LineArt: Use array for lineart_push/append_points.

Cleanup: Use const for function arguments

LineArt: Use ICON_OUTLINER_COLLECTION for collection icon

Fix T82417: Panels draw below others while animating after drag

This adds a new runtime flag for panels that is set during the entire
drag and animation operation. The flag is set recursively so that
sub-panels know to draw on top too.

Note that this also replaces most of the fixes in 1960b8a361ee and
8e08d80e52d6 (D7462) with a more "built-in" solution.

USD importer: renamed files.

Renamed usd_reader_transform and usd_reader_object files
to usd_reader_xform and usd_reader_xformable, respectively.
Updated includes to reflect new file names.

USD importer: new USDMeshReaderBase class.

Moved read_mesh() function from USDXformableReader
class to new USDMeshReaderBase class.

Cleanup: Simplify panel collapse handler logic

Cleanup: Remove unused Panel.snap from DNA and handler code

This was a remnant of floating panels from the horizontal layout in
pre 2.5 horizontal panels.

Cleanup: Remove unused drag scaling code for panels

This is done more universally now, and this implementation of this is
no longer used.

Cleanup: Make panel function static

These functions were not used elsewhere, and the handling for the panel
tabs should be kept local to this file where possible. Also remove
another unused function and removed an unecessary "_ex" function.

Cleanup: Move function to proper file

This lower level drawing function didn't make sense in the panel code,
especially when it is used in multiple other places.

Fix T80313: Fix clipped text in splash screen on hiDPI monitors

The current layout gave too little space for the full "Search" string inside
the button.
Fix this by making sure radio-buttons have their text center aligned by default
in pop-ups too, like they do anywhere else.

This does affect a few other cases, e.g. the "RGB"/"HSV"/"Hex" radio-toggles
for color pickers. But this should be fine, I don't think they were ever
intentionally using left-aligned text (while similar buttons outside of pop-ups
didn't).

Cleanup: Improve property search related comments panel code

The comments related to property search changes should be generally
more correct and more helpful.

Renamed USDTransformReader to USDXformReader.

Cleanup: Use LISTBASE_FOREACH

Renamed USDObjectReader to USDXformableReader.

Miscellaneous additional cleanup, including function
naming convention.

UI: Replace uses of "loc/rot" with full words

Use "Rotation" in place of "Rot" for the rotation header text.
Cleanup various RNA titles and tooltips.

Cleanup: Remove incorrect comment

This function for replacing a button pointer in button groups is
needed by the block update from old code, so it cannot be removed
like its layout equivalent.
