Detailed Description

HIPoint

Discussion: HIPoint is a new, floating point-based type to help express coordinates in a much richer fashion than the classic QuickDraw points. It will, in time, be more heavily used throughout the Toolbox. For now, it is replacing our use of typeQDPoint in mouse events. This is to better support sub-pixel tablet coordinates. If you ask for a mouse location with typeQDPoint, and the point is actually stored as typeHIPoint, it will automatically be coerced to typeQDPoint for you, so this change should be largely transparent to applications. HIPoints are in screen space, i.e. the top left of the screen is 0, 0.
