Constant description
kATSUUseGrafPortPenLoc
Indicates that drawing, measuring, or hit-testing should be done relative to the current pen location in the current graphics port. ATSUI looks at the current graphics port location (it knows the last draw location from moves and lineto calls) and uses that.
