  1. { Frames unit - a set of comprehensive (for my purposes) functions for
  2.     drawing pretty 3-D frames of all types. Pretty simple stuff - I'm sure
  3.     you will be able to figure it out - but that's why I included it.
  4.     As always, you are welcome to do whatever with this unit. I only ask that
  5.     if you upload it somewhere modified, keep my name off it, so I don't have
  6.     to answer for your bad code <grin>. If you have any suggestions or
  7.     questions, by all means send them to me - I'd love to hear from a fellow
  8.     programmer.
