Hi,
I'm doing a sort of "brush" paint tool. Since this painting needs to
be composited onto another image, I subclassed an NSImageView, and
gave that mouseDown: mouseDragged: and mouseUp: methods that add lines
to my image using NSBezierPath.
Sadly, the drawing feels very jerky and unresponsive. Any suggestions
from Quartz Gurus on how I can improve this?
Did you remember to turn off event coalescing?
