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.
Differentiates better between the EDA_ITEM IsModified(), referring to
items themselves changing and the EDA_SCREEN IsContentModified(),
referring to whether we have made any unsaved changes.
Initialized COLOR4D takes an EDA_COLOR_T enum but then referenced it as
an index to the color table. This uses the enum as comparison against
the table-stored enum.
Adds standard orange to picker swatches
ADDED Paste Special... action in pcbnew
CHANGED Additional options for Paste Special... in eeschema, including
"Assign unique reference designators to pasted instance"
CHANGED: Environment variables defined outside of KiCad will no longer
be saved in the settings file. Paths can be configured via
the Configure Paths dialog and those changes will be saved in
the settings file if the new path is different from the default
and the path variable was not defined in the system environment.
wx/wx.h includes all wxWidgets .h files, and sometimes creates collision
names in #define between kicad and windows headers
Moreover, blindly including a lot of useless files is compil time consuming
Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
