Alas, the arrow is a png that uses 200 different colors, plus has alpha channel information which I'm ignoring for now. Is XSetClipOrigin() also really slow, or could I get away with using it, given that I'm only updating the screen 30-40 times per second? I have yet to dip my toes into the Render extension, so if XSetClipOrigin() is "fast enough", then my application need have no fuss nor muss. > You mean in the pictures from his talk?

Is it true Xfree86 plans to support Sparc and HPUX platforms in the future, now that it is the "standard" X? >Render extension was a skeleton back then.

When you I ready a post in the archives; doing it that way may work now but is actually undefined behavior. Not kosher. Jonathan
