Fix (unreported) crash in mesh remap (i.e. data transfer).

Issue from rBabbd82a50, loops data were not correctly protected against multi-freeing in bvhtree data.

Mesh remap: Fix two potential numeric issues in corner cases, and enhance poly projection.

Null-area face could generate an int overflow, and potential numerical imprecision in face area computation
could lead to negative number of rays-to-cast (though highly unlikely).

Also, use domnant axis of poly normal as 'flattening' one, instead of always using Z axis.

Points raised by Campbell, thanks!

Attempt to fix T45718, crash when enabling GLSL mode with UV layers.

I can't reproduce issue here but crash is most likely caused by passing
a NULL pointer to glUniform2fv.

This is caused by OpenSubdiv changes to the codegen module, which pass
mtex layers to the uniform system
even when not needed.

Since Sergey is demoing OpenSubdiv in a few days, I'll
go with the easy fix for now which is just checking for NULL pointer, but
this needs to be fixed properly at some point.

Fix scrubbing only treated as animation for sequencer

Intent was to act as animation everywhere

Fix T45713: Numselect for confirm popup not working anymore

BGe: Fix T45597 wrong object layer for linked object in blenderplayer.

Fix: Sliders in animeditors were getting drawn too far left

Sliders in for FCurves in the animation editors were leaving space for
one extra setting that they didn't need to be accounting for (and which
wasn't shown, as it isn't valid for FCurves).

AnimEditors FModifiers toggle: Add a bit more space beside it so that it doesn't seem to collide with the mute toggle

Fix T45166: Keyframes pasted at wrong position when NLA strip has offset

Paste keyframes code seemed to have overlooked the NLA mapping issue, causing
keyframes to get pasted in the wrong places.

No need to count layers to check empty

GPencil UI: Streamline the data panel workflow

Restored the "New Layer" button in the NKEY Grease Pencil panel (as was found
pre-2.73) for two cases:
1) When no Grease Pencil datablock is active - This shortcut makes it possible to
add a new layer to start drawing in with a single click again (instead of two
clicks - one to add a datablock, and a second to add the layer)

2) When there are no layers - There is no need to display the UI list in this case,
thus saving a bit more space in the rare cases where this applies.

T44932: Disable pressure handling for "poly" mode too

StopGap Fix for T44932: Ignore pressure values when drawing straight line segments with GPencil

After some testing of the behaviour of this stuff, it became clear that the current
pressure handling here isn't very useful. The initial point would invariably get a
low pressure value (due to the way that the initial tap needs time to "take"), while
the end of the stroke suffers from similar issues (i.e. when the pen is released).
Meanwhile, the line thickness would flicker while drawing the stroke, as the endpoint
pressure varied.

So, until we find a better way, all straight line segments are now drawn without
pressure sensitivity.

Timeline: Make GPencil keyframes slightly taller than normal keyframes to make them easier to distinguish

This commit makes GPencil keyframes in the timeline slightly taller (80% height
vs 60% height) so that they will not be that easily confused.

Remove MFace use w/ fluidsim

Docs: comment BKE_scene_set_background

Fix typo in cmake when OpenSubdiv is not found

Fix T45695: Assigning material reverts MaterialSlot.link

Setting the material was resetting the link bit, this is OK from the UI,
confusing for scripts.

OpenSubdiv: Make sure faces are exported with consistent normal

This is currently a requirement of OpenSudiv and original orientation code
was depending on this quite a lot.

This makes mesh conversion and comparison slower but solves some crashes.
With some trickery it could be optimized and become closer to original
performance.

Probably Campbell has some nice ideas here as well :)

Simplify defvert_remove_group(), use realloc
