** 1 - The color palette is a number from 0 to 1120.  The first 32 numbers
**     are normal RGB colors, but the rest index into a pre-defined
**     set of patterns.
**
** 2 - The view depth of each polygon determines the display order.  The
**     higher the number the closer the polygon is to the viewer.  During
**     editing, each polygon is assigned numbers in multiplies of 100,
**     but to function, any number can work.
