Half float textures would

Half float textures would only be supported as initial inputs to the filter, not as outputs from any stage. You can only input half float textures on the iPhone 4S, iPad 2, and iPad 3, and even there you can't use them as rendering targets, so I doubt they'd be of much use to you in this framework.

You could supply one as an input to a GPUImageTextureInput right now, without any modification to the framework. Again, since you can't use it as an output, its utility would be limited.

Also, apparently they are incredibly slow on the 4S: http://stackoverflow.com/a/9718795/19679
