Add Ctrl keymap while fill for free drawing

If press Ctrl key while using a fill brush, the brush is used as a normal drawing brush and the artist can draw any shape freely.

Subsurf: Allow partial threading over geometry arrays

This helps avoiding threading overhead when having lots of system threads..

Mesh evaluate: Tweak threadability criteria

Gives measurable speedup on layout scenes from Spring.

Actual value for chunk size is a subject for more scientific research.

Mesh deform: Tweak threadability criteria

Allow threading using subset of all available threads. Makes it faster to
evaluate lower resolution mesh but with complex deform groups and such.

Subsurf: Make copyFinalLoopArray() threaded

Gives about 40% speedup of object which has simple-ish deformation applied
on top of subdivided mesh.

This might easily happen with single character animation.

Depsgraph: Make eval initialization more friendly for threading

Helps in cases of not very complex scenes and lots of system threads available.

A bit hard to measure change on it's own, it works best with the upcoming
changes and gives measurable improvements.

Subsurf: Use regular mutex instead of RW one

Mutex is now local to particular CCGDM, and guarding edge hash which is only
used by a single function only. There is no need to acquire read lock after
edge hash was created.

Merge branch 'master' into blender2.8

Conflicts:

source/blender/makesdna/DNA_ID.h

Fix critical issue with our DNA ID tags (two totally different tags having same value).

Nice typo from rBc4046e9082f6, tssk. ;)

Fix static override (very stupid mistakes in code!)

Fix error after merge

The function name has changed

For fill brush use only fill colors

If the brush is for fill, the list of color must be limited to fill colors only, except the flag to override this, is enabled.

Small adjust to panel size

Change panel back color

Add a pattern to see alpha colors

If the color has alpha, need a pattern to see the transparency effect.

Add diagonal line if fill color

Add a line if the color box include stroke and fill color.
