--- Comment #6 from wolthera <[email protected]> ---
I can't tell you about GIMP, but MyPaint just does it's normal blending mode in
integers:

https://github.com/mypaint/mypaint/blob/master/lib/blending.hpp

(fix_15_t is a uint32_t and fix_15_t_short is a uint16_t)

https://github.com/mypaint/mypaint/blob/master/lib/fix15.hpp

I am not sure what benefit it has to us to use this method anywhere but in the
normal/over/general lerp, but for normal/over/lerp it might actually be very
useful. The real question I suposse is if this issue is problematic enough in
16bit to have it there as well. (the float spaces don't need it, because well,
they're floats)
