Detail: Smoke solver and Blender side of smoke now share the same cell length.
First reported by the Sintel artists long ago, again reported by MiikaH.
Part of my Smoke Development Project Phase III.
Works in the same way as double edge node -- not actually multithreaded
but currently it's fast enough to be used in such way. In the future it
might be changed in some way.
Move actual mask rasterization code to BKE so it's resued by old compositor
system and new compositor. Also in the future it might be used to display
mask preview in mask editor.

It is possible to get the old behaviour (handles excluded) by bringing up the
Operator Properties (F6) while in the Graph Editor (this doesn't work elsewhere
due to the context requirements of this stuff).
* The operator creates bones for each input edge (does not subdivide
them like the skin operator does), adds a fake root bone for skin
roots with multiple children.
* The operator adds vertex weight groups to the original mesh.
* Make copy_object_transform() public, used to match the armature
object to the mesh object.

/* Return the index of the edge vert that is not equal to 'v'. If
* neither edge vertex is equal to 'v', returns -1. */
int BKE_mesh_edge_other_vert(const struct MEdge *e, int v);

TL;DR:
* Frame node gets more usable bounding-box behavior
* Node resizing has helpful mouse cursor indicators and works on all borders
* Node selection/active colors are themeable independently
* Customizable background colors for nodes (useful for frames visual
distinction).
pass index, and a random number unique to the instance of the object.
This can be useful to give some variation to a single material assigned to
multiple instances, either manually controlled through the object index, based
on the object location, or randomized for each instance.

This allows different markers has different size of search area which
makes it possible to scale search area when doing planar tracking.
Made changes to all related areas such as transformation, tracking,
finally ported marker clamping function, added python bindings for
changed search area and added python API for pattern corners.
TODO: It's still possible to make marker's center go outside of pattern
corners when translating pattern area or rotating it around median
point.
Change modifier_sameTopology() to not not treat Nonconstructive
modifiers as having same topology. This function is only used to test
whether Apply as Shape is allowed.
The exact nature of "nonconstructive" modifiers is not documented, but
current list is remesh, fluidsim, decimate, mask, build, and
boolean. All of these modify topology, and should not be making making
shape keys.
This commit adds the ability to normalize patterns by their
average value while tracking, to make them invariant to global
illumination changes.
To see this in action, check out the "Lobby" scene from Hollywood
VFX. If you track the markers that are shadowed by the actress,
previously they would not track. With the scale adaption on, the
tracker would shrink the area to compensate for the changed
illumination, losing the track. With "Normalize" turned on, the
patch is correctly tracked and scale is maintained.
A remaining problem is that only the Ceres cost function is
updated to handle the normalization. The brute translation search
does not take this into account. Perhaps "Prepass" (see below)
should get disabled if normalization is enabled until I fix the
prepass to normalize as well.
There are a few other changes:
- Cleanups in tracking RNA comments.
- Bail out of the sampling loop early if the mask is zero; this
saves expensive samples of the image derivatives.
- Rename the wordy "Translation initialization" to "Prepass" at
Sebastian's suggestion.
- Fix a bug where the mask was ignored when sampling in the cost
functor.
