DPSOperators declares functions that are used for drawing text and graphics and low-level window and event operations. For the most part the window and event functions are not meant to be used in a normal application, it is better to use the methods in the GNUstep GUI library that coorespond to these functions.

All DPSOperator functions take as their first argument a context opject of type NSGraphicsContext. To get the current context, one can use the function GSCurrentContext().
