MSVC 2013 Compile Fix/Workaround for "static thread_local" vars

Apparently MSVC 2013 has trouble with stuff that's been declared
"static thread_local" (and/or maybe even the "thread_local" keyword).

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'blender2.8' into greasepencil-object

Calculate UVs while drawing

Now the UV while drawing is calculated using same logic used in final UV.

There will be differences between drawing and final due simplify and smooth postprocessing, but the look is more similar now.

Redo UV calculation using color factor

Now the Pixel size ratio is determined by a parameter of the color and not by view pixelsize.

This solves various problems and allow the user define dfifferent effects.

NOTE: Still pending to use the same logic while draw.

Cleanup: Rename function

Use UV randomness UV rotation parameter

New UI parameter to define UV rotation randomness

Fix pattern for Fill stroke

Fix pattern mode for strokes

Now use the alpha channel

Adapt grease pencil render code after last merge

Merge branch 'blender2.8' into greasepencil-object

Conflicts:
source/blender/draw/intern/draw_manager.c

Use same rotation factor in both sides

Use fix UVs for solid stroke

If the stroke is solid, use fixed uvs to avoid any possible gap.

Extract Render code to separated function

Fix error in UV rotation when subdivide

WIP: Add UV rotation for Dot texture

Now the ramdom is fixed. Need parameters to adjust.

Add ToDo comment for fixing later
