  32 /*  FUNCTION
  33         Move the layer to a specified position in the bitmap.
  34         Parts of simple layers that become visible are added to
  35         the damage list and a refresh is triggered.
  36
  37     INPUTS
  38         dummy - unused
  39         l     - pointer to layer to be moved
  40         dx    - delta to add to current x position
  41         dy    - delta to add to current y position
  42
  43     RESULT
  44         result - TRUE everyting went alright
  45                  FALSE an error occurred (out of memory)
