I want to animate the drawing of CGPath in a UIView, so it looks as if it's
being drawn. I have the UIView, I have the CGPath, I am able to split the
CGPath at any point from 0 to 100% into that which should be drawn and that
which shouldn't yet, that's all done, so I can, fairly efficiently,
hmm .. actually it looks like I can TOTALLY use CALayer for this. I need a
better book, the one I have doesn't cover this. Hitting google.

There are several paths to be animated. I want each to appear when the user
does some action. It seemed the best to but them in a method called by drawRect
and redraw the view when something changed. Why would the memory footprint be
enlarged?
thanks for pointing to didMoveToWindow.
