Dissolve blending mode. The category should be changed, I don't know about the compositor categories so I just left it at "compositors:math". I tried to follow the way GIMP's dissolve works but gegl is obviously different. There's no mask or opacity input like in GIMP, I assume masking or gegl:opacity is already done on the inputs. Tell me if I need to change something or add those properties.

Moved to GIMP.

New version that subclasses GeglOperationComposer so it could use the buffer class methods.
* the pattern is now fixed (doesn't move when the layer is moved), like the original
* should work with premultiplied and normal colours * looks like the original, except that the pattern is not pixel to pixel identical
* doesn't work when there's no underlying layer (like the other modes at the moment)
There's a problem with the buffer's coordinates. gegl_buffer_get_x or get_y always returns -4096. Is this the correct behaviour?
