm not really convinced this is thread-safe, but on the other hand also
not sure regular preview render is really thread-safe yet.

* Move mesh API functions to mesh_data.c, would like to keep
RNA layer fairly thin, any non-trivial functions shoud be
in their modules.
* Replace mesh.create_copy by generic id.copy.
* Fix #19250: Mesh.add_geometry() in editmode fails silently,
now gives an error.

* The code to draw only visible items was not working, giving slow
performance with many files (bug #19469).
* Fix detailed list display on non-windows, would give overlapping text.
* Fix folders with many files not displaying all items, changed short to
int in various places, was overflowing.
* Recreate layout on area resizes, file view gets out of sync otherwise.
* Workaround for v2d height not being correct with image display due to
scrollers.
* Fix view2d code to compute minimum scroller size, this would make the
scroller go outside of its bounds.

This (biggish) commit generalises the rotation modes functionality added for Bones, allowing Objects to use the various Euler Rotation orders, Axis-Angle, and Quaternion rotation representations.
I've also cleaned up the nomenclature of the rotation-related settings so that the naming styles are more consistent with each other. Unfortunately, this will break all files involving object or bone rotation animation made in 2.5 versions (2.4x will still get correctly converted).
General Notes:
* By default, Objects still default to using Eulers, while Bones will use Quaternions by default still.
* I've fixed all areas that I'm currently aware of to work with these changes. However, there are probably a few places where I've missed a few changes (i.e. auto-keyframing will need attention later).
* Removed the old "IPO-Keys" stuff from Transform code. I'm unlikely to restore this in the near future, and trying to fix that to include support for this commit would have been too much work.

slide operator in the last operator panel, and uncommented a line in the remove doubles op that was making it not work (and tweaked the rna limits a bit there, too).
|
|
* Some Code and Whitespace Cleanup.
|
|
* Added missing RNA wrapping for Scene -> AnimData
* Fixed bug (with temp-fix) where sequence strips with no names couldn't be animated properly. Currently, this will just use the index of the strip, although that is likely to be mutable (adding/removing strips will change it).
* Removed some old unused code from action.c

single function.
|
|
Main Feature:
* It is now possible to choose which AnimData block is the 'active' one for editing, and/or select them too. AnimData blocks are generally the dark blue and lighter-blue expanders (i.e. Scene, Object, Camera, Lamp, Curve, Armature, etc.)
* Objects are no longer selected/deselected when AKEY is used to toggle selection of channels. This was getting a bit annoying.
* Following on from selection of AnimData blocks, it is now possible to select/make active an AnimData block in the animation editors, and change the active action for that block via the 'Animation Data' panel in NLA Editor's properties region.
--> Be aware that user-counts are not totally handled correctly there yet, so some funky behaviour might be seen...
--> It is possible to assign a new action, or to assign an existing one, allowing to switch between actions as in the past with Actions/IPO Editors...
Other tweaks:
* Some code tweaks towards making the 'Euler Filter' feature for Graph Editor working sometime soon
* Added some backend code for snapping the values of keyframes to a single value. Still need to work out some UI for it though.
* Shuffled the code for ACT_OT_new() around, and removed the poll() callback so that it worked in NLA too.
* Fixed some more notifier bugs with deleting bones and a few other editmode operations for Armatures.

once with the Ctrl-Shift-M hotkey.
* All the selected F-Curves will get the same type of F-Modifier added.
* The button in the properties region will still only added the F-Modifier to the active F-Curve though
* For now, there must be an active F-Curve in either case, otherwise the poll() callback fails.
|
|
* Deselect all now selects/deselects F-Curves too
* Tangents of unselected F-Curves now draw 'faded' like the curves they belong to. This experimental change is quite subtle, but can be made stronger still if people want.
* Cleaned up some old comments in the code too...

from these operators.
|
|
Drivers can now be copied/pasted for single properties, allowing drivers set up on one property to be added to a few other properties relatively easily.
Also, added description strings for the other driver-button operators.
|
|
* Loopcut is now just Ctrl-R.
The preview will be activated when you do this, and you can just click to confirm as in 2.4x and also like when this was activated from the toolshelf. This is less error prone than having to click at the same time as picking the loop as with the previous hotkey.
* Knife is now just: hold k-key and lmb click+drag to draw a cut line and cut the mesh.
This is more direct than the (rather arcane) Ctrl-X-LMB-drag, and is quite similar to what's done for Grease Pencil now.

* #19459: Shape Keys not Animateable
Shape Keys were missing the appropriate 'path' callbacks.
* #19458: 3D Viewport doesn't refresh when adding new bone in editmode (using Shift-A)
The 'wrong' notifier was being sent. Currently, Armature EditMode only responds to NC_OBJECT|ND_TRANSFORM, which isn't strictly that correct for all cases.
* Alignment code for constraints headers (i.e. enable/disable lumped with the delete constraint button) was causing the delete button to not work anymore. Removed the offending code (it shouldn't have been there to start off with).
* When object's don't have their own AnimData (i.e. if you only animate the values of some shapekeys), a space is no longer left beside the object's name for a visibility toggle in the Graph Editor.

With mouse events event->val started as 0/1 for press/release but later the tweak function made LMB and RMB zero value into KM_RELEASE, somehow MMB didnt get used by the tweak function so was left at 0 and the modal keymap function failed when comparing MMB Mouse ups.

* Loading old (2.4x) files with keyframes now inits them properly so that keyframes are tagged as normal keyframes not breakdowns
* TrackTo consraint was flagged wrongly for adding it with a target. This meant that the target didn't get set when using the Ctrl-Shift-C hotkey.

* Removed panel docking. "It is too easy to do by accident when reordering panels, is very hard to control and use, and has no real benefit."
* Scoll bars have minimum size now, so that the 'thumb' doesn't disappear in long lists.

- access with the F key, Ctrl+Alt+F in editmode, View->Navigation menu
- camera, perspective & 4split (perspective view only)
- uses modal keymap, (same as 2.4x).
- bugfix since 2.4x, when flying upside down, turning left/right was inverted.
- bugfix for "Align Camera To View", was using deprecated v3d->ofs rather then rv3d->ofs, fixed for NDof fly too. checked v3d->ofs is only used in readfile.c
Todo
- Warping the cursor removed in 2.5, no way to place the cursor in the middle of the view.
- Adding keyframes while in flymode to record the path is missing.
- Not getting MMB mouse release events (used for pan). need to look into why.

* Vertex Groups list now has a more normal length (2 rows by default)
* Copy vertex groups button now has an icon
* Pose Sliding tools now allow events which it doesn't process to pass through (i.e. zooming the view now works, and also moving around using the numpad works too)
