PCVideo and graphics support

PCVideo continues to provide all the screen-driving support, either graphic or based on graphics, that Ports requires. To do so in Turbo Pascal, it relies on Borland's unit Graph and the .BGI ( Borland Graphic Interface) files that Graph uses. PCVideo presumes that the .BGI file it needs is in the current directory. The current version does not attempt to search any other directory.

It is therefore important when packaging Turbo Pascal dialogues to make sure all .BGI files for graphics adapters that PCVideo should be able to support are placed in what will be the current directory at runtime.
