Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Our glyph bounds clipping test will fail for the first character of a
string if that character has negative left-side bearing. This is not
usual but can happen in some designs for lowercase "j" to have the tail
hook under the preceding character.

Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

NDEBUG is part of the C standard and disables asserts. Only this will
now be used to decide if asserts are enabled.
DEBUG was a Blender specific define, that has now been removed.
_DEBUG is a Visual Studio define for builds in Debug configuration.
Blender defines this for all platforms. This is still used in a few
places in the draw code, and in external libraries Bullet and Mantaflow.

Changes to FontBLF initialization so that the cached fallback fonts,
which remain faceless until needed, get all required setup.
Otherwise they are not kerned and we also don't get metrics from them.
Pull Request: https://projects.blender.org/blender/blender/pulls/114018
When loading a font, gather metrics and other information that can help
use it more correctly. Default weight and slant, X-height, cap height,
locations for underline, strike-through, subscripts, etc. Family and
style flags, etc.

BLF_width_to_strlen measures text with reduced accuracy with Hinting or
subpixel anti-aliasing enabled. blf_font_width_to_strlen_glyph_process
does not take into account these changes when iterating through glyphs.
Pull Request: https://projects.blender.org/blender/blender/pulls/113698
Separate user configuration of subpixel antialiasing from the hinting
options. For example, this allows turning this on while hinting is
"None", or off when hinting is "Full".

There should be no Subpixel AA if the user has deselected
"Anti-Aliasing". Render target FT_LOAD_TARGET_MONO is strongly
hinted to pixel grid and shouldn't be messed with.

Without this it was necessary to convert pasted text into spaces
for them to display properly.
Since tabs are a valid part of a string, it's incorrect to assume
tabs can always be expanded to spaces.
Pasted text and console output now display tabs properly,
the tab still uses spaces for indenting though.
Make type conversions explicit so it's clear when char/char32_t/uint
values are being mixed, also use int instead of size_t for cursor
functions because the cursor is an int - which caused many int/size_t
comparisons.
Slight corrections to embolden, mostly removing any vertical expansion
and better matching "wght" variable axis. Also improved comments for
all the glyph transform routines.

This makes it clearer other "safe" functions should be used in
combination with the resulting offsets.
Also correct doc-string which wasn't updated from the "or_error()"
version of this function.
