Each profile has a fixed number of *layers* with a predefined meaning. During

On fx-9860G, the vram is either monochrome or 4-color gray, so pixel colors can
only take 2 or 4 different values. This makes logical operations a privileged

## Logical operations on pixels
As a reference, here are the logical operations used to blit layers on past and
present versions of bopti. The $`x`$ parameter is a boolean; the transformation
must happen iff $`x=1`$. The significance of $`x`$ appears when extending the
present versions of bopti. The `x` parameter is a boolean; the transformation
must happen iff `x=1`. The significance of `x` appears when extending the
logical operations to a longword: it allows controlling 32 pixels individually
while still using only a couple logical instructions.
