Viewport smoke: add support to render the volume using a color ramp.
This is yet another debug option that allows to render an arbitrary
simulation field by using a color ramp to inspect its voxel values.
Note that when using this, fire rendering is turned off.
Reviewers: plasmasolutions, gottfried
