11 wxMirrorDC is a simple wrapper class which is always associated with a real
12 wxDC object and either forwards all of its operations to it without changes
13 (no mirroring takes place) or exchanges @e x and @e y coordinates which
14 makes it possible to reuse the same code to draw a figure and its mirror --
15 i.e. reflection related to the diagonal line x == y.
