This makes it easier to see which pins have alt modes
available. There is an option to turn them off.
The icon positions are chosen so they they shouldn't
interfere as far as possible:
* If the text is inside, the icon goes more inside
the body
* If the text is above/below the pin, it goes away from
the body
This means it won't collide with a symbol wall in
most cases, but some symbols with alt pins on opposing
sides may need to be widened if the icons are show.
Includes a rather fiddly refactor of the SCH_PIN painter
function, which needs quite a lot of massaging to allow
it to figure out where an icon would go. Quite a bit
of logic is broken out into smaller encapsulations with
less visible state to each chunk.
Icon modes for base-name-selected and alt-selected are
included, but only the former works due to information
being thrown away during the SCH_PAINTER tempPin
process.

Remove some useless spacers, and do not force some widgets to have a to
large size (by removing empty areas).
Work in progress: one panel is still too big.
Previous the cross-probing options were mixed between sending and
receiving cross-probe events. This clarifies so that all of the pcbnew
cross-probe options deal with whether the cross-probe is seen in pcbnew
and all of the eeschema options deal with seeing the event in eeschema.
Also updates the wording in the options panels to be the same where
possible and adds tooltips
Fixes https://gitlab.com/kicad/code/kicad/issues/11454
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
ADDED new option to set selection highlight thickness.
Also change selection shadow width constants to
make the selection thickness change less drastically
with the zoom level.
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.
Split antialiasing options out from display options. Move
antialiasing to common. Duplicate the rest of display options
for Eeschema.
Implement OnSelectGrid and hookup GAL canvas refresh to
SetPresetGrid.
Add Grid Settings... to View menu and move Show Grid from
preferences to View Menu to match Pcbnew.
