Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good. Fast AA
in accelerated canvas uses SMAA with tweaks suggested by David Beinder.
Good AA is super-sampled x2.
Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves. Best is removed as it mostly affects text rendering
and not line drawing (as our text is)
Fixes https://gitlab.com/kicad/code/kicad/-/issues/8522
Conservative makes SMAA usable in Eeschema through weaker AA.
Aggressive reduces some artifacts compared to the High preset.
Restores the unused Ultra preset in the shader source to its original state.
You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
CHANGED: Settings are now stored in versioned sub-directories
ADDED: First-run dialog for migrating settings from a previous version
CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files
CHANGED: Color settings are now all stored in a separate settings file
CHANGED: The symbol editor and footprint editor now have their own settings files
CHANGED: Color settings are no longer exposed through BOARD object
CHANGED: Page layout editor now uses Eeschema's color scheme
Settings are now managed through a central SETTINGS_MANAGER held by PGM_BASE.
Existing settings will be migrated from the wxConfig format on first run of each application.
Per-application settings are now stored in one class for each application.
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.

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).

Cairo supports antialiasing when rendering but can be slow when set to
sub-pixel mode. This bumps the minimum version of Cairo to 1.12
(available in 14.04 LTS as well as mingw) to support three antialias
settings (fast, good, best) that offer speed/appearance tradeoffs.
This can provide a higher-quality eeschema render as it works on a
per-element basis as opposed to the OpenGL per-screen antialias.
The motivation here is to concentrate display options in the GAL display
settings, ready for removal of legacy canvases. Instead of having the
property as a member of the DRAW_FRAME, with the GAL canvas retreiving
it from there, it is now in the GAL_DISPLAY_OPTIONS struct, and both GAL
and legacy get it from there.
The options for setting cursor shape are then moved out of the general
options dialog, and into the GAL display options widget, where they can
be used in all GAL-aware programs.
GAL cursor shape works on GAL, but not legacy, so the option is now
available on OSX (but only affects GAL, and is labelled as such).
A new items is added to the GAL display options (and the dialog), and a
hotkey (Ctrl+Shift+x) is added to toggle it.

When reading config options from files, it's important to make sure the
value makes sense - the incoming data could be anything, and may have
incompatible values or be otherwise unreliable.
This introduces a simple way to define and use "mapping tables" which
can map between a "native" value, probably an enum (but not necessarily)
and some external value, for example the value written to file.
This provides a decoupling between the two values, as well as sanitising
inputs and outputs. This is important, as over time, if there isn't a
decoupled interface, changing options result in corrupt configs, or a
proliferation of obsolete enum values kept for compatibility.
GAL_DISPLAY_OPTIONS_OBSERVER aren't deleted by a base class pointer -
they are an "incidental" part of other classes. Add a virtual protected
destructor to make this explicit.
This allows the user to set a thicker grid line without causing the
grid lines to become over dense, or just make the grid denser according
to preference.
The term "density" is modified to "minimum grid spacing", which is
the pixel spacing between adjacent grid lines.
The spacing settings now comes in along, with other GAL display settings,
as part of GAL_DISPLAY_OPTIONS observer functionality. To this end, the
setter in GAL interface is removed, as an external user should be
setting this parameter via the GAL_DISPLAY_OPTIONS interface.
This adds a user-settable control for the grid line thickness on GAL
canvases to the display options dialog.

This puts the graphical/display options with the other similar options
in that dialog, rather than with the dimension options found in the Set
Grid dialog, which is in the Dimensions menu.
Also place the option itself in the GAL Display Options structure, so it
can be updated using the observer mechanism there.
The setter for the style in the GAL interface is removed, as the public
interface for setting this option is now to modify the
GAL_DISPLAY_OPTIONS structure and notify the GAL when done.
