This is not limited to normal maps, it's just that normal maps cause a
mix of interleaved vertex arrays + non interleaved vertex arrays + GLSL,
which could confuse the GL. Possible explanation is that it may be
clobbering the vertex index of the shader somehow but this is difficult
to know without extensive tests and the Mac is needed by Francesco in
the morning :).
Do brute force solution instead, just force legacy drawing on Macs when
VBOs is off. On the plus side VBOs work fine, so we should be fine when
we update.
The smoke obstacle detection was using a maximum distance for BVH
checks to find mesh elements that define boundary cells in the grid.
This BVH test was using an arbitrary value of 0.6 cell units. It should
be `sqrt(3)*0.5` to account for the maximum possible distance of mesh
elements inside a cell. Otherwise some cells that should form the
boundary are not detected as such (no closest mesh element found inside
the radius), so you get gaps in the smoke obstacle.
Now we have an helper that will generate local/global paths and ensure they are valid.
Note: We currently have no way to 'generate' a valid extension in these cases, so just
using raw (file-safe) ID name.
* Do not make Action Stash Tracks or their strips active/selected
* Lock the track to prevent accidental editing/adding of other strips
* Prevent strips from being added into locked tracks by the pushdown operator.
This is mainly to prevent pushdown actions from getting into the stash tracks.
The Solo and Mute functionality for the NLA system should really be mutually
exclusive features. They both affect whether a given track applies or not.
The only difference is that the Solo option mutes all the others, while the Mute
only does this on a per track basis.
Before this fix, muting a strip and then making it solo meant that the solo'd
track would not play at all, which isn't really what we want.
frame start.
Issue here is that if we failed to get an image from the cache, we would
try to load from file. This would fail when the queried frame was less
than the animated sequence start frame, and invalidate the OK state of
the image.
Solution is that when loading from cache succeeds, we also reset the OK
state of the image for animated textures.
The fix might be relevant elsewhere too, but kept it isolated just in
case.
`CustomData_bmesh_interp_n` was expecting the 'dest' arg not to have its offset applied.
This was a bit confusing since the source args have it applied,
and in some cases we only have the destination with the offset.
Fix for T43768
This way it works consistent with cloth, softbodys, etc.

New Lock Z velocity parameter was added. This parameter avoid the micro-jumping.
By default it is actived except when you load an old file that it is deactived to keep former behaviour.
Additionally it was solved another issue related with the acceleration: That is the acceleration value was not taked into account and we had always the maximum linear velocity from the beginning of movement. Now the acceleration is taken into account until we reach the maximum velocity.
When you load an old file, the acceleration value is set to the maximum range (1000.f). This way we simulate a maximum velocity constant from the beginning of movement (former behaviour).

Our new guarded allocator implementation has much smaller memory
block size overhead and doesn't have any locks now. So in order
to make fuller track of what's happening in blender and avoid
confusion why certain circumstances reports much less memory than
others we'll now switch to guarded allocator.
This was actually one of the biggest reasons of the confusion in
the recent memory usage investigation. There's still some overhead
is happening due to non-freeing nature of arena allocator but the
things are not nearly as bad as they looked before: memory overhead
is measured in tens of megabytes, not hundreds as it looked before.
Plus with some smarter allocation policy we can almost eliminate this
overhead.
