[MonoTouch] CGImageCreate?

[Miguel de Icaza]

Hello Ed,

      Please download:

	http://tirania.org/tmp/monotouch.dll

     After backing up your /Developer/MonoTouch/usr/lib/mono/2.1/ 
monotouch.dll, override it with this file.

     You can now use CGDataProvider like this:

	using (var image = new CGDataProvider (your_memory_block,  
size_of_block)){
		var image = new CGImage (...., provider, ...);
	}

      Let me know if there are any problems with it.
