If the sprites are any multiple of 8 in width you shouldn't plot them with a
normal sprite function, even if you want to scroll pixel-by-pixel. Plot your
sprites (by yourself) into a buffer that's one sprite too wide and one sprite
too high, then copy-and-shift that buffer onto the LCD.

A Thaum is the basic unit of magical strength. It has been universally
established as the amount of magic needed to create one small white pigeon
or three normal sized billiard balls.
