The palette didn't fade all the way to white when using the
shrinking machine, which caused visible glitches. I've verified
against a YouTube "Let's Play" that in the original it did fade
all the way. Whether or not it did it in this exact way I do not
know, but... close enough.
This is used later when restoring savegames
- Rename V_RING5_PULLED to V_RADIO_ENABLED
- Implement Palette::fillBaseBlack and use it in Scene2803Small
- Fix Scene2802 (show disabled radio if it's not enabled)
- SpriteResource and PaletteResource resource classes
- Extend BaseSurface to be able to draw SpriteResources onto it
- Implement Entity base class (this may need some work concerning the update/message callbacks later since I'm not sure if the way it's done now is portable)
