When the desired widths (offsets) of beveled edges cannot be
satisfied, often because we want them to meet on an intermediate
non-beveled edge, we need to compromise on the widths somehow.
This code changes the compromise to minimize the sum of squares
of errors in the offsets. It also adds a global width consistency
pass: starting from a vertex that needed width adjustment, it
uses a breadth-first search to try to propagate the adjustments
and keep the bevel widths from having to taper along the edges.
Also fixed a case where a reflex angle would cause bad results.
Also fixed the way the 'percentage' width method was calculated.
Issue was caused by linear float buffer creating for every working
thread. This buffer actually duplicated original buffer which doubles
amount of required memory.
We can not avoid such a duplication, because OCIO needs to work on a
float buffer and it modifies this buffer.
Alternative for now is to not allocate linear buffer for the whole chunk
which needs to be handled by the thread and use further chunk cutting in
thread itself.
So now every thread will handle the chunk in blocks of 64 scanlines.
This reduces memory overhead significantly without speed loss in own
tests.
Ideally, IMB_processor_apply_threaded need to be switched to generic
task scheduler and made it so this function generates tasks with
reasonable number of scanlines. This requires much more testing to
be sure there're no conflicts with object update and so.
Such a change to IMB_processor_apply_threaded would not be noticed by
users, so do not consider this is a crucial to do right now.
- could crash if triangulate attempted to create an existing face.
- tagging edges to rotate was unreliable, don't do this anymore.
now check if edge is in the array passed to the beauty function.
Simple/predictable polygon filling functions (no hole support)
originally from libgdx which have some advantages over scanfill.
- always creates the same number of triangles (never any missing faces).
- gives same results for any affine transformation.
- doesn't give so many skinny faces by default.
made some changes for Blender.
- remove last ears first (less to memmove)
- step over the ears while clipping to avoid some verts becoming fans to most of the other.
The property sensor was using CValue::FindIdentifier(), which does an AddRef(). However,
the property sensor was not calling Release() when it was done with the value. This could
cause more leaks when used in conjunction with the copy property actuator since it would
really throw off ref counts.
This attribute allows to open a blend file as an alternative
start-up file. The attribute is only available from python.
This is an example call:
bpy.ops.wm.read_homefile(filepath='path/to/a/file.blend')
This patch also changes readfile.c to ensure that unintentionally
stored cursor states are not imported from the loaded file.
Changes for VC2013
Now, I can build Blender with VC2013 with Cycles, Collada, OpenExr,OpenImageIO disabled. Also, you need VC2008 sp1 installed to make old libs compatible.
Summary:
Now it's possible to assign an image to plane tracks
in clip editor. This image is only used for display
in clip editor and this image is being warped into
the plane track rectangle.
Main purpose of this is to get early feedback about
how good image warping matches the footage, before
clip goes to the compositor.
Pretty much straightforward change: just compute
homography from undeformed normalized frame corner
coordinates (unity square) to plane marker corners
and apply this matrix to opengl stack.
Still could improve behavior when perspective
plane transform is degenerate, but that's not so
much critical for now i'd say.

Summary:
Makes readfile.c more clear and easier to navigate in.
We would need to do such a move when we'll do 2.70 bump
anyway. So better be prepared.
In fact, as soon 2.70 bumo is done i would think we'd
better create versioning_270 file and do version code
there. Otherwise readfile.c will grow up dramatically
again.

There is a bunch of internal refactoring going on too:
* No longer use operators to handle these directory and file fields, only makes
things more complicated than they should be.
* Handle autocomplete partial/full match deeper in the UI code
* Directory field still does not keep focus, that's for another time to fix,
you can already do pretty quick keyboard only navigation with the file field.

- when 3 verts are selected ensure the normal is flipped on the side of existing vert normals.
also use the most distant 2 verts to define the tangent.
- when 2 vertices are selected, the normal wasn't aligned with the vert normal.
