Draw a fence panel connecting two wells, joining up
common zones, and texture map image data onto
the fence panels.
This routine takes three geometric field inputs, one the
zonation table, containing a 2D array of wells and zones,
and the deviation scatter path data for two wells.
It creates a geometric representation of the zonation region
between the wells. The depths are resampled using linear
interpolation from the deviation data to create a 3D sheet.
Two optional inputs, texture image A and B, if present
will texture map onto alternate panels of the fence.
It looks at the labels on the well dev field to figure
out which well it is, then indexes the zonations by this,
so there is no menu selection needed here.
