Fix part of T50634: Hair Primitive as Triangles + Hair shader with a texture = crash

Wrong formula was used to calculate needed verts and tris to be reserved.

Cycles: Experiment with replacing Sharp Glossy with GGX when Filter Glossy is used

The idea is to make it simpler to remove noise from scenes when some prop uses
Sharp glossy closure and causes noise in certain cases. Previously Sharp Glossy
was not affected by Filter Glossy at all, which was quite confusing.

Here is a file which demonstrates the issue: {F417797}

After applying the patch all the noise from the scene is gone.

This change also solves fireflies reported in T50700.

Bring back border selection

Prevent crash when copying object

ob->collection_settings is to be handled by depsgraph, but we may as well make sure things do not crash meanwhile

Fix missing break setting curve auto-handles

Outliner: Don't use alphabetical sorting for collections

Order of collections matters, so sorting the outliner entries to be
alphabetical is misleading.

Clay Engine: fix shader :/

Clay Engine: Edit mesh overlays

Based on the previous overlay shader from merwin.
This shader takes care of clipped vertex cases and do all edit mode face info in one pass (except face centers).
As the shading is done one the triangle itself the visual can't go beyond the surface of the mesh. That leads to half displayed edges on the outline of the mesh.
This problem can be fixed by a second pass.

This is work in progress.

Clay Engine: Replace if() by assert()

Fix outliner "Sort Alphabetically" having not working

Fix unreported bug: Ensure you have the correct array directory even after the `dm->release(dm)`

Improve add-on UI error message
