This speeds up build time considerably for these platforms compared to
using `lto=full`, which is sadly single-threaded with LLVM, unlike GCC.
Changes to default behavior of `lto=auto` (i.e. `production=yes`):
- Linux: Prefer ThinLTO for LLVM
- Web: Prefer ThinLTO
- Windows: Prefer ThinLTO for llvm-mingw
The following LLVM targets don't use LTO by default currently, which
needs to be assessed further (gains from LLVM LTO on performance need
to be weighed against the potential size increase from heavy inlining):
- Android
- iOS
- macOS
- Windows clang-cl
This restriction was added to fix#7373 back then, which was a symbol conflict
between FreeType's bundled copy of gzip/zlib, and distro packages.
But we also unbundled FreeType's zlib in #69395 so this is no longer an issue.
On the other hand recent issues pointed out that using system-provided icu4c
or harfbuzz can cause issues (#91401, #100301). We still allow it for now but
raise a warning.
Technical implementation notes:
- Moved linearization step to before the outset matrix is applied and
changed polynomial contrast curve approximation.
- This does *not* implement Blender's chroma rotation to address hue shift.
This hue rotation was found to have a significant performance impact.
- Improved performance by combining the AgX outset matrix with the Rec 2020 matrix.

Fixes some editor menus and option buttons requiring two clicks to open
by checking status.pressed_down_with_focus separately from other press
status flags. Makes all pressed statuses consistent on toggle buttons
with ACTION_MODE_BUTTON_PRESSED.
Before, we would check both methods together, leading to loops.
Now we track the actual reason we suspended and only unsuspend when
that same reason triggers. For example, if we suspend because of the
suspended flag we'll unsuspend only because it got unset. Conversely, if
we suspend because of a timeout we'll unsuspend only if we get a new
frame event.
We do this because, while some compositors properly report a "suspended"
state (hinting us to stop repainting), most don't and we need a "safety
net" anyways as we do not want to constantly stay at 1fps (the max time
we'll wait before giving up) either.
Corrected improper string escaping in the OS.shell_open() Windows path example. Backslashes are now properly escaped to prevent string parsing errors. Also, added a new alternative example of how to mount a Windows path with OS.shell_open().
