For now simply reshuffle option so they keep proper dependency flow.
Benefits:
- Has an ability to hide tracks lists to work with other sliders around.
Could be really handy to quickly get rid of lenghty lists.
- From a feedback seems to be fitting workflow better.
Things to doublecheck on:
- Feels a bit misordered: first you define whether one want to have
rotation stabilized, then have tracks, then scale options.
While this follows dependency flow (which is really good and which
we should not violate) it has weird feeling on whether things are
really where they have to be.
- Autoscale controls visibility of max-scale, can we just make it
active/inactive instead?
- Autoscale replaces slider with label. Can it be disabled slider
instead to reduce visual jumping (disabled slider prevents user
input)
Hopefully we'll still want to have collapsable box after re-iterating
over this points, so we don't waste bits in DNA.

See this page for motivation and description of concepts:
https://github.com/Ichthyostega/blender/wiki
See this video for UI explanation and demonstration of usage
http://vimeo.com/blenderHack/stabilizerdemo
This proposal attempts to improve usability of Blender's image stabilization
feature for real-world footage esp. with moving and panning camera. It builds
upon the feature tracking to get a measurement of 2D image movement.
- Use a weighted average of movement contributions (instead of a median).
- Allow for rotation compensation and zoom (image scale) compensation.
- Allow to pick a different set of tracks for translation and for
rotation/zoom.
- Treat translation / rotation / zoom contributions systematically in a
similar way.
- Improve handling of partial tracking data with gaps and varying
start / end points.
- Have a user definable anchor frame and interpolate / extrapolate data to
avoid jumping back to "neutral" position when no tracking data is available.
- Support for travelling and panning shots by including an //intended//
position/rotation/zoom ("target position"). The idea is for these parameters
to be //animated// by the user, in order to supply an smooth, intended
camera movement. This way, we can keep the image content roughly in frame
even when moving completely away from the initial view.
A known shortcoming is that the pivot point for rotation compensation is set to
the translation compensated image center. This can produce spurious rotation on
travelling shots, which needs to be compensated manually (by animating the
target rotation parameter). There are several possible ways to address that
problem, yet all of them are considered beyond the scope of this improvement
proposal for now.
Own modifications:
- Restrict line length, it's really handy for split-view editing
- In motion tracking we prefer fully human-readable comments, meaning we
don't use doxygen with it's weird markup and comments are supposed to
start with capital and end with a full stop,
- Add explicit comparison of pointer to NULL.

Reduces noise from --debug-gpu so we can spot serious errors.
Blender 2.7x uses OpenGL 2.1, we don't care if features are deprecated.
I'll re-enable these warnings for blender2.8 after next merge.

Backtrace so we can pinpoint where the GL error came from. Then fflush
on severe errors in case it's severe enough to crash Blender.
|

When running blender --debug-gpu
Display which debug facilities are available. One of these, in order of preference:
- OpenGL 4.3
- KHR_debug
- ARB_debug_output
- AMD_debug_output
All messages are logged now, not just errors. Will probably turn some of these off later.
GL_DEBUG_OUTPUT_SYNCHRONOUS lets us break on errors and backtrace to the exact trouble spot.
Callers of GPU_string_marker no longer pass in a message length, just the message itself (null terminated).
Apple provides no GL debug logging features.

cloth stiffness scaling.
When updating the max values under stiffness scaling, they clip at the normal stiffness values
as expected, however when updating stiffness values, you could set them higher than the max
values, and the max values weren't updated accordingly. As the stiffness scaling computes using
the absolute difference between the max values and the stiffness values, you got higher
stiffnesses in scaled areas even though your max is actually lower than the normal stiffness.
This diff fixes that behaviour, by updating the max values to be equal to the stiffness whenever
you set a higher stiffness than the max value.
Also, I have initialized the max values to the same as the stiffnesses, as they were previously
just set to zero, and caused the same problem described above.

socket layout.
Node tree update calls in the middle of a socket loop are dangerous, they can change sockets
on group nodes and link instances in particular. Updates should only happen after the operator
has finished.
Simply removed the extra convenience check for validity now. Worst case an invalid (red) link
is created which can be removed by the user as well and should simply be ignored by node systems.
The update system in nodes needs a complete rewrite to handle complex cases like this, where an
operator may need to react to changes during its execution.

GPencil conversion would just always run for file version 2.77.3. This wasn't an issue in master, but possibly for other branches that used the 2.77.3 block.
Wasn't aware that you have to add the asterisk for pointers either, this is kinda weird. Anyway, it's running correctly now.

New dependency graph puts materials to the graph in order to deal with animation
assigned to them and things like that. This leads us to a requirement to update
relations when slots changes.
This fixes: T49075 Assignment of a keyframed material using the frame_change_pre handler
doesn't update the keyframe using the new dependency graph
|
|
This is mainly required for the new dependency graph where non-object
datablocks are a part of dependency graph.
This solves issue when making mesh shared by multiple objects a single
user one.

Point cache read code contains checks designed to prevent it reading
stale data when the relevant simulation code should instead compute
the next frame from the previous one. However in some situations like
motion blur subframes the simulation can't possibly do it and just
exits. This causes completely incorrect motion blur at or after the
last cached frame.
To fix, add a parameter that tells the cache code whether it should
apply the checks and exit, or read what it can even if stale (true
means exactly same as old behavior).
Doing this in cache rather than clamping the frame number better in
the caller lets it handle the case of incomplete cache that stops
before the official last frame.

Now we free sequencer cache and close all unneeded FFmpeg handles when rendering.
This is the same logic as image sequence memory freeding.

Reported by @panzergame in D1414.
`glDisable` calls with bad enum argument `GL_TEXTURE_2D_MULTISAMPLE` that came from this line:
`tex->target = (n == 1) ? GL_TEXTURE_1D : (samples ? GL_TEXTURE_2D_MULTISAMPLE : GL_TEXTURE_2D);`

The first character of the ID type was used to tag IDs for updates which
is weak since different IDs can have the same first character (for
example meshes, materials and metaballs), causing unnecessary updates of
unrelated IDs.
Now we use a unique index per ID type to tag for updates, unifying IDs
arrays indexing along the way.

Depth buffer values are used by the viewport pan and zoom code to
adjust response scaling factors between mouse and viewport movement.
Letting smoke write to the buffer confuses it and causes the camera
to get stuck and move very slowly inside smoke domains, because it
thinks it is very close to an object.

If the user enable polygon draw and press ESC before drawing something,
the last stroke must not be moved back.

Wasn't copying back local view bytes to object after changing layer.
Steps to reproduce were:
* Split 3D view in default startup.blend
* Enter local view in one of the 3D views
* Move default cube to different layer *in the other 3D view* (the one that's not in local view)
* Try transforming object from 3D View that's in local view (should lag)
|
|
The polygons must move the stroke to back only when polygon is complete
|
|
For artist point of view is very useful to have an option to draw by
default the new strokes on back of all strokes in the layer.
|

During code review a field was renamed, but one line was missing.
|
|
Do not clear continuous drawing. This code was related to a previous
test and must be removed.

From source code history, it seems this behavior is a relic of a very
old limitation when the same object couldn't be both a Softbody and a
Collision object. In those times if somehow both modifiers were added
to an object, Softbody auto-disabled itself and buttons were hidden.
Now however there is no problem having both modifiers on an object,
so there is no point hiding the buttons. The same exact buttons are
available on the physics tab in any case.

As reported in T48928, From Dupli UV is not supported for grid
distribution, and running the normal code as usual simply produces
nonsense data, because fuv is used to hold orco instead of
interpolation factors for uv, and num is zero.
Since support won't be added in 2.78, just stop outputting nonsense.

All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/

Many thanks to everyone involved in this little project, and huge shout
out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini
and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the
custom builds and compile fixes.

There were two issues here. One is that the fix done originally for this
bug only checks for colliding with the same face as the single preceeding
hit. If the particle hits an edge or vertex of the collider, it in fact
hits two or more faces, so the loop ends up cycling between first two
of them and reaches the max collision limit.
The fix is to disable the collider for the sim step once a permeability
roll succeeds, by adding it to a skip list. Skipping just one face causes
some particles to bounce at odd angles in case of partial permeability.
The second problem was that the collider bounced back a small percentage
of particles, and the cause seemed to be that the code was set to flip
the velocity if the particle was just past the collider but still within
collision distance. Inverting both values causes a half permeable collider
to stop particles, so it seems that this if branch shouldn't bounce at all.
