Simulation support:

None. This function is mandatory for all drivers.

Description:

GrePolyShortLine draws a series of shortlines. The current (X,Y) position is not changed. A polyshortline is a linked list of shortlines.

This function must be supported by all presentation drivers except those that hook GrePolyLine and all of the GreArcxxx functions that are simulated by handling routines in the graphics engine. All function calls to GrePolyShortLine come from either GrePolyLine or the GreArcxxx functions. GrePolyShortLine might be accessed from any of the curve-rendering functions. However, it is not guaranteed that curve rendering will call GrePolyShortLine.
