Local history combines project backup and autosave into a single place
where arbitrary history can be stored efficiently and restored to any
point in time. Git commits are made on a debouce timer to hold
modifications, allowing the user to step backwards in time to arbitrary
points. Restoring backups does not remove the existing files and
choosing to restore an autosave point does not remove the state of the
files prior to the restore, providing additional safety.
Keeps the maximum storage size limit but removes the additional
limitations of number of backups/backups per day, etc as these are not
relevant to a CoW-based backup as unchanged files do not take up
additional space.
Makes all canvases obey the same rendering parameter. Also keeps the
canvas selection with the anti-alias selection, which makes logical
sense. Reduce the antialias selection to a single choice rather than
two different choices for different canvases
Unlike the old "icon scale" (that actually scaled all bitmaps)
this one actually changes the toolbar size while making use
of the new bitmap bundle functionality
Add more resolutions for all tool icon bitmaps

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)
Moves the OpenGL AA options to the same Fast/Balanced/HQ options as used
in Fallback. Fast and Balanced are the SMAA options, with decreasing
threshholds and more processing in the balanced version. HQ is
supersampling x2. This takes more memory and may not work for HiDPI
screens with underpowered graphics cards. But it looks the best of the
three options.
The SSx4 option is removed as it added little benefit in either regular
or HiDPI screens

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.
