draw it at different subpixel positions with a GPU, you will get
either the exact same result (if you use point-sampling on the
texture) or linear filtering. Linear filtering will cause a sub-pixel
positioned bitmap to blur further, causing a visible desharpening
positioned bitmap to blur further, causing a visible de-sharpening
of the character. (And, since the character wasn't hinted, it was
already blurrier than a hinted one would be, and not it gets even

You can avoid this by caching multiple variants of a character which

filtering, there is a better approach than caching several independent
positions, which is to allow lerping between the versions to allow
finer subpixel positioning. You can achieve these by interleaving
each of the cached bitmaps, but this turns out to be mathematically
