Add direct handling of quadratic beziers to save compute time and number
of points. Update cubic interpolation to reduce number of points
generated for a given smoothness
Cache data on open and used cached data to avoid multiple re-calcs
Remove minimum line length and number of segments and replace with
standard max error level. Allows us to specify the tolerance of bezier
interpolation
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.

* Add compare method to COLOR4D object.
* Add unit test to validate COLOR4D comparison method.
* Add missing color test in text attribute comparison method.
* Add unit test for text attribute object.
* Remove unnecessary headers from text attribute header.
* Move text attribute code into separate source file.
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.
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

Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.
