-<h2><center>Alpha Drawing</center></h2>
-
-The wx.GCDC class is a class that implemented the wx.DC API using the
-new wx.GraphicsContext class, and so it supports anti-aliased drawing
-using pens and brushes, that can optionally also be drawn using an
-alpha transparency. (On the Mac all the DC classes are using this new
-implementation.) This is accomplished by enabling the wx.Colour class
-to have a fourth component for the alpha value, where 0 is fully
-transparent, and 255 is fully opaque.
