Workbench: Shadow: Add support for completly manifold geom.

If a mesh is known to be manifold, then it's not necessary to increment the
stencil buffer 2 times anymore. But we still need to account properly for
degenerate triangles.

In this case, only generate a quad if the tri is facing the lamp. If there
is a degenerate loop, the other edge will either cancel the increment (if
it is also facing the light) or not produce a quad (if not facing).

This will always give the correct count.

DRW: Rename some DRW_STATE_* for more consistency.

Workbench: Shadow: Add Depth Fail method

Also add new debug visualisation.

Depth fail method is not used for the moment but has nice benefits. It will
be used efficiently in the future.

Workbench: Precompute light direction in object space.

Avoid 2 matrix multiplication in the shader.

Workbench: Shadow: Add geometry instancing extension.

This give a very slight perf boost. (2ms gain over 67ms total in my test)

Workbench: Shadows: Fix corner case with degenerate triangles.

Seems that degenerate tris are somewhat widely used in modeling. So we need
to fix this. Test the edges in the geom shader since the adjacency info is
only dependant on topology, not actual vertex placement.

This fixes most of the remaining noise issues. Only a few artifacts appear
on really weird models. So if you want to get rid of the artifacts, fix
your model!

Workbench: Optimize Shadows.

This makes the shadows ~10 times faster in the general case.

This only create extrusion geometry on the outline edges. Also we increment
or decrement the stencil buffer by 2 for each manifold edge and only by 1
for non manifold. This make the algorithm robust yet less heavy than creating
one prism for each triangles.

GWN: Add Line Adjacency primitive support.

Fix: crash when rotating the view in pose mode

UI: locate popover w/ active item under cursor

Use when popover has no parent, useful for accessing the toolbar.

Cleanup: line length

Cleanup: whitespace, duplicate includes

Hacky Fix: Changing frames by setting Scene.frame_current directly didn't update rigs in 3D viewport

Operators did not suffer from this problem as they were still just using notifiers
directly. The "proper" fix is to use the new message bus system. But, we've
got enough problems dealing with COW already as it is now... moving on.

Fix: When trying to transform animated bones, they would jump to and use random old values

The transform code needed to use data from the "_eval" copy of the posebone
instead of the main-db version, otherwise the initial/reset value would be
wrong, causing the jumping.

Add back temporary exception for pose bones in DEG_get_evaluated_rna_pointer()

Without the exception, adding new poses to pose libraries took several seconds
with only <= 4 bones selected. While we may still need this for other cases too,
since bones are such a common use case, it makes sense to provide some level
of optimisation for them.

Cleanup: Remove temporary debugging code

WIP: Improved implementation of DEG_get_evaluated_rna_pointer()

This now works by getting the RNA Path from the given PointerRNA to go from the
ID block to the data it points to, then uses this path to find the new data
relative to the COW ID.

Note: This currently still has all the debug prints left in - As can be seen,
I was testing this against the earlier PoseBone hack/special case. We may still
need to bring such special cases back in future, since looking up RNA Paths
like this can be slow.
