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.

Cleanup: More use of LISTBASE_FOREACH

Cleanup: Use LISTBASE_FOREACH

Fix bug introduced in previous commit checking number of users

If the eval is not used for 1 user, the modifier is added again and again.

To avoid this eval, it would be required a flag to check if the modifier was applied before, but this need more work and we will do in the future.

GPencil: Show overlap option for Texture materials

Do not create eval data if users is 1

If only one user, the default eval data is used and don't need a new copy
