OSX: comment cleanup

Fix for a bug in StrokeCleaner identified through a discussion for Bug #36425 (freestyle edge marks not working).
Many thanks for Anthony Edlin who helped fix the issue.

OSX: Final cleanup for #60729

OSX: Get mounted volumes better method by using volume enums

Fix for commit r60718. There was a remaining WITH_IMAGE_OPENIMAGEIO in CMakeLists.txt still.

* Fix scons compilation on Windows, missing pthreads include.

fix [#37058] 2.69 RC1: Symmetrize directions are all reverse

fix for over-alloc in dyntopo, was allocating the vertex size, not pointer size (~85% wasted space).

fix [#37046] Dissolve edges and vertices problem with triangulate
with review and collaboration from Campbell Barton

improve warp transform so it can be used as a general bending tool too.

code cleanup: utility function for getting a bool as a string.

fix [#37034] Triangulate modifier asserts with GHASH_FLAG_ALLOW_DUPES

cmake/openimageio - partially reverting #60692

We now have openimageio building when cycles builds or when it's
manually set to build.

(I reverted the _IMAGE_ in the define name because I think the closer
the cmake flags match the defines in the software the better, and there
is no reason to rename all the existent WITH_OPENIMAGEIO references in
CMakeLists.txt - which would be the alternative)

code cleanup: use more obvious assignments for transform snapping angles.

fix [#37059] OSX Debug - assert when using external screen with MacBookPro

This was old code, Blender now supports multiple screens.
The assert was breaking my builds with -DWITH_ASSERT_ABORT=ON

fix for possible eyedropper NULL pointer use.

OSX/scons: clean message

OSX/scons: rename a confusing (outdated) message

Fix for prefetch not working correct if last frame was loaded

Option to overlay mask over the footage

Currently supports only two modes:
- Show alpha channel of the mask
- Multiply footage by the mask, which will give
you final-looking combined image.

TODO: Currently rasterization happens on every
redraw, need to cache rasterized mask
somewhere to make redraw more realtime.
