Cleanup: always use CLOG in names

Cleanup: remove unused function

Line Art: file r/w pointer clean-up for collection->object_cache_instanced.

Merge remote-tracking branch 'origin/master' into lanpr-under-gp

Collections: Use collection icon for collection color squares

Rather than using a fixed square, draw the filled collection icon. This
looks cleaner, and has the benefit of implying that collection colors
only apply to collections, not to objects or other types.

Outliner: Expand modifier panels when clicked in outliner

With properties sync, it makes sense to expand the modifier in the
properties editor on click, otherwise it takes an additional click to
make modifications to the modifier.

Cleanup: Formatting

Cleanup: Refactor parent bone into shared function

Custom Menus : fix minor bugs

Collections: Use 8 colors for color tagging

Property Search: Search in pulldown button RNA enums

This introduces a memory leak when accessing the enum items.
I'll solve that later.

Property Search: Search based on label buttons

Merge branch 'master' into property-search-ui-v2

Use panel custom data

Very unstable, and the delete button doesn't work. It's probably
best to just expose graph_panel_context and the equivalent NLA function.

Fix usemtl line not being written.

`==` ? `!=` : the bug.

`totface` ? `totpoly`: it was a mistake.

Rest is cleanup.

Finished bringing light tree code up to date

Use function pointer; remove redundant variables.

Post Review: Doc and comments and minor correction

Merge branch 'master' into greasepencil-object
