Int 62 Fn 008D  u - Fgdriver V4.02 - "fg_pcxrange" - Get Extent Of Pcx Im  [V]

   AX = 008Dh
   ES:BX -> variable pointer record (see #3166)

Return: indicated variables updated; if the indicated header is not valid,
     all of the coordinate variables are set to FFFFh

Note:  the FGDRIVER functions are rearranged with each major release, but
     their parameters do not change (see #3145 at AX=0000h)
