[Neil Baylis]

Attached are two demos to be included in the contribs.

ca-demo.lisp is a replacement for my original ca-demo that loads an image
into a layer and lets you drag it around inside a window, using the GPU to
animate the dragging. This demo has been reworked so that it functions on
both 10.5 and 10.6, and tested under CCL1.5 on intel and ppc 32 bit. It no
longer requires a 64 bit ccl in order to function.

ca-multilayer.lisp allows you to test your system's performance when
animating a large number of layers simultaneously. You can run top while
dragging the mouse within the window to see the results.

Thanks to Raffael Cavallaro and Arthur Cater for their help in sorting out
various incompatibility issues that caused problems with 10.6 initially.
