Fix T84345: Transforming the cursor fails with absolute grid-snap

Absolute grid snapping was using the pivot, which doesn't make sense
when transforming the cursor.

DrawManager: High quality normals for non meshes

This adds high quality normals for non meshes. These include

* Volumetric Object Wireframe
* Metaballs
* Extracted Curves
* Curves in edit mode

This is in preparation to fix a regression in recent AMD
drivers where the `GL_INT_2_10_10_10_REV` data type isn't
working in Polaris cards.

Fix T84106: attribute mix node worked incorrectly on float attributes

Merge branch 'master' into temp-gpencil-interpolate

Merge branch 'master' into greasepencil-object

Fix imbuf.new & resize allowing zero & negative dimensions

Cleanup: remove unused optional argument to imbuf.new

While this didn't cause any problems, it was incorrect.

Fix T84191: remove python API limits for Image.scale() dimensions

Since the introduction in 2c23bb838979131667c922df1f01738e02e6ca16,
these were set to 10000 each.

This seems like an arbitrary limit (BKE_image_scale / IMB_scaleImBuf
don't have limits and I couldn't spot similar size restrictions in
image relating functions), now match what we do for creating images
(rna_Main_images_new), use INT_MAX.

Fix crash reading files with unknown modifier ID's

Missing NULL check for the modifier type.

Fix early exit check in BKE_appdir_app_template_has_userpref

Logical error in 84f21c170dda9e503de440c20bc2753002987901
This check was a no-op, replace this with a check for an empty string.

Fix clang_array_check checking utility

Use python3 which is now supported,
only use CLANG_BIND_DIR & CLANG_LIB_DIR when they are set.

Also add immediate mode GPU API function calls.

Cleanup: correct array size in argument

Cleanup: use const variables

Cleanup: typo in c484b54453e6072399dd79daccf237bb4bd73b41

Cleanup: add NULL check for filename argument which could be NULL

While it's never NULL at the moment, checks elsewhere in this function
support passing in a NULL filename, so keep this working as intended
in case RNAProcessItem.filename is NULL in the future.

Cleanup: redundant call to WM_modalkeymap_find

Cleanup: redundant code, minor inconsistencies

- Remove ternary operators when both values are the same.
- Remove break after return.
- Remove redundant NULL checks for code which handles
those cases immediately beforehand.

Cleanup: use ARRAY_SIZE when when looping over the array indicies

Cleanup: remove self-assignment

Use CLAMP_MAX to remove redundant comparison.

Cleanup: remove redundant code

Fix for T62504 missed removing return call.
