Simulation support:

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

Description:

GreSetGraphicsField sets the boundaries of the graphics field (clip) limits in page-coordinate space. The boundaries are inclusive so that points on them are not clipped. By default, no clipping is performed.

This function can be hooked by the presentation driver.
