The wording is admittedly wrong, but I find yours confusing. What about
These are like draw_sprite(), but they additionally flip the image
vertically, horizontally, or both, respectively. Flipping vertically
means that the y-axis is reversed, while flipping horizontally means
that the x-axis is reversed, between the source and the destination.
This produces exact mirror images, which is not the same as rotating the
sprite (and it is a lot faster than the rotation routine). The sprite
must be a memory bitmap.
instead?
