Title: GPUImagePicture: don't redraw using CoreGraphics unless you have to

There was support for this but it appeared to have been disabled. I've tested this in my project and it seems to still work as expected, and significantly reduces memory usage by not needing to redraw these graphics. I think was just a typo.
