changes to grid fill
- use 4 weights for vertex customdata blending (was previously only using 2)
- option for simple blending, which blends locations using weights too and doesn't attempt to maintain the shape,
useful for flat surfaces or times when keeping the shape gives odd results.

missing NULL check in recent commit, also skip some calculations in mean_value_half_tan functions for degenerate cases.

avoid divide by zeto in node preview drawing.

rna wrap WM_cursor_warp

wrap cursor setting so python can make use of it, eg:
- win.cursor_set('WAIT')
- win.cursor_modal_set('TEXT')
- win.cursor_modal_restore()

rename cursor setting functions to make modal set/restore more clearly related functions.

Code cleanup / Cycles:
* Some cleanup for disabled Volume code.

3D View: add shift+Z shortcut key to switch to Rendered draw mode.

CMake and scons update to detect OS X 10.9, cmake patch by Jake Kauth.

Fix #36672: outliner allowed to toggle linked group visibility, which should not
be allowed because this is linked data, so any changes would not be saved.

Woops, minr style changes are needed.

Avoid tracks reallocation and planes traversal in tracks_map_merge

Would save us a bit of time when doing 2D tracking.

On the second thought, no need to go between straight and premul when doing AA for plane warp node

grid-fill support for customdata, so filled areas have UV's, vertex colors etc interpolated from the boundary.
also support cases where only some of the boundary edges have faces to interpolate from.

bmesh utility functions BM_face_as_array_loop_tri, BM_face_as_array_loop_quad
also set attributes for the header and remove debug print in mask.c

fix for barycentric_weights_v2_quad() divide by zero when the location we're checking the weight of touches one of the weighting coords exactly.

error in recent gridfill commit, calculating span last failed.

starting blenderplater wasnt flipping use_deprecation_warnings when it should, also use values directly without converting to ints.

fix for bug in GHOST/SDL, events dont always have a window (which ghost needs).
fallback to the window with the active opengl context.

BGE Fix: [#32360] Standalone Player switches not working

Launching the player from the Blender UI now makes use of the "Debug Properties", "Framerate and Profile", and "Deprecation Warnings" options by setting the appropriate command line flags.
