I'm trying to use scaling of the superlayer to implement a zoom
feature in my CAD app. The various elements in the canvas are drawn by
a CALayer subclass I have, which overrides drawInContext:. After the
zoom finishes animating, I want CA to call all the sublayer's
drawInContext: methods as necessary to re-render the layer's contents.
Is there any way to do this, short of keeping track of all the layers
myself and calling setNeedsDisplay on them?
TIA,

Rick
