Compositor: Fix transform randomly inverted

Uninitialized variable.

Avoid using `floor` function

It has an impact in performance when used in deep loops.
If area have negative coordinates it will round
toward zero but buffers should be displaced later on to always
work with positive coordinates.

Compositor: Full frame Bokeh Blur and Blur nodes

adaptive_cloth: AdaptiveMesh: collapse edges: edge size criterion

If the edge were to be collapsed, the newly formed edges shouldn't
exceed the edge size criterion (1.0 - small_value).

Cleanup: Fix comment typo

adaptive_cloth: AdaptiveMesh: collapse edges: run flip edges

It is important that the total update to faces of the mesh (collapse
followed by flip edges) is added to the new_active_faces.

Merge branch 'soc-2021-curves' of git.blender.org:blender into soc-2021-curves

GPencil: New Select Random operator

Select strokes or points randomly (similar to meshes).

adaptive_cloth: AdaptiveMesh: collapse edges: initial steps

There are todos but the code roughly works.

adaptive_cloth: mesh: is vert on seam or boundary

adaptive_cloth: mesh: is edge collapseable: make function const

adaptive_cloth: mesh: const version of get checked node of vert

Sculpt Dyntopo: PBVH draw fixes

* The PBVH draw subsystem is now told whether any viewports
have drawtype >= OB_MATERIAL before anything in any windows
are drawn. There are no alternatives given the design
constraints of sculpting, where simply uploading data to the GPU
quickly becomes a bottleneck.

* Fixed flat vcol shading mode.

Cleanup

- Remove unused wmSurface.is_xr member
- Rename "actionmap" to "action_set" in wmXrActionData
- Use BLI_findstring()
- Add modifications note to tinygltf readme
