I have some questions related to CALayer drawing. I want to be able
to display images, text, 2D graphics or a PDF page. I'm able to
display an image by directly setting the contents property using a
CGImageRef or subclassing CALayer, overriding display and sending
setNeedsDisplay, but nothing I do seems to trigger the call to
drawInContext. I've tried using a delegate for the CALayer and
subclassing CALayer, but drawInContext never gets called. Is there
something fundamental that I'm missing?
Is the needsDisplayOnBoundsChange property set to YES on your layer?

I was under the impression that it didn't matter, but yes, I've
tried that as well.
