Fix compiling with Blenderplayer

Prevent problems when appending scene with referenced proxy

Such a "referenced proxy" could be a proxy that is used in a constraint on
another object. Brings back part of 1cdc54dc7db85766 but without the
memory leak.

Usual UI/i18n tweaks & fixes.

immediate mode: small cleanup on timeline

(no need to unbind/rebind the same program)

Fix: Grease Pencil palettes were missing a RNA path callback

Proxy appending: re-establish link to proxies when they are made local

This allows appending of an entire scene from another blend file into this one,
even when that blend file contains proxified armatures.

This replaces the approach from commit 1cdc54dc7db85766.

Thanks @sergey for the help.

Fix T49635: column_flow Layout - last column is too small.

Column flow layout was abuse ui_item_fit in a weird way, which was
broken for last column items.

Now rather use own code, which basically spread available width as
equally as possible between all columns.

Cleanup: UI layout: remove unsed and confusing parameter.

Things are complicated enough like that, no need to add useless noise on
top of it!

inform immediate mode when switching OpenGL context

Longstanding to-do is now to-done.

Heinous bug reported by @dfelinto pushed me to fix this.

Gawain: fix immediate mode for multiple GL contexts

New functions activate & deactivate immediate mode. Call these when switching context and the internal VAO will be handled properly. VAOs are one of the few things *not* shared between OpenGL contexts.

Fix for crash on dopesheet drawing with immediate mode (rB7a552612c)

viewport: bring the manipulators

Fix timeline break after recent immediate mode change (rBf6e7e46f)

gawain: assert for immBeginAtMost(..., 0)

Draw depth even when in wire mode (for OB_RENDER)

Note: this is not working at the moment, but the logic is sound.
Since we will still change the drawing code a lot I think the commit is valid.

immediate mode: use new ThemeColor functions

gawain/immediate mode: new util functions for color uniforms

wrong alpha set for timeline theme (fixup for rBf329ebe3)

Immediate mode: timeline (keyframes and range)

Part of T49043

Fix T49631: radial control operators not using DPI properly.
