Simulation support:

This function is simulated by a handling routine in the graphics engine.

Description

GreFullArcBoundary draws a line by using the current line attributes around the edge of a full arc centered on the current (X,Y) position. The dimensions of the arc are defined as a multiplier that is applied to the current arc parameters. GreFullArcxxx functions do not affect the current position.

When correlating, the handling routine must return a hit when the pick aperture intersects the boundary. See Mix Modes.

This function can be hooked by the presentation driver.
