Example code in the RISC OS branch. sqRPCWindows.c|ioShowDisplayOnWindow() 
When a display operation is intended to affect the on-screen display, if no window already exists, make one first, then do the normal display work.  If no displaying is ever done - oh, I don't know, maybe because the image is set up to be a headless server - then no window needs to be created.
