it used to leak GC's. but i remember fixing that years ago.

also the fact that those ruotines dont give you any alpha channels and arent
particularly optimal. if you have a cache the cache will fill up over time
(pixmap andimage) if you use this and sue different images, but then it will
level off when full. you can set the cache to 0 to disable this.

looking at the code he color modifiers will also cause the cache to fill since
the cached pixmaps arent valid with a new modifier. :)
