Note that since the markup might exist for other reasons, it has
to be turned on with a preference setting. (It goes through a set
of bitflags so the same architecture can be used for other markup
structures that we might want to support in the future.)
Note also that this is more about engineering nomenclature than
visual formatting. In that respect it's more similar to overbar
than italic or bold.
deque structures have higher overhead than vectors. Not usually
problematic, but with hundreds of thousands of characters each with only
a few strokes, the overhead becomes dominant.
Be more intelligent about sorting lib tree items. (Footprint
entries, for instance, come out of an already-sorted list.)
Don't recreate menus twice when laoding Footprint Editor.
More pervasive use of WX_FILENAME to avoid expensive calls to
wxFileName::SplitPath() and string concatenation.
For POSIX kernels do all the work on the file-system side so we
don't have to keep converting back and forth between encodings.
Moved the code handling text overbars to a single function
(ProcessOverbars()) to replace similar pieces of code trying to do the
same thing.
Fixes: lp:1735906

Commit BZR 6703 introduced a minor horizontal adjustment for stroke
text rendering in GAL, but the Translate() call was done before
calling Save(). So, when this function was called multiple times a
residual offset carried over to each subsequent line.

* remove duplicate code between draw functions and STROKE_FONT used in GAL. Use only STROKE_FONT methods in draw, plot and test DRC function for texts. It remove slightly different shapes between GAL and other calculations.
* fix incorrect bounding box for texts with overbar. Especially noticeable for texts with overbar inside a copper zone in Pcbnew.
* fix a few minor other bugs related to graphic texts.
I tried to merge some constants used both in legacy mode and gal mode (which were, before this patch, separate constants).
There is still a serious work to avoid different calculation code for the same text in draw and plot functions.
Work in progress to merge these calculation functions.
these options are used in GAL mode, but the usercannot control this visibility. So if the board file does not have these visibility flags set, the GAL never show them.
Fix also a compil warning.
Moved scaling of font glyphs to the moment when they are created (eliminated a few multiplications unnecessary variables).
Changed some magic numbers into constants.
Removed a few unnecessary variables and fields from OPENGL_GAL.
Added function GAL::ClearCache() for freeing memory used by cached items.
Fixed a few memory leaks (tesselator, PAINTER's settings & VIEW_ITEM's groups).
Changed a few functions into inlines.
