Improve the quality of current grease pencil strokes adding a new dynamic smooth and subdivision. The level of smooth and subdivide can be adjusted using UI parameters. These options are disabled by default in order to keep the grease pencil stroke compatible with any existing add-on.
Both parameters are defined at layer level.

The "UI_OT_eyedropper_id" operator only actually works in the 3D view,
so change the tooltip to match that

Unexpectedly found out what was going wrong here. If a file was saved with a filebrowser open, we searched for the channel region in the wrong list (see 'ListBase *regionbase = (sl == sa->spacedata.first) ? &sa->regionbase : &sl->regionbase;').
Minor annoyance is that I had to move the loookup to the 2.77.1 version patch now.

Seems to be a division by zero error.
Should be safe for an upcoming 'a' release.

Own mistake in 802bb422671
Apparently we only store one preview region for all views, didn't know that (makes sense though).

When linking a rotation property to a non-rotation property (going in either
direction - i.e. rot -> normal, normal -> rot), the driver expression will
now be set so that the new drivers behave as expected (i.e. you get the values
you see, instead of "weird" values that seem several orders of magnitude off).
This may not be that great for everyone (i.e. the rare users out there who
actually like to look at their rotations in radians), but they usually know
what they're doing anyway, so this will be easy to correct.
|
|
Although it isn't currently exposed, this allows for the old behaviour,
where an "empty" driver was added (without any target assigned yet).
For this reason, it's also referred to as the "Manual" mode.
There are also some attempts at improving the tooltips + names for the
other modes (again, not shown anywhere yet)

Work around what appears to be a compiler bug.

Looks like some distro still provide llvm-3.4-devel, while no more clang-3.4.
Since clang depends on llvm of same version, check clang only should ensure
us we also have matvhing llvm... *sigh*

render is done.
Follow same logic in `psys_render_restore` as in `psys_render_set` - if hair and
display percentage is not 100%, we have to recompute particles...
With regular 'emitter' particles just hiding some is fine (though using random here
will not give a precise proportion...).

readfile.c would increment object usercount in three places, where it should not.

"blank") names

This commit brings some long requested improvements to the workflow for setting up
drivers, which should make it easier and faster to set up new drivers in a more
interactive fashion.
The new workflow is as follows:
1) Hover over the property (e.g. "Lamp Energy" or "Y Location") or properties ("Rotation")
you wish to add drivers to. We'll refer to this as the "destination"
2) Ctrl-D to active the new "Add Drivers" eyedropper
3) Click on the property you want to use as the source/target. The property under the
mouse will be used to drive the property you invoked Ctrl-D on.
For example, to drive the X, Y, and Z location of the Cube using the Y Location of the Lamp,
hover over any of the X/Y/Z location buttons, hit Ctrl-D, then click on the Y-Location
button of the Lamp object. Drivers will be added to the X, Y, and Z Location properties
of the Cube; each driver will have a single variable, which uses the Y-Location Transform
Channel of the Lamp.
Tips:
- Transform properties will automatically create "Transform Channel" driver variables.
Everything else will use "Single Property" ones
- Due to the way that Blender's UI Context works, you'll need two Properties Panel instances
open (and to have pinned one of the two to show the properties for the unselected
object). It's slightly clunky, but necessary for implementing a workflow like this,
as the UI cannot be manipulated while using eyedroppers to pick data.
- The eyedropper operator implemented here actually has three modes of operation.
1) The "1-N" (one to many) mode is the default used for Ctrl-D, and "Add Driver to All"
in the RMB Menu. This is the behaviour described above.
2) There's also a "1-1" (one to one) mode that is used for the "Add Single Driver" in the
RMB Menu.
3) Finally, there's the "N-N" mode (many to many), which isn't currently exposed.
The point of this is to allow mapping XYZ to XYZ elementwise (i.e. direct copying)
which is useful for things like locations, rotations, scaling, and colours.
Implementation Notes:
- The bulk of the driver adding logic is in editors/animation/drivers.c, where most of
the Driver UI operators and tools are defined
- The property eyedropper code is in interface_eyedropper.c along with all the other
eyedroppers (even though they don't share much actual code in common). However, this
turns out to be necessary, as we can't get access to many of the low-level buttons API's
otherwise.
Todo:
- It may be necessary to restore a way to access the old behaviour (i.e. "manual setup")
in case it is not practical to immediately pick a property.
- Other things to investigate here include extra hotkeys (e.g. Ctrl-Shift-D for Add Single?),
and to expose the N-N mode.
- Other things we could try include interactively applying scaling factors, picking
multiple targets (e.g. for location difference and rotation difference drivers),
and/or other ways of using these property picking methods.

previously just DKEY)
Just using DKEY for this was resulting in too many drivers being accidentally created
by users drawing using Grease Pencil. This change also works better with the following
workflow changes to the driver setup process.

Until we officially support llvm3.5 or more, only allow for 3.4 llvm packages,
and build own stuff otherwise...

Disclaimer: this is tentative fix, seems to be working but you never know with particles.
If issue arise, we'll just revert this commit and hide 'use modifier stack' option
for grid distribution instead.
This commit also try to make choice of which dm to use during distribution more generic
(deduplication of code), again hopping not to break anything. :P

Steps to reproduce were:
* Open default video editing layout
* Drag down or click '+' icon in upper right corner of sequencer view
* A preview region appears, even though the view type is not set to sequencer-preview split mode
Another bug that has been there since ages :/ Reported by @Blendify via IRC, thanks!

This seems quite useful for the development, so you don't need to wait
all the kernels to be re-compiled when working on a new feature, which
speeds up re-iteration.
Marked as an advanced option, so if it doesn't work so well in practice
it's safe to revert anyway.

Quite straightforward, main trick is happening in path_source_replace_includes().

This commit makes it so casting subsurface rays will totally ignore all
the BVH nodes and primitives which do not belong to a current object,
making it much simpler traversal code and reduces number of intersection
tests.

search menu
Steps to reproduce were:
* Go to edit mode, select geometry
* Spacebar -> search for bevel OP
* Activate *using enter key*
* Immediately stops when releasing enter key
To fix we simply make sure the initial release event is ignored. For mouse events that wasn't an issue since activating an element is done on key release in menus. An alternative fix would be to do the same for enter key, but that's more risky. Also, checking event value is highly recommended anyway.

This reverts commit fe0ca82b232dcab29030c4a20b8bd1b033d1d346.
This is a design issue, needs more thinking, for now just revert back to old behavior.
|

While it was indirectly disabled already, it's handy to use the config
as template and enable certain features. In case of Cycles enabling it
would also enable OSL which is not very expected.

This commit:
* Fixes bad handling of 'stop iteration' (by adding a status flag, so that we can actually
stop in helper functions too, and jumping to a finalize label instead of raw return, to
allow propper clean up).
* Adds optional recursion into 'ID tree' - callback can also decide to exclude current id_pp
from recursion. Note that this implies 'readonly', modifying IDs while recursing is not
something we want to support!
* Changes callback signature/expected behavior: return behavior is now handled through flags,
and 'parent' ID of id_pp is also passed (since it may not always be root id anymore).

Don't calculate sine twice, store this in a variable instead.
Perhaps compilers can optimize this out, but helping them a but wouldn't hurt.

This patch adds support for coloring point density textures based on several mesh vertex attributes.
* Vertex Color: Use a vertex color layer for coloring the point density texture
* Vertex Weight: Use a weights from a vertex group as intensity values. (for Blender Render engine the additional color band is used)
* Vertex Normals: Use object-space vertex normals as RGB values.
The vertex color source enum is stored separately from the particle color source, to avoid invalid values when switching.
Note that vertex colors are technically "corner colors" (MLoop), so each vertex can have as many colors as faces it is part of.
For the purpose of point density the mloop colors are simply averaged, which is physically plausible because corners can be viewed
as multiple points in the same location.

F-Curves easier
Now, when trying to insert a keyframe on a driven property (using IKEY, or with
autokeying enabled), the keyframes will get created on the Driver's F-Curve
(instead of creating a new FCurve that goes into the active action, but will never
do anything). Furthermore, the x-value of the new keyframe will be the current
result of the driver expression.
Why/Motivations:
This way, it becomes easier to create corrective drivers, as you can position all
the targets the driver depends on, then adjust the driver value until it does what
you need, and then you keyframe that value to bake it into the Driver F-Curve
(in effect, "training" the computer how to behave in that case).
Usage Notes:
* In practice, that particular workflow is still quite clunky to achieve, due to some
quirks of how the driver system and the UI widgets interact. Specifically, you'll
need to disable/mute the driver before trying to edit the setting (to prevent the
driver from immediately resetting the value - before even autokey fires!). However,
if you're using the Graph Editor to preview/monitor/manage the keying process, you'll
then want to re-enable the driver before changing the targets, so that you can see
how much of a change you'll want to be applying!
* The warning about editing driver values may need to be disabled or selectively
knocked out. I had it disabled while testing this functionality, but it's actually
harmless in its current state (if just a bit annoying).

When attempting to change a driver variable name to an "invalid" name,
an indicator will now be shown beside the offending variable name.
Clicking on this icon will show a popup which provides more information
about why the variable name cannot be used.
Reasons that it knows about are:
1) Starts with number
2) Has a dot
3) Has a space
4) Starts with or contains a special character
5) Starts with an underscore (Python does allow this, but it's bad practice,
and makes checking security of drivers harder)
6) Is a reserved Python keyword

autogenerated expressions
While most scripted expressions are quite short (e.g. "var" or "frame + 1"),
those that are autogenerated by scripts (to take into account a wide range of factors)
may require a bit more headroom to operate in.
By doubling the maximum length here, we now make it possible to combine up to 38
3-letter variables in some linear combination (with all factors expressed to 4 dp).
That should be more than enough for anyone or anything for quite a while!
Unfortunately, this does increase memory consumption for drivers across the board.

Windows"
White the config itself could be loaded this way, lookup tables can not. Additionally,
that's not really clear how to solve the issue with search path which is multi-byte
only in the API.
Reverting for further investigation.
