Some edge filters in GEGL

Hello everyone. As a way to learn how GEGL works, I decided to implement some GIMP plug-ins in it [1,2]. I hope this code can help someone in the task of making your own plugins. I've done a sobel and a laplace filter. Both use RGBA float format for input and output. Basically, I just do a convolution with the appropriate mask, although in sobel filter I implemented some of the options of the original GIMP plugin.

There are some differences in the results, but I think this code is "almost there" to whom wants to port these plugins to GEGL.

Thanks! I haven't done a thorough review, but it looks like a good start. Can you create a patch with git format-patch and attach it to bugzilla please?
