Avoid O(N^2) by spatial sorting, don't run checks if the bounding boxes
don't overlap.
A second copy is ordered by type to help classes that only want to check
a few types having to walk the whole list.
ADDED arc, circle and rectangle shapes for schematic. Shapes support
line styles and fill colors.
CHANGED sheet background color in Edit Text & Graphics Properties to
fill color (and it now affects shapes).
Pushed STROKE_PARAMS down into common and moved all shapes to using it
for stroke descriptions.
Simplify logic by adding quadrant-based BUS_ENTRY ctor.
Fix issue with bus entry size having been in mils rather than IU.
Fix issues with logic.

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.
Accessors were previously GetType() and SetType(), but this is a bad name:
These names are already widely used in code as accessors for a data type.
We do not set a data type, but a style, so use a better name (GetPlotStyle/SetPlotStyle).
plotter.h contains now only a header common to all plotters.
The code does not actually change, but it allows modifying a specific plotter
without recompiling most of kicad files.
ADDED Eeschema-specific netclass settings including wire and bus
thickness, color, and line style.
Netclasses override individual wire & bus colors and line styles.
If that proves an issue we might look at something more sophisticated
with inheritance.
