When one draws a rectangle in a CALayer delegate, and the -drawLayer:: concatenates (and/or sets?) its own transform before drawing, when the layer has a transform, and the root parent layer has both a transform and a sublayer transform, and the host NSView has different bounds than frame, and there is resolution independence / interface scaling.....*deep breath*.....
This is starting to sound like "Fox In Socks"[1]: "When tweetle beetles battle with paddles in a puddle, they call it a tweetle beetle puddle paddle battle. AND... When beetles battle beetles in a puddle paddle battle and the beetle battle puddle is a puddle in a bottle... ...they call this a tweetle beetle bottle puddle paddle battle muddle. AND... When beetles fight these battles in a bottle with their paddles and the bottle's on a poodle and the poodle's eating noodles... ...they call this a muddle puddle tweetle poodle beetle noodle bottle paddle battle."Coordinate transformations give me fits, too. I've was having "fun" yesterday porting some of my code to an, uh, superficially very similar platform, whose coordinate system is for some reason upside- down (or is that right-side-up?) compared to AppKit's. :-P
