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.

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.
There were enough cases of callers ignoring a potential the error value,
using the column width for e.g. to calculate pixel sizes, or the size in
bytes to calculate buffer offsets.
Since text fields & labels can include characters that return an error
from BLI_str_utf8_as_unicode, add the suffix to make this explicit.
It wasn't possible to select the position between two tab characters
with the mouse cursor in the UI. Don't handle characters with an unknown
width as combining.
Follow up to [0] which changed this for cursor motion.

The result of BLI_wcwidth wasn't checked before using the result to
calculate a width, this cause a negative return value to be multiplied
by the font size which divided by zero.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
The cleanup of blenkernel last weeks , caused the house of cards to
collapse on top of bf_gpu's shader_builder, which is off by default
but used on a daily basis by the rendering team.
Given the fixes forward in #110394 ran into a ODR violation in OSL that
was hiding there for years, I don't see another way forward without
impeding the rendering teams productivity for "quite a while" as there
is no guarantee the OSL issue would be the end of it.
the only way forward appears to be back.

The problematic commit was 07fe6c5a57
as blenkernel links most of blender, it's a bit of a link order issue
magnet. Given all these commits stack, it's near impossible to revert
just that one without spending a significant amount of time resolving
merge conflicts. 99% of that work was automated, so easier to just
revert all of them, and re-do the work, than it is to deal with the
merge conflicts.
