Merge branch 'master' into modifier-panels-ui

Only rebuild panels when modifier list changes

Benefits of this:
- Epanding and collapsing modifier panels works
- Efficiency
- Solves other handler crashes

Also renamed modifier_index to list_index for more generality

Remove unecessary changes

Fix undo misdetecting identical future chunk in some cases

Clear is_identical_future before adding a next undo step, to avoid wrong
values for cases where we undo and then add a step with different changes
than what was previously the next step.

Ref D7274

Fix undo incorrectly detecting mesh as always changed after edits

Mesh writes a modified copy, which meant recalc_undo_accumulated was never
cleared on the actual datablock. Also clear mesh->runtime on write to avoid
detecting changes, since it's cleared on read anyway.

Fix undo debug logging not printing all types of undo pushes

Ref D7274

Fix T74547 EEVEE: Image texture crash with use after free

Merge branch 'master' into greasepencil-object

Fix T75144 Grease Pencil: Python generated strokes flicker and crash

Merge branch 'master' into greasepencil-object

Fix T74663 GPencil: Fills are Flickering on Nvidia

This was caused by an unitialized variable.

GPencil: Fix overlay blend mode creating inverted colors

EEVEE: Bloom: Fix inverted source and base buffer

This does not change the ouput much.

Fluid: Removed Empty Space option for liquid domains

The option only makes sense for gas domains where there is some density.

Fluid: Optimization for mesh file loading

Improved loading times for mesh files by reading bigger chunks of data from the disk at once.
