GPencil: Cleanup - Make function static

GPencil: Use existing eval copy for single users

Merge branch 'greasepencil-refactor' into temp-gpencil-eval

GPencil: Fix previously selected strokes shows selected after lock their layer

GPencil: Refactor: Fix assert caused by framebuffer usage optimisation

GPencil: Optimize when use only one user

Merge branch 'greasepencil-refactor' into temp-gpencil-eval

GPencil: Fix versioning code to check version

Merge branch 'greasepencil-object' into greasepencil-refactor

Merge branch 'master' into greasepencil-object

GPencil: Fix segment fault in triangulation

If the number of points is < 2, clear the triangles data.

GPencil: Move triangulation to modifiers and remove force fill recalc

GPencil: Refactor: Allocate GPU framebuffers only if necessary

Also use signed format only if needed.

Note that you cannot see subtractive, overlay and divide blend modes in
the viewport because of the srgb hack AND the current viewport framebuffer
format.

Cleanup: Rename BKE_gpencil_calc_stroke_uv function to BKE_gpencil_stroke_uv_update

Calculate Filling data when stroke is modified

Instead to calculate the geometry data in runtime, now this data is calculated when the stroke is created or modified and saved.

Revert "Tag any stroke using the material property"

This reverts commit 07c2a935cfb17c1d4b13d715d6ede26b632c7447.

Remove gp_style parameter

Tag any stroke using the material property

This is required to calculate triangulation if the material is changed from NO Fill to Fill

Fixes after first code review

Create duplication of material array for eval datablock

If this copy is not done, when the datablock is cleared, the first datablock that use the material array, destroy the array, and in the second time the pointer is used, it's invalid.

Now, each datablock, uses its own material array.
