1) Don't fracture font glyphs when generating them; we're going
to fracture during triangulation anyway.
2) Don't check for self-intersection when deciding to fracture.
It costs nearly as much as the fracture does.
3) Cache drawing sheet text.
4) Use the current font when checking for cache validity.
5) Parallelize glyph triangulation.
6) Don't invalidate bounding box caches when offset by {0,0}
7) Use the glyph cache when generating text effective shape.
8) Short-circuit NormalizeJustification() if its center/center.
9) Don't triangulate for GuessSelectionCandidates()
10) Avoid sqrt whenever possible.
11) Pre-allocate bezier and SHAPE_LINE_CHAIN buffers.

Version 7 text alignment changed subtly for stroke fonts from version 6.
Additionally, the output has been different between screen and plotting,
leading to offset text in plotted output relative to the text shown on
screen.
This introduces a fudge factor in FONT::getLinePositions to correct the
offset in the plotting output relative to v6.
This also changes the SCH_PAINTER and PCB_PAINTER to correct the
relative offsets between GAL and PLOTTER classes. The source of these
offsets is atm unclear.

Many minor tweaks were added that changed the output of the stroke font
from v5/v6. These offsets changed the gerber output expected. This
reverts the changes to something much closer to the v6 output. It is
not pixel-perfect but gets very close on most texts.

While convoluted, this model matches as best we have found so far, the
alignment with scintilla. The spacing is character size for N-1 of the
characters in the 4-space tab stops. The final character is sized for
the actual space character in the stroke font (0.761905)

The overbar function in outline fonts recursively calls the text
function which already owns the lock. To avoid this, we have an
unlocked variant that is wrapped by the exposed text function

ttf fonts can declare multiple language names. Many by default opt to just declare one and not tag it any particular language.
However, there are CJK languages that typically leverage this function the most. They'll tag both a "en" and a cjk lang family name in CJK characters.
To be as user friendly as possible, we need to display said fonts in the CJK languages if KiCad to set to such a locale.

[Since 2.5.6] In multi-threaded applications it is easiest to use one FT_Library object per thread.
In case this is too cumbersome, a single FT_Library object across threads is possible also, as long as a mutex lock is used around FT_New_Face and FT_Done_Face.

LoadFont()'s only usage already checked for nullptr to fallback, let's actually return nullptr on a failed load

If the font face doesn't include a Bold or Italic version, we still want
to display the font as bold/italic, so we fake it with freetype.
This also prevents recurring error messages where the outline font warns
about "substitutes" within the same font family.
Also allows variants on the weight descriptor to be used without
throwing a substitution warning

We cache newstroke loading, but if we have threaded loads, we might ask
multiple threads to load the newstroke font at the same time. This
causes conflicts in the vector allocations->crashes
Also adjusts metrics to better match stroke font.
Also removes text-halo highlighting as it's too expensive to re-render
when the zoom changes.
Fixes https://gitlab.com/kicad/code/kicad/issues/11460
Also fixes a bug that we'd render too many glyphs when some glyphs
were combined. (To test, render "text" in Apple Chancery. The opening
"te" is combined into a ligature after which we render an extra 't' at
the end.
