* XpGetMaxWidthHeightRes returns into the supplied width and height
* unsigned short pointers the dimensions in millimeters of the largest
* supported media for a specific printer. It looks at the
* medium-source-sizes-supported attribute (if it exists) to determine
* the list of possible media, and calls XpGetMediumMillimeters to get the
* dimensions for each medium. If the m-s-s-s attribute is not defined,
* then the dimensions for the na-letter medium is returned.
*
* This function also returns the largest resolution in DPI defined in
* printer-resolutions-supported. If printer-resolutions-supported is not
* specified, the default is obtained from the passed XpValidatePoolsRec.
*
* The passed XpValidatePoolsRec is also used to determine valid values
* when parsing attribute values.
