I have to say, this is a pretty badass and fully-featured sprite class. Looks really good. I was going to harp on your pixel-perfect collision check but I was mistaken and it's actually very good (I didn't see it first that width and height were being set from the smallest of the two sprites).
Looks tried and true. What about the various classes this references, like a Logger and PixelGrabber?
Thanks. I know that width and height stuff in that method may be a bit unclear, maybe I've should have cleaned it up a bit before releasing it?
Also, Logger and PixelGrabber (as well as all other imported classes) are part of the JDK (as Riven pointed out)
