/**
@class wxPaintDC
A wxPaintDC must be constructed if an application wishes to paint on the
client area of a window from within an EVT_PAINT() event handler. This
should normally be constructed as a temporary stack object; don't store a
wxPaintDC object. If you have an EVT_PAINT() handler, you @e must create a
wxPaintDC object within it even if you don't actually use it.
Using wxPaintDC within your EVT_PAINT() handler is important because it
automatically sets the clipping area to the damaged area of the window.
Attempts to draw outside this area do not appear.
To draw on a window from outside your EVT_PAINT() handler, construct a
wxClientDC object.
To draw on the whole window including decorations, construct a wxWindowDC
object (Windows only).
A wxPaintDC object is initialized to use the same font and colours as the
window it is associated with.
