GCDC is a Device Context that supports anti-aliased drawing
and semi-transparent colours on all platforms. It is somewhat slower
than normal device contexts, so it is not enabled by default (except on
OS X). It is used by taking a normal WindowDC and creating a GCDC from it.
GraphicsContext and associated classes provides a
more advanced interface to the native anti-aliased drawing features.
