View source for Surface ramp above mode

The '''surface_ramp_above_mode''' setting is for coloring [[surface|molecular surfaces]] by electrostatic potential, using a [[ramp_new|color ramp]]. If '''on''', the surface is colored by the potential on the [[surface_solvent|solvent accessible surface]], which is one solvent radius above the surface.

Coloring with ''surface_solvent=0'' and ''surface_ramp_above_mode=0'' is less meaningful, since a solvent or ligand atom never reaches the molecular surface of the protein (only the accessible surface). Furthermore, ''surface_solvent=1'' with ''surface_ramp_above_mode=1'' isn't meaningful either.
