The Avalonia app applies the colour scheme saved as ActiveColorScheme in
the shared user-settings file when the main window opens, and recolours a
nest's drawings from it when opening the nest, as WinForms does.
The plate canvas draws the background, sheet, edge spacing, etch, part
outlines and selection from the active scheme through SkiaSchemePalette,
a cache of Skia colours rebuilt when the scheme's colours change, instead
of hard-coded colours. Part outlines follow the scheme's outline colour
or the fill darkened as WinForms darkens it. There is no Options screen
to change the scheme yet.
