Description

As per the summary, the streaky, wrong-looking coloring by map value is because surface cap triangles are not subdivided into more localized bits instead of long shards. Example image attached.

Fixed.

I made clip caps by default use subdivision 1.0, the same as what Chimera uses.

I added a "surface cap" command option called subdivision to set the subdivision value, for example, "surface cap subdiv 2". A value of 0 means no subdivision giving the long skinny triangles that each span from edge to edge of the cap.

I added a preference setting "Cap subdivision factor" under the Clipping tab. Also I renamed "Surface caps" (boolean) to "Cap clipped surfaces" (sadly to get the options in a decent order, since they are alphabetically ordered).
