Workbench: Matcaps: Fix matcap under perspective.

This fixes the problem that matcaps have when using a very larg FOV in
perspective view.

This was because it was stupidly using the normal direction which can not
aligned with the view vector under perspective.

So to workaround this problem we don't use the normal as is, but compute
how much it's facing the camera.

This changes how matcaps looks in perspective because they now always use
the full range of the matcap (which is expected).

GHOST/X11: Correct non-latin kb workaround case

Harmless since this is always enabled,
only do this for easier troubleshooting when disabling the define.

GHOST/X11: support accessing physical keycodes

This means we can check keys such as tilde in a generic way.

GHOST/X11: Map unknown us.intl key to accentgrave

WM: correct recent change to click/drag detection

fb1915d87090a - caused click/drag events not to be detected.

Now check a key is a mouse or keyboard event.

Depsgraph: Remove no longer needed nodetree values copying on eval

Note: Depsgraph still calls the nodetree eval function that doesn't
nothing in turn. We can remove it, but it is harmless though.

UI: clear properties color when empty

Sculpt/Paint: move PBVH building to use evaluated mesh instead of deprecated Derivedmesh.

Pretty straightforward changes, merely mimicking dm-related code,
which was already essentially using either Mesh or BMesh data to
build the PBVH...

Note that we "lose" the subsurf (a.k.a. grid) PBVH case here, but that
one was already dead code in current blender2.8, since final dm is
always a cddm built from evaluated mesh.

Proper fix is pending new code for subsurf/multires area.

UI: remove tools space type, use properties context

We've decieded to use tools context in properties editor.

DRW: Fix animated material not refreshing

This introduces a garbage collection system similar to gpu_texture.
