Device Context: it's the object drawing operations are performed on.
Picture it as an API layer between client drawing code and some
specific device. In GRASS terms, it's like a driver interface.

So you instantiate one kind of DC (MemoryDC, PostScriptDC, MetafileDC,
PrinterDC, and so on) and then use drawing operations irrespective of
the particular back-end.

(It's also my initials :)
