Question: I'm trying to understand the precision of the @gfx graphics system. Does it use 8-bit integer or floating-point arithmetic internally for blending operations (like gfx_a)? how does it handle very low alpha values, such as gfx_a=0.01, does it get truncated to 8-bit?

    You can refer to lice.cpp (link to LICE_FillRect, e.g.) for the drawing primitives... For gfx_a, that is passed as the 'alpha' parameter, which is indeed quantized to 8-bit, though more than 8 bits, as you can use out of range values, but yes quantized to the nearest value of 1/256th.

    Thanks man for the link. That custom 256 thing you did, brilliant. I have understood it now.
