ZOOMSPRITE num%, x%, y%, relx#, rely#
A sprite image will be drawn to the back buffer. You can use the same image num% multiple times to draw multiple copies of the same sprite.
Scales a sprite image horizontally by relx# and vertically by rely#. The center stays the same as it was when using DRAWSPRITE.
If you put negative values for the relx#, rely# factors (e.g. relx#=-1) you can mirror the image.
