Replace "cent" functions from math_geom with "mid" ones from math_vector

Use overall matcap colors as AO color avoiding completelly dark areas.

Constify some stuff (for clarity and correctness)

Merge remote-tracking branch 'origin/blender2.8' into render-layers

Add new objects and some Base > ObjectBase convertion

New objects are properly added to the correct collection, and are synced
into the correct collections.

Added SSAO to give cavity / Edge highlight effect.

Fix selected_objects iterator

rename ob_base > base, it will simplify further refactors

Fixed vertex selection being ignored.

Removing Bases from clay.c and other fixes

Listbase was used wrongly in draw_manager, using LinkData elements now

Merge remote-tracking branch 'origin/render-layers' into clay-engine

Fixup for iterator

(this is a placeholder anyways, what we really need is DEG_OBJECT_ITER()

Adding FOREACH_OBJECT iterator

Add properties to clay material (not exposed yet)

Merge branch 'master' into id_override_static

Working proof-of-concept of differential override operations.

So, now 'proportional' RNA properties (here, Object's scale) is stored
as 'multiply' override op.

Once again, this is mostly testing for now, there are a lot of potential
issues and traps in current code that'll need more background work to
address later if we keep working in this direction.

Main remaining TODO to complete the proof of concept now is sketching
out a bit of UI/UX control over override!

retain existing creases, added inner crease and interpolate edge data with carve now

Merge branch 'master' into id_override_static

UI Cleanup: Add new property scaling panel

UI Cleanup: Add dedicated cloth shape panel
