With multiple branches it was possible the search could run for a long time,
especially when there was no possible path to the target.
Now use a heap to keep track of the best path and finish immediately once its reached.
Two issues here, normal update was not happening due to own sillyness in
viewport refactor, also normal update code still used triangles.
Now reused Campbell's poly normal recalculation code.
This is an alternate fix for T40964 which resolves bad handling of
caustics reported in T45609.
There were too much transmission rays being discarded by the original
fix, which caused by caustic light being totally disabled. There is
still some room for investigation why exactly original paper didn't
work that well, could be caused by the way how the pdf is calculated.
In any case current results seems rather correct now.
Note that the collision modifier doesn't have any use for Loop indices,
so to avoid duplicating the loop array too,
MVertTri has been added which simply stores vertex indices (runtime only).
Notes:
* Code in rendering and in game engine will still convert
tangents to a tessface representation. Added code that
takes care of tangent layer only, might be removed
when BGE and rendering goes full mlooptri mode.
* Baking should work discovered some dead code while
I was working on the patch, also tangents are broken
when baking from multires (also in master), but those
are separate issues that can be fixed later.
This should fix T45491 as well
plane.
Make sure sculpt plane is recalculated for every tiled dab.
Note this is not the optimum thing to do, we could cache the original
sculpt plane and reuse that, but this would require us to rearrange the
logic of tiled sculpting somewhat. This can be a TODO, but for now this
will fix the issue.
* Did not check data2, this partially fixes T45583.
* Initialize data2 in some closures to avoid potential problems.

Basically it's a clean keyframes tool, but also removes a channel if the
only remaining keyframe has the default value only and is not used by
drivers or generative modifiers.
It's was used to help with performance of keyframe-heavy scenes in
gooseberry.
Note, as always the curve left after the clean tool is used is not the
same as the original, so this tool is better used before doing custom
editing of fcurves and after initial keyframe insertion, to get rid
of any unwanted keyframes inserted while doing mass keyframe insertion
(by selecting all bones and pressing I for instance)
Originally D966 by @lukastoenne, with own additions
- trees can be initialized from Object's, BMesh,
or passed in as vert+polygon arrays.
- original indices of ngons/faces are used. (instead of tessellated indices).
- ray_cast, find_nearest methods
- find overlapping faces between 2 trees
