When node face gets deleted, added or exchanged, the nodes should update
their draw buffers, normals and bounding boxes. This was not being done
before so there were graphical glitches apparent, especially in collapse
mode.
This commit does various changes for matcaps:
One is taking advantage of drawing with pbvh (which would only happen
with dyntopo previously) and drawing with partial redraw during
sculpting.
The second one is support for masks. To make this work in the special
case of multires, which uses flat shading, I use the only available flat
shaded builtins in OpenGL 2.0 which are color and secondary color.
Abusing colors in that way is also essential for flat shading to work if
we are to use pbvh draw in multires, since it is the color that is being
interpolated flatly, not the normal (which can only interpolated
smoothly). The pbvh drawing code for multires used last triangle
element's normal to compute the shading which would only produce smooth
results. This could change if we did the shading in the vertex shader
for flat shaded primitives, but this is more complex and makes it harder
to have one shader to rule the mole.
Also increased the brightness of the default diffuse color for
sculpting. This should be useful since artists like to tweak the
lighting settings and it will give them the full dynamic range of the
lights, but also it helps with correct brightness of sculpted matcaps.

Evaluation of time-warping modifiers ("Stepped" is one of them) didn't actually
end up distorting the time to look up what values other modifiers in the stack
generate. This meant that when a "stepped" fmodifier was on top of a "generator",
the stepped fmodifier looked like it didn't have any effect.
(This fix requires a bit of testing still, so should be left for 2.71)
- autodetect optimal default, which typically avoids HT threads
- can store setting in .blend per scene
- this does not touch general omp max threads, due i found other areas where the calculations are fitting for huge corecount
- Intel notes, some of the older generation processors with HyperThreading would not provide significant performance boost for FPU intensive applications. On those systems you might want to set OMP_NUM_THREADS = total number of cores (not total number of hardware theads).
Previously, amplitude was more of an "absolute" value in the sense that whatever value
you set it to became a sort of "maximum bounce" height. However, it turns out that this
approach isn't so nice when dealing with large gaps between the values of two keyframes,
as the elastic easing equations expect that "amplitude > |change|" (where change is the
difference in values from key1 to key2).
Now, the "amplitude" value we pass to the easing functions are "|change| + amplitude".
This is easier to control, as now, as soon as you start changing that value, there are
immediately visible effects.
Summary:
The title actually says it all, it's just possible to
have independent free handles for mask splines. Also
it's now possible to have aligned handles displayed
as independent handles.
Required changes in quite a few places, but they're
rather straightforward.
From user perspective there's one really visible change
which is removed Handle Type menu from the panel. With
asymmetric handles it's not clear which handle type to
display there. So now the only way to change handle type
is via V-key menu.
Rewrote normal evaluation function to make it deal
with new type of handles we support. Now it works in
the following way:
- Offset the original spline by maximal weight
- Calculate vector between corresponding U positions
on offset and original spline
- Normalize this vector.
Seems to be giving more adequate results and doesn't
tend to self-intersect as much as old behavior used to,
There're still some changes which needed to be done, but
which are planned for further patch:
- Support colors and handle size via themes.
- Make handles color-coded, just the same as done for
regular bezier splines in 3D viewport.
Additional changes to make roto workflow even better:
- Use circles to draw handles
- Support AA for handles
- Change click-create-drag to change curvature of the
spline instead of adjusting point position.

Root of the issues comes to the fact that it's possible to produce
a situation when library object data uses local object. This is
actually forbidden and not supported by .blend IO.
Made it so Make Local wouldn't produce such an unsupported states.

Bevel Factor Mapping allows to control the relation between bevel factors
(number between 0 and 1) and the rendered start and end point of a beveled
spline.
There are three options: "Resolution", "Segments", "Spline". "Resolution"
option maps bevel factors as it was done < 2.71, "Spline" and "Segments"
are new.
* "Resolution“: Map the bevel factor to the number of subdivisions of a
spline (U resolution).
* "Segments“: Map the bevel factor to the length of a segment and to the
number of subdivisions of a segment.
* "Spline": Map the bevel factor to the length of a spline.

BKE_sequencer_offset_animdata() was simply assuming bezt member of fcurve was always valid, while it might be NULL (e.g. when fcurve is using FPoints instead, like when generated from sound file).
Issue was caused by inverting a degenerate matrix when
evaluating drivers.
Solved by using tweaked inverse code (same as used in Cycles).
Should have no affect on cases when matrix is not degenerate.
Issue was caused by the cache limitor which was removing 4k textures from the
memory when accessing other images.
This is pretty much awful situation and solved by making it so only image sequences
and movies ace cache-guarded.
Could be optimized further so images used by viewport are not being freed, but
that's much more tricky to do..
This is a nice candidature for 'a'.
Issue is a regression since threaded objetc update and caused
by the fact that some objects might share the same proxy object.
It's all fine but object_handle_update() will call update for
a proxy object which screws up threaded update.
The thing is, proxy object is marked as depending on a scene
object and such a call makes it so the children objetc is
being updated.
This is really bad and depsgraph is to take all responsibility
on updating the proxy objects.
So for now used a simple solution (which is safe to backport
to 'a') which is skipping proxy update if the scene update is
threaded and based on the DAG traversal.
There are some still areas which calls object update directly
and for that cases proxy object is still being updated from
object_handle_update().
Located on topology panel.
To use just click on button and click on mesh.
Operator will just use the dimensions of the triangles below to set the
constant detail setting.
Also changed pair of scale/detail size with nice separate float
percentage value.
Nothing spectacular here, fill tools are easy. Just take the dyntopo
code and repeat until nothing more to do.
The tool can be located in the dyntopo panel when the dyntopo constant
detail is on.
Also added scale factor for constant detail. This may change when detail
sampling gets in, I am not very happy with having two numbers here,
still it will give some more control for now.
This commit introduces support for a number of new interpolation types
which are useful for motion-graphics work. These define a number of
"easing equations" (basically, equations which define some preset
ways that one keyframe transitions to another) which reduce the amount
of manual work (inserting and tweaking keyframes) to achieve certain
common effects. For example, snappy movements, and fake-physics such
as bouncing/springing effects.
The additional interpolation types introduced in this commit can be found
in many packages and toolkits (notably Qt and all modern web browsers).
For more info and a few live demos, see [1] and [2].
