The way we were loading data into a CoglTexture, then pulling it out and manipulating it on the CPU, then loading it back into a texture was a bit lame. Clean things up a bit here by loading directly into the CPU, doing the fading, then creating a texture. Also cache the faded data in StTextureCache. https://bugzilla.gnome.org/show_bug.cgi?id=612759
