Fix T74417: Freestyle render removes image texture users

This simplifies freestyle render pipeline integration so we don't have to do
much manual ID user management at all. The complexity here was legacy from
Blender Internal.

Based on fix provided by Sybren A. St�vl.

Fix T74711: tiling brush option in image editor not working anymore

This makes it work again at least for the non-UDIM case. For UDIM it's not
great still but I'll consider that a known limitation. A proper solution is
probably to find the closest tile at the start of the stroke and then only
paint in that one tile for the rest of the stroke.

UI: rename image source Tiled to UDIM Tiles for easier discovery

Fix T75090: crash with old NVIDIA drivers after overlay refactor

Work around GLSL compiler bug with backslash in preprocessor macros.

The threshold only must be vsisible in Segment mode.

GPencil: Fix unreported missing parameter for Cutter tool

Fix error after recent change when WITH_INTERNATIONAL=OFF

Always need to install font files now.

Cleanup: typo in print

UI: remove non-unicode font and simplify default font loading code

There is no need to have another font embedded in the Blender executable, we
can assume the bundled font exists. In the future we may provide a fallback
if the font specified by the user in the preferences is missing a character,
but that can use our bundled international font.

UI: always use international font

This means Blender can display more text correctly without having to enable
user interface translation. Previously the quality of the font was lower,
but that has been fixed now.

The font files have now been ungzipped, which results in faster file loading
as Freetype can read only the parts of the file that it needs. Blender download
size should not increase since the release package is compressed.

This includes improvements for Cyrillic characters from the latest DejaVu
Sans fonts from D6960, contributed by Harley Acheson. Fixes T74097.
