Don't accidentally flip the x-axis glyph size when resetting after
a sub- or superscript.
Special-case three tildes in a row. (We could also do this for
sub- and superscript, but does anyone really need a superscript
^ or a subscript?

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.
Previously, a 600 DPI was used to set device scale (can create minor visible rounding issues).
Using now 4800 DPI to reduce these rounding artifacts.

It was due to a angle normalization between -360 and 360 degrees.
So, in arcs, if the start angle and end angle diff is n*360 deg,
this normalization gives start angle = end angle.
The fix forces end angle = start angle+360deg in this case.

This allows a const BITMAP_BASE to expose const image
data. This is currently done with const_casts, which is
"OK", only as long as the source image is not declared
const, in which case it's undefined behaviour.
Also immediately dereference the pointer to a reference
if it's not checked to make the non-null requirements
explicit at the point of access.
Move repeated GAL config reading routines into GAL_DISPLAY_OPTIONS.
THe app-level config is in here already, do the same for the
common config.
This means that the configs are loaded consistently, which fixes
the symbol-chooser preview window, which previously didn't use the
same config routine as other GAL canvases.
Future work could move these functions to free functions that
act on the public interface of GAL_DISPLAY_OPTIONS to avoid
GAL_DISPLAY_OPTIONS having to know about wxConfig and wxWindow.

Both Cairo and OpenGL had issues (different, though) with circles that are
thicker in line width than they have radius. This corrects the OpenGL
implementation (radius is calculated to the outer edge) as well as Cairo
(line width needs to be clamped to twice the radius)

First, add automatic detection of toolkit DPI scaling options. For now, this
is, in order,
* Check the GDK_SCALE option under GTK+ (users can set this to force the scaling)
* Check the value from WX's GetContentScalingFactor(). This will start to work
correctly from WX 3.1 and GTK+ 3.10.
Then, add a user-settable override in the main prefs panel, next to the icon
scaling. This is independent of the icon scaling options.
DPI handling is performed in a standalone class, so they can be shared between
the prefs UI and the OpenGL backend easily. Also means Cairo could use the same
interface in future.
Also adjust the OpenGL grid drawing code to use the computed scale factor,
which avoids over-thick grids in scaled environments (the user can manually
thicken the grid if wanted).

In Symbol editor, axis are always shown. However after switching the backend, axis were no longer drawn.
In Cairo engine, fix a bug preventing axis to be shown.
Each dot is an integer number of pixels wide, so supporting 0.5 width
steps no longer makes sense. We round up the existing settings to the
nearest integer and only allow integers in the dialog.

We shouldn't adjust the pixel size of the grid based on alignment in
GAL. This creates artifacts on the screen at different zoom levels.
The pixel width is fixed by grid size preference

Arc pixel adjustment needs to be limited to +/-1 pixel. But making this
adjustment to nearby points and then using the projection to correct the
center point accumulates errors that are large for angles near 0 and
near 360. This is a compromise that aligns _most_ arcs and provides
stable generation for all angles.

And filled but we don't use those yet. No pixel-alignment needed for
stroked semi-circles (I think) as we set the pixel width to be 1
regardless of the zoom level.

Pixel alignment is not required for track outline mode. It creates
differences between segment and radius calculations.
Also add specific width of the outlines
