Fix potential crash with Eevee render of missing image textures

This NULL check is needed elsewhere, do it here as well.

Fix Eevee shader node error when using both RGB and vector curve nodes

Fix crash in some Eevee shader node setups after vector math node changes

Cleanup: remove WITH_EMBREE make deps option

No other default enabled libraries have an option either.

Cleanup: Silence warnings

GHOST: Init New Windows with a closer theme color

The user theme is loaded after window creation so we should create the
window with a color that at least matches the default theme.

Fix T73763: Laggy when zooming a node editor with International Fonts

Two main reasons for the lag:
- Allocation of memory with transfer to GPU.
- BLF_cache_clear();

The (partial) solution is to avoid memory allocating in some setups
through the `GPU_texture_clear`.

GPU: Add GPU support to fill a texture image with a constant value

This solution is optimized for GL version 4.4 or greater.

Transform: Deduplicate time snap code

Cleanup: work around clang-format differences between versions

Ref T73747

Cleanup: fix compiler warning

Fix macOS build warnings about Boost symbol visibility

The default in Boost changed from global to hidden, but other libraries do
not use hidden symbols which gives warnings at link time on macOS.

Fix T67924: transform right/up arrow keys not working on macOS

Build: use clang-format from precompiled libraries for make format on Linux

Ref T73747

Build: enable Embree by default for make deps

Ref T73819, T73778

Keymap: Add front/back Alt-MMB absolute view axis switching

Oversight in previous commit.

Keymap: move weight & vertex paint handling before pose mode

This is needed so pose keymap doesn't override weight paint,
which currently prevents the weight paint context menu from showing.

Logically pose mode is secondary when used in combination with
weight paint, so evaluate it afterwards.

Also move vertex paint keymap since they have a lot in common,
it's simpler to keep them evaluated at the same place.

Resolves T73384

Cleanup: duplicate calls to add keymap handlers

Fix warp modifier invert vertex group duplicate flag

Fix T58571: Limited dissolve ignores boundaries between delimited faces

When a vertex between two edges is being collapsed,
it's important that edges between delimiting faces use the
angle between edges without scaling it down.

While faces with different materials wont ever be merged into a single
face, all the detail between the two faces may be removed.
