Fix T58101 : Image empties are only rendering their border when using MSAA

Texture Paint: fix fast selection update to also work without modifiers.

If there are no (non-deform) modifiers, the evaluated mesh simply
shares arrays with the base COW copy instead of having CD_ORIGINDEX.

GP: Fix line primitive when using to square behaviour

Previously the shift key for line primitives only allowed diagonals.
This change allows the line to constrain to vertical and horizontal lines.

Fix texture previews not updating when parameters are changed.

Partial fix for T58113 bevel harden normals bug.

when using a hardening mode in the bevel modifier.
