[Thuban-list] HSV ramps (patch)

[Daniel Calvelo Aros]

Hi all.

The attached patch provides HSV color ramps. That is, the interpolation for
color ramps is made in HSV, not RGB colorspace. I patched the CustomRamp
dialog to let the user choose either. For instance, an HSV ramp from red to
green would go through yellow. Could be useful to some.

Daniel.

PS. I'm still in the classification stuff. Sending patches real soon now.
