The resource fork in the Director 4 projector has a 16-color palette
right next to the 256-color System - Mac one, and the colors seem to
match the default System 4 palette. Nevertheless, this palette appears
to be reasonably different (both in colors and ordering) from the one
actually used. Included is a palette determined empirically from
DOSBox screenshots.
All of the builtin palette lookup tables have been reversed, to match
the original layout of the tables in the Director 4 projector executable.
This corresponds with the colour indexing used in Lingo.
Likewise, the code to load palettes from the cast no longer reads the
colours in reverse order, and shiftPalette no longer expects
the start index to be after the end index.
DirectorEngine::transformColor still exists to upgrade to 32-bit colour,
but no longer reverses the palette index.
The missing builtin 16-color palettes from Director 4 have been added.
