Merge branch 'master' into blender2.8

BMesh: move safe loop-normal-calc to own function

This makes sense when we want to avoid float precision error
for near co-linear edges. OTOH, this is an arbitrary decision,
so keep functions separate.

Fix error if use several GP objects

The flag was set wrong

Fix color distorsion while drawing

Need to use the mix_pass in order to get the same color while drawing. If the pass is not mixed with the same pass than strokes, there is a change in the color between drawing stroke and final stroke due the process to mix.

This is slower, but needed and while drawing the time delay is negligible

Merge branch 'blender2.8' into greasepencil-object

Create new panels for stroke and fill parameters

Merge branch 'master' into blender2.8

Rename volumetric stroke type

Cleanup: unused vars

Merge branch 'master' into blender2.8
