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
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
There is no reason to use case-sensitive path lookups on MS-Windows.
Also replace BLI_str_endswith with BLI_path_basename since ends-with
checks don't ensure a preceding path separator.
Loading a font in BLF would search a list of directory presets
however these presets were never used.
Remove them as all callers pass in full paths.
Also rename FontBLF::name to mem_name as it's only needed as an ID
for in-memory fonts (to prevent them being loaded multiple times).
Non-unique font loading now compares against the filepath or mem_name
when loading from files or memory (before both used `name` which was
often the filepath, sometimes the full ID-name).
- Rename name/filename/path to filepath when it's used for full paths.
- Rename name/path to dirpath when it refers to a directory.
- Rename file to filepath or path (when it may be a file or dir).
- Rename ImBuf::name & anim::name to filepath.
The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

When drawing text with multiple lines inside a frame node, depending
on the zoom level some lines would wrongly get clipped despite being
inside the clipping region.
This was caused by the clipping check in `blf_glyph_draw` not accounting
for the font’s aspect.
