BMesh: replace smallhash flag for checking doubles

BMesh: avoid over-counting vert-edges

Cleanup: headers

SCons: Ignore .svn folder when installing site-packages

Revert commit with perspective depth offset, makes simple cases such as
loopcuts on cube have zfighting.

SCons: Fix wrong flags usage after recent stdc89 changes

CCFLAGS are used for both C and C++ compilers and one is better not to pass
C-related flags to C++ compiler. C-compiler flags are to be passed via CFLAGS
variable.

Buildbot: Fix typo in error message

RenderResult should have a valid view whenever possible

Rewind fix for T44505 (leave in ifdef'd)

This makes selection fail in simple cases,
default cube subdiv 10x for eg.

Error in last commit

Store bit-depth for reuse, replace loop with shift

Compilation error fixes for strict compiler flags

Fix ortho part of T44505

In this case we can calculate an offset without worrying about
perspective correction. Unfortunately if looking from a camera we still
have depth issues here. There's no really general case that can fix this
so I'm leaving this as is.

Fix T44404: freestyle crashes blender.

The reported crash case seems to be caused by freeing compiled Python
objects in a thread. Now this issue is avoided by allocating a buffer to
store a Python script and using BPY_string_exec() to run the script. This
makes it unnecessary to repeatedly create and destroy Text data blocks.

Many thanks to Campbell Barton for his help on the bug fix.

Alleviate somewhat the issue of T44505

Issue is zfighting with wire of mesh when parts of the mesh are close
together. We can make this slightly better by reducing the offset,
however this offset is calculated pre-perspective division and can vary
greatly with distance. Correct approach would be using polygon offset,
however we draw mesh wireframes as lines, (not polygons with polygon
mode line) so this approach will not work.
Alternatively, we could set an offset in a shader, however we don't have
code for that either.

Curves: don't use 'charidx' for regular curves

Code attempted to sync them with materials,
but its not needed (and wasn't reliable).

Fix T44522: loop remapping between meshes when using 'nearest vert, best matching normal' modes
would fail on coplanar faces (or smooth verts).

Loop remapping is really a tricky topic... For now, we enhance a bit more
our Frankenfunc by using distance between dest and source polygons as
fallback in case we have too much similar normals...

Probably not a perfect solution, but should be robust enough I hope.

One core question remains open though: do we want to stick to 'use only seams
to detect UV islands'? This makes things much simpler, but will obviously fail
in case of actual islands without matching seams. :/

Minor cleanup in comments.

Fix T44516 grid lines obscuring selection outline.

Was changed to draw after meshes without depth mask to make grid not
contribute to compositing effects. Now only draw it like this when we do
compositing (unfortunately can't have both).
