Ternary logic
Compute "ternary logic" using an 8-entry lookup table.
For each bit, the expression will be computed as:
a |
b |
c |
lut |
|---|---|---|---|
0 |
0 |
0 |
lut & (1 << 0) != 0 |
0 |
0 |
1 |
lut & (1 << 1) != 0 |
0 |

lut & (1 << 2) != 0 |

Example
// if sprite_mask { background } else { sprite }
background.ternlog(sprite, sprite_mask, 0xe4)
