These are images used to display the splash screen and About box image. The *-master.svg
files contain text and rely on the presence of the fonts that are used in the images
(BankGothic for Wingware logo + tagline, and ChalkBoard for the copyright). When these are
edited and saved, the 100% vector copies must be created by selecting all objects, using
Object->Path, and saving to the name without -master' in it.

Files with no extension are bzip2 compressed svg files. They're renamed and compressed
copies of the non-master svgs that are created by the 'templates' build target because
some versions of macOS (at least the initial release of 10.15) would report that the
application developer could not be verified if the about box / splash screen .svg files
were included in the .app bundle.
