/*
Info:
- Extra samples for AA are stored in their own micro-tiles
Macro-Tiling:
- Contains one micro-tile for every combination of bank/channel select
- Since there are 4 bank and 2 pipe bits this means 4*2 = 8 micro tiles (or 8*4 for thick?). But the arrangement varies per tilemode (aspect ratio)
Allowed layouts: 1x8, 2x4, 4x2
- Address format: .... aaaaabbc aaaaaaaa A = offset, b = bank, c = channel
- Channel/Bank bits are determined by:
channel0 = x[3] ^ y[3]
bank0 = x[3] ^ y[5]
bank1 = x[4] ^ y[4]
