  62 /*  FUNCTION
  63         Initializes a RastPort structure.
  64
  65     INPUTS
  66         rp - The RastPort to initialize.
  67
  68     RESULT
  69         TRUE if the RastPort was successfuly initialized and FALSE
  70         otherwise.
  71
  72     NOTES
  73         You must call DeinitRastPort() before you free the structure.
  74
  75         AROS defines this function with a return value which you should
  76         check.
