DRW: Fix facing reset when drawing with inverted camera

RNA: Fail makesrna if enum identifiers contain spaces

We could of course always add checks for more invalid characters, but
I'd say they are more unlikely to happen.

Fix compile error when building with Cycles

DRW: Support inverted view matrix

We detect the case where we need to invert the facing directly inside the
DRWView update and do the appropriate GL calls at draw time.

Fix T63047 Camera with negative scale works only in Cycles Rendered view
Fix T71352 Negative scale camera causes BLI_assert

Fluid: Temporary fix for gzopen on windows

Needs more consideration. This fixes compilation for now.

Theme: Radial gradient background and enum for gradient type

This commit replaces the "Use Gradient" checkbox theme option with an
enum and implements a radial background.

Whith this change, it should be easier to implemet other types of more
complex background types, like a world space oriented gradient.

Fix T54270: Reset last_hit and last_location when reading the file

It does not make sense to read those values when loading a file and they can crash the cursor if they contain invalid coordinates.

Fluid: Updated manta pp files

Updates in the files include:
- New manta files now use an platform independent gzopen function
- Adjusted argument name for vorticity

Fluid: Updated Manta updater script

Minor adjustments for the build directory location.

Cleanup: `make format`

Fluid: More cleanup in fluid rna code

Removed scientific variable names from UI.

Fix T73932: modifying keyframes in nodes fails when there is an image sequence

Image animation should not be an depsgraph node of type ANIMATION, there is
no need for it to be affected by the special casing for that.

Sculpt: Pinch only in the direction perpendicular to the stroke

By pinching this way, we can fix some artifacts when sculpting following
the topology direction. It does not make much difference with dyntopo/
remesher, but I think this should improve the quality of the brush when
working with Multires.

Fluid: Cleanup in fluid rna code

More descriptive names for secondary particle options.

Fix T74009: `bpy.ops.outliner.orphans_purge()` poll being too restrictive.

There is no reason to even require an editor at all here, for now just
kept the 'orphan view needed' condition for the outliner case only.

Fix for Fix (c) : Normals Edit modifier using unititialized array of normals...

Own mistake in recent rBcfdb5b9a8b07.

Fix T72751: Timeline crash from overridden scene.

Depsgraph RNA pointer would generate infinite loop in override comparisons.

Depsgraph pointer should never be considered here anyway, this is purely
runtime data.

Fluid: Fix typo that was made in 4453509d83dc

Fix T73770: Mantaflow is unable to bake fluid simulations on non-ASCII file paths

Some fluid cache functions were not using Blender's more secure BLI_gzopen() function. On Windows there are some special cases which this function can handle compared to the plain gzopen().

readfile: Move ID refcounting to libquery.

Having that extra ID users handling at readfile level, besides generic
one ensured by libquery, has been something bothering me for a long time
(had to fix my share of bugs due to mismatches between those two areas).

Further more, work on undo speedup will require even more complex ID
refcount management if we want to keep it in readfile.c area.

So idea is instead to generalize what we did for linked data already
when undoing: recompute properly usercount numbers after liblink step,
for all IDs.

Note that extra time required here is neglectable in a whole .blend file
reading (few extra milliseconds when loading a full production scene
e.g.).

Notes:
* Some deprecated data (IPOs) are not refcounted at all anymore, this
should not be an issue in pratice since the are supposed to get deleted
after doversion anyway.
* Refcounting happens after `do_versions_after_linking`, i.e those
functions won't get valid ID usercounts currently. Again, this is not a
problem in current code, if needed we could recompute refcount before,
and then ensure `do_versions_after_linoiing()` actually handles properly
usercount, which it does not currently.
