Simulation support:

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

Description

GreAreaSetAttributes is called by the graphics engine after processing a call to GreSetAttrs received inside an area or path bracket. The handling routine in the graphics engine does nothing. Its purpose is to provide an entry in the dispatch table that can be hooked by presentation drivers.

This function must be hooked by presentation drivers that perform their own area or path simulations.
