Only affects internal API, bout could be exposed as an option for
the compatibility reasons with other software.
Is a part of some ongoing development of multires, but might or
might not be used.
Support for showing images in background/foreground and only in perspective/orthographic view.
Internally the depth of the image is modified in the fragment shader by setting `gl_FragDepth` explicitly.
The UI still needs some work to improve usability, see D3863 for details.
Currently there is one duplicated function, not sure how to best deduplicate it yet. (`is_image_empty_visible`)

That way scripts can have a consitent way to get unique ID key/string,
and can use it for access in bpy.data collections as well.
Note that this kind of douples the old py API way of doning this
(passing tuple of (ID-name, lib-path) instead of just ID-name).
Also reshuffle a bit that whole code, did some renaming,
`BKE_id_to_unique_string_key()` is now using same base code (instead of
using whole library filepath...), etc.
It is caused by some sync issue apparently. Adding glFlush in these
two places fixes it.
Caveat: it might have a small perf impact (did not measure it).
The fix is limited to the affected driver/operating systems.
When enabled, inserting keyframes into F-Curves with simple cyclic
extrapolation (the same conditions as required for cycle-aware auto
handle smoothing to activate) will take the cycle into account:
- Keyframes that are being inserted outside of the cycle bounds
are remapped to be inside the cycle. Thus it is not necessary
to be within the main iteration of the cycle when tweaking.
This becomes especially useful in the final animation tweaking
phase when the channel keys may be staggered for overlap, so
the actual master period is different for different channels.
- Modifying one of the end points of a cycle also changes the
other end point when appropriate, to preserve smooth transition.
This feature applies to both manual keyframe insertion using
'I', and auto-keyframing.

Since we now have an Opengl "render engine", it is misleading to have this
operator still called "OpenGL Render" when all it does is take a snapshot
of the viewport.
This option allows to fade all layers except active one. This can help in very crowded scenes with a lot of layers, to verify you are working in the right one.
2.7x was displaying 2 additional subdivision for theses views. Bumping to 3
just to say we improved it!
Hypothetically it can be increased as much as we want but float precision
can quickly become an issue.
