	AX = 006Ah
	ES:BX -> ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. filename for PCX image
	CX = control flags
	    bit 0: use current palette, overriding stored .PCX palette
	    bit 1: load at current graphics position, not stored position
	    bit 2: load image from FG_IMAGEBUF buffer instead of .PCX file
Return: AX = status
	    0000h successful
	    0001h file not found
	    0002h not a .PCX file
Note:	the FGDRIVER functions are rearranged with each major release, but
