  Aspen Theme - Copyright 2011, Bruce E Wampler

	Dynamically generate CSS for tinyMCE. This is called from the tinyMCE script.
	When this file is invoked, there is no context at all. There is no access to any
	WordPress functions - nothing.
	Since there really are not very many options needed to get the editor to match
	a post or content area, parameters are passed via $_GET.
	Note that all this is desireable to avoid having to create an actual override
	file since the WordPress theme requirements don't allow the use of fopen or fwrite.
	This turns out to be much easier, anyway.
