Update Flatty Light theme with topbar and minor tweaks

DRW: Fix incorrect blending function reset.

Modifier stack: move vgroup editing modifiers to new Mesh-based system.

Some notes here:
* Proximity with non-mesh objects (like curve, see TEST_2 scene in
weightvg testfile) are not working currently. This is known TODO of COW
depsgraph project.
* Proximity modifier is slower, due to some other TODO pending on
BVHTree creation/caching for Mesh.

Modifier stack: add new get_texture_coords_mesh() helper.

Will eventually fully replace get_texture_coords().

Fix ARMATURE_OT_layers_show_all now works with COW

Merge branch 'master' into blender2.8

Fix (unreported) memleak when copying object with some modifiers.

Merge branch 'master' into blender2.8

Cleanup: rename char/float conversion functions

- FTOCHAR -> unit_float_to_uchar_clamp
- F3TOCHAR3 -> unit_float_to_uchar_clamp_v3 (swap args)
- F4TOCHAR4 -> unit_float_to_uchar_clamp_v4 (swap args)
- FTOUSHORT -> unit_float_to_ushort_clamp
- USHORTTOUCHAR -> unit_ushort_to_uchar

Cleanup: move unit char/short/float to functions

This caused GCC 8.1 to crash at build time,
but was also not very nice use of macros.

Armature: Transparent Bone: Fix envelope not being alpha blended.

Armature: Add new Transparent Bone overlay option.

This is half the replacement of the old wireframe mode. It's not doing any
XRay drawing at the moment.

DRW: Do not multiply alpha or color by alpha if not in blend more.

DRW: Add DRW_pass_state_add and DRW_pass_state_remove

Fix: Left in debug prints

Fixes for motion path evaluation (part of T54810 work)

This commit brings back motion path calculations working on same level
as 2.7x. Caveats:
* You cannot actually see anything, as all the drawing code for motion
paths was removed and not reimplmented in 2.8 draw engines yet
* This doesn't actually use a separate depsgraph instance for fast
background calculations yet. That's a separate topic, and will require
further investigation (probably after code quest, according to original
planning).
* The work here *does* however pave the path forwards towards fully separate
COW evaluation though. We only need to stub in a different depsgraph instance
here to get things working.

Fix: Tag armature for copy on write when selecting bones, so active bone gets updated

see 8a2d2f1bb40 for similar

Fix T54525: crash when setting number of frames to use between dupoff
frames

caused division by zero if both dupli_frames_on and dupli_frames_off are
zero. doing this doesnt seem useful, dupliframes can be disabled in
other ways.
