Simulation support:
This function is simulated by a handling routine in the graphics engine.
Description
GreBoxBoth draws and fills a rectangular box with one corner at the current (X,Y) position and the opposite corner at the specified (X,Y) position. The current (X,Y) position does not change. When this function occurs within an area or path definition, it generates a closed figure. GreBoxBoth must not occur within any other figure definition.
This function is supported by the graphics engine and can be hooked by the presentation driver.
