GPencil: Fix damaged Overlay panel in Vertex Paint mode

GPencil: Fix damaged Overlay panel in Vertex Paint mode

GPencil: Refactor: Edit Mode: Add support for minor features

Add support for stroke color, vertex opacity and show stroke endpoints.

GPencil: Refactor: Fix multiedit having less predecence than onion skin

GPencil: Refactor: Disable GPencil Outline in edit mode

GPencil: Refactor: Edit Mode support.

GPencil: Refactor: Fix old implementation crashing on startup

GPencil: Refactor: Replace Stroke Miter break by rounded corners

Also fix stroke ends being twice too long.

GPencil: Refactor: Add outline overlay

This does not work correctly on square & dot strokes.

Also another issue is the depth blending. We need to fix the depth of
the outline geometry to match the 2D projection we do in the gpencil engine.

GPencil: Refactor: Move vertex shader logic to gpencil_common_lib.glsl

This is to be able to reuse the code in other engines/shaders.

GPencil: Refactor: Use drawcall matrices instead of custom one

GPencil: Refactor: Move batch cache functions to DRW module

This is in preparation of drawing the overlays.

Change message in case of pointer collision to always print.

It is very difficult to test that code, as pointer collisions are
expected to be rather rare... So for now systematically print when we
detect one, could be at least a useful hint in bug report.

And some more comments.

Cleanup: GPencil: Move GP_MATERIAL_BUFFER_LEN define to a common place

GPencil: Refactor: Move iterator to BKE
