Fix T60507: Constrained transform shows all axes

Regression in 579c01da600dd

Move values_modal_offset use out of applyMouseInput
to resolve order of initialization issue.

Revert fix for T48901: Use of XIWarpPointer

Xorg's XIWarpPointer doesn't support multi-head display while
XWarpPointer does.

Revert since this is a known TODO in Xorg and setting a custom
xinput matrix seems not to be used often.

Resolves T50383

Fix T60504: Armature wire draw type hidden when unselected

Fix T60506: Menu toggle clicks pass through to area

CMake: Improve handling of missing TBB & OpenVDB

Fix T60512: Weight paint brushes show weight when unused

Cleanup: use BrushCapabilities prefix for RNA types

Cleanup: style

Edit Mesh: Improve selected double vertices visibility

The issue is that the edge fix geometry goes on top of the actual drawn
points.

This commit reduce the edge fix size to the strict minimum but does not
get rid of it.

UI: indent subpanel headers more.

Windows: add support for Windows Ink.

Before this Blender always needed the Wintab driver. This adds support for the
native pressure API in Windows 8+, making it possible to get pressure sensitivity
on e.g. Microsoft Surface hardware without any extra drivers.

By default Blender will automatically use Wintab if available, and if not use
Windows Ink instead. There is also a new user preference to explicitly specify
which API to use if automatic detection fails.

Fixes T57869: no pressure sensitivity with Surface pen or laptop.

Code by Christopher Peerman with some tweaks by Brecht Van Lommel.

Cleanup: refactor GHOST wintab handling.

Fix T60476 Loose vertices only partially drawn

Was caused by a missing vbo attachement.

Also fix said Vbo refreshing when selecting.

Object Mode: Outlines: Add support for thicker outline

Base outline is 2px wide (because of how we detect them).
And since inflating this outline will only produce outlines that are 2*x
thick we map the UI scalling and the outline width setting to the closest
match.

Do note that thicker outlines have a performance cost since they need more
texture fetches and passes.

This fixes T60252 3D View Outline Width not working

GPUMaterial: Cleanup

Fix T60332: Lattice objects do not display properly in Edit mode

NLA: implement a new blending mode that intelligently combines actions.

The existing Add and Multiply blending modes have limited usability,
because the appropriate operation for meaningfully combining values
depends on the channel. This adds a new mode that chooses the operation
automatically based on property settings:

- Axis+Angle channels are summed, effectively averaging the
axis, but adding up the angle. Default is forced to 0.

- Quaternion channels use quaternion multiplication:

result = prev * value ^ influence

- Scale-like multiplicative channels use multiplication:

result = prev * (value / default) ^ influence

- Other channels use addition:

result = prev + (value - default) * influence

Inclusion of default in the computation ensures that combining
keyframed default values of properties keeps the default state,
even if the default isn't 0 or 1.

Strips with this mode can be keyframed normally in Tweak mode,
except that for quaternion rotation keyframing always inserts
all 4 channels, and the channel value sliders on the left side
of Graph/Action editors won't insert keys without Auto Key.
Quaternion keys are also automatically normalized.
