Cleanup: remove unused interlace code after removal of fields.

GHOST/Windows: don't prefer swap copy method.

This is no longer needed with the new offscreen draw method, so use whatever
is default and hopefully fastest. Fixes console warnings in some setups that
don't have swap copy.

Fix Cycles standalone build issue with OpenColorIO.

Image: remove fields option for image sequences

Remove support for loading interlaced image sequences because
its less common now to record interlaced video,
the option to de-interlace video on load remains.

Fix for recent numeric input checks

WIP: More changes to try to get Draw tools

Still not working

Do not include object type in name for Brush enums

Fix T55826, fix T55804: crash after copying scene with linked objects.

Fix accidentally removed particle function in GLSL, still not supported though.

Fix popovers showing unnecessary titles.

WIP: Changes to make Sculpt and Weight paint tools work

This is a temp solution while we get the new toolsystem in place

Eevee: LightCache: Initial Implementation

This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).

The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.

There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.

Object Mode: Change Lightprobe display.

DRW: Add new features from lightcache branch

- Change gl_context_mutex to a ticket mutex ensuring interactivity even
when rendering.
- Add DRW_custom_pipeline for using DRW outside of the viewport and render
pipeline.
- DRW_opengl_render_context_*** and DRW_gawain_render_context_*** to use
with DRW_custom_pipeline.
- Add possibility to bypass deferred compilation on demand (not User
demand).
- Add union to access DRWMatrixState members more easily.

DrawData: Change drawdata to a generic struct shared accross ID types

This makes tagging much more generic and make the world updates more in
line with the new tagging system (Depsgraph).

GPUTexture: Refactor of texture creation & new feature

- Texture creation now requires explicit data type.
- GPU_texture_add_mipmap enable explicit mipmap upload.
- GPU_texture_get_mipmap_size can be used to get the size of a mipmap level
of an existing GPUTexture
- GPU_texture_read let you read back data from a gpu texture.

Numeric Input: remove fake-editing option

Numeric input allowed mix of editing and hotkeys which were interpreted
as modifiers instead of using as numeric input.

This meant entering '1.0*3' needed to be typed as '1.0**3'
('*' to activate, and again to multiply).

Pressing '/' gave the reciprocal of the current number
which could be useful.

Test removing this feature, so only full numeric input is supported.
