For the RGB hires look-up table:
- extended to include the previous video byte's high bit
- so it's now: {previous high bit + prev 2 video bits + next 2 video bits} & current byte
For all the RGB look-up tables:
- reduced from 512 to 256 lines (only 256 were being used, so it was just wasting space)
Refactored CopyMixedSource():
- fixed the Rainbow demo (#627)
- sped up in Debug config
Bumped version to 1.28.3.1.
