Cleanup: Change flag name, add comment

Clarify region size refreshing code in ED_screen_ensure_updated

Fix headers not using correct background color

Top-bar operator settings: Add simple "More..." button to show all settings

Doesn't make much sense yet, but it will once operator settings are
split into basic and advanced ones (see D2883).

Fix errors in UI scripts after last merge

Patch by @sergey, with minor fixes.

Rework tab data storing to fix glitches & get rid of hacks

Fixes glitch where hovering an active tab would make the tab appear like
a hovered non-active one.

Still not the most beautiful solution, but it's as good as it can get
with our current UI code I'm afraid.

Don't show redo buttons in top-bar if redo is not supported

Remove ED_area_global_initialize

Should be fine if global areas call ED_area_initialize now.

Fix small jumps of area rectangles and contents

Should also fix some glitches/jumping on HiDPI screens.

Most of this is related cleanup, actual fix is rather small (check
changes in screen_vertices_scale and WM_window_screen_pixels_y)

Add 'x' icon to active workspace tab to delete workspace

Icon could be a bit nicer, but is consistent with other places in the
UI. Code is also a bit hacky, as usual in interface handling...
