Add a new hybrid region tracker for motion tracking to libmv, and
add it as an option (under "Hybrid") in the tracking settings. The
region tracker is a combination of brute force tracking for coarse
alignment, then refinement with the ESM/KLT algorithm already in
libmv that gives excellent subpixel precision (typically 1/50'th
of a pixel)

This also adds a new "brute force" region tracker which does a
brute force search through every pixel position in the destination
for the pattern in the first frame. It leverages SSE if available,
similar to the SAD tracker, to do this quickly. Currently it does
some unnecessary conversions to/from floating point that will get
fixed later.

The hybrid tracker glues the two trackers (brute & ESM) together
to get an overall better tracker. The algorithm is simple:

1. Track from frame 1 to frame 2 with the brute force tracker.
This tries every possible pixel position for the pattern from
frame 1 in frame 2. The position with the smallest
sum-of-absolute-differences is chosen. By definition, this
position is only accurate up to 1 pixel or so.
2. Using the result from 1, initialize a track with ESM. This does
a least-squares fit with subpixel precision.
3. If the ESM shift was more than 2 pixels, report failure.
4. If the ESM track shifted less than 2 pixels, then the track is
good and we're done. The rationale here is that if the
refinement stage shifts more than 1 pixel, then the brute force
result likely found some random position that's not a good fit.

flush selected vertices when switching from vertex weight paint mode to editmode (as is done with faces).

note - a limitation with mode changing means this isnt used yet with toggling.

Fix cycles compile issue after last commit.

svn merge ^/trunk/blender -r42361:42372

shorten very long lines in drawobject.c, (no functional changes)

fix for weight paint mode drawing selected verts even when it wasnt the active object.

Fix #29444: cycles problem building BVH with NaN vertices.

Fix #29483: edge slide gives nan when zoomed in close. Cause was integer
overflow leading to negative value for sqrt().

add library support for rna collection __contains__, eg

("Cube", "//lib.blend") in bpy.data.objects

fix for derived mesh buffer overrun caused by using an incorrect loop length.

editmode extruding would crash instantly when dupli-faces were enabled.

Enables vc 2010 boost libraries for cmake

svn merge ^/trunk/blender -r42333:42361

some formatting edits & #if 0 files which are not used.

de-duplicate dominant axis calculation, exact same checks were in 6 different places.
added function: axis_dominant_v3(...)

Fix #27620: improve mesh deform error message when it fails to bind.

Fix #29477: make proxy gave proxy object the wrong name with OB prefix.

Broke in revision 41125 with BLI_snprintf refactoring, checked other
changes in that commit and they seem to be fine, was just this one.

fix for own error - r42200, broke knife tool edge/triangle intersection.

CameraData Input Cycles Node
----------------------------
reviewed and approved by Brecht

Important note:
the camera Z is reverted compared to Blender render.
Now it goes from zero (camera) to positive (in front of the camera)

Fix #29073: keyframing integer properties now uses linear interpolation
by default, and enums use constant interpolation. Bezier doesn't make
much sense for these.

Hook up mesh select_all properties added in previous commit
