DW> The coordinate system should be described as follows:

DW> width = resulting mm width of VDC extent
DW> height = resulting mm height of VDC extent
Could I please get a pointer to read on how "resulting mm width/height
of VDC extent" gets computed?

DW> Origin:
DW> lower left corner of VDC extent
DW> coordinates at origin: 0,0
DW> top left coordinates: width,height (or 100%,100% where applicable)
What does "or 100%, 100% where applicable" mean, where would it be
applicable?

Thanks,
