/*Here is a macro that emulates a wireframe modeler for a single bicubic
patch. This file is only the macro and should be saved as "patcher.mcr"
in order for the next scene file to render. The demo will be of a flat
sixteen point patch. changing the control points in the array will allow
you to model the bicubic patch interactively. This may come in handy for
anyone wanting to do a leaf, a flower petal, or a sheet of paper.  */

  It something Microsoft came up with. Something no-one else understands but
Microsoft only (and perhaps not even them do it).
