Changelog:
- sfc/ppu/background: minor code cleanup and simplification
- sfc/ppu/background: $2106 MOSAIC register was implemented
incorrectly
- sfc/ppu/background: fixed mosaic effects in hires mode (temporary
fix)
- sfc/ppu/background: fixed mosaic effects in interlace mode [Cydrak]
Errata:
- sfc/ppu/background/background.cpp:48: should be
`if(!mosaic.enable) {`
Turns out there is only one mosaic size, and the other four bits are
per-BG mosaic enable. This matters a lot for hires/interlace, as
mosaicSize=0 (2x2) is not the same thing as mosaicEnable=false (1x1).
Although I've now implemented this, I really don't like how my mosaic
implementation works right now. I tried to redesign the entire system,
and completely failed. So I started over from v104r10 again and instead
went with a more evolutionary improvement for now. I'll keep trying.
Also, the combination of mosaic + offset-per-tile is still sketchy, as
is mode 6 offset-per-tile. I'll get to those in the future as well.
