Note: Where this data type represents a graphic coordinate in world or model space, its value is restricted to -134 217 728 through 134 217 727.
A graphic coordinate in device or screen coordinates is restricted to -32 768 through 32 767.
The value of a graphic coordinate may be further restricted by any transforms currently in force, including the positioning of the origin of the window on the screen. In particular, coordinates in world or model space must not generate coordinate values after transformation (that is, in device or screen space) outside the range -32 768 through 32 767.
