Extending gggl

gggl aims to have an as simple op plug-in interface as possible, and strives to make it easy to implement new ops.

Browse the sources of other ops to see how they achieve things.

If you develop an Op from scratch, please implement a floating point version first,. and then implement accelerated 8bit or 16bit versions, doing it in this order will ensure ability to pass high dynamic range images through gggl.
