fix potential memory leak

another implementation attempt for external constraints

first attempt of brickify fracture

Fix part of T53080: don't use current scene world for icon previews.

This can be very slow if it contains a big texture, and it's not
necessarily setup in a useful way anyway, and materials can be used
in multiple scenes.

fix for "double rotation" in bind

if both objects were rotated, rotations were added up unnecessarily.

fractal boolean with regular alignment, animation bind tweaks

inner material is part of presets now

Fix (unreported) crash when duplicating a FileBrowser window in preview draw mode.

We did not clear preview or smoothscroll timers pointers in copy code...

Fix missing group duplicated by hair in render

Was happening when viewport visibility on the particle system is disabled.
This became an issue after c45afcf, but the actual issue goes a bit deeper
and the following aspects were involved:

- Relations builder for particle system was ignoring particle system if
it's visibility is not enabled for viewport. This is something what
shouldn't have been done -- depsgraph relations are supposed to be the
same no matter if it's viewport or render.

- Relation builder was only dealing with duplication set to object, but
was ignoring group duplication.

This is NOT a regression since 2.79, but a regression since 2.79a-rc1.

fix an ffmpeg qtrle crasher

Fix T53686: VSE Render crash when zooming timeline.

Epic fail from recent 'security' fixes (rBe04d7c49dca9). ;)

To be backported to 2.79a!

Fix T53962: Cycles OpenCL compile error in some scenes.

This part of 212a8d9e needed to be ported over for 2ca933f to work.

Fix possible concurency issue in mesh normals computation.

Failure in own code from last December, thanks @sergey for finding it.

To be backported to 2.79a.

Fix T52634: EditMesh Remove doubles could hang

A single diagonal axis was used for sorting coordinates,
the algorithm relied on users not having vertices axis aligned.

Use BLI_kdtree to remove doubles instead.

Overall speed varies, it's more predictable than the previous method.
Some typical tests gave speedup of ~1.4x - 1.7x.

BLI_kdtree: utility function to remove doubles

animation bind rotation fix, some dynamic mode fixes

IMB: Add asserts that returned fps and fps base are strictly positives.

Forgot to add that in previous commit, also related to T53003.

Related to T53003: tweak scene fps range.

Move restricted 'reasonable' range to ui_range, and allow wider values
for manual settings.

Fix T53003: IMB: Invalid framerate handling due to short integer overflow.

FFMPEG uses int for the numerator, while Blender uses a short. So in
cases people gave weird exotic framerate values and we cannot reduce
enough the numerator, we'd get totally weird values (even negative frame
rates sometimes!)

Now we add checks for short overflow and approximate as best as possible
in that case (error should not matter unless you have shots of at least
several hundreds of hours ;) ).

Fix part of T53080: all material previews re-rendering after undo.

This reverts commit dc2617130b2e1d7d2b9892fbd7c6e7b60caafb66, which disabled
writing of previews for undo. While this uses some memory, re-rendering all
previews is very expensive, especially if for example you have lots of materials
using high-res image textures.
