"A wx.DC is a device context onto which graphics and text can be
drawn. It is intended to represent a number of output devices in a
generic way, so a window can have a device context associated with it,
and a printer also has a device context. In this way, the same piece
of code may write to a number of different devices, if the device
context is used as a parameter.

Derived types of wxDC have documentation for specific features only,
so refer to this section for most device context information.

The wx.DC class is abstract and can not be instantiated, you must use
one of the derived classes instead.  Which one will depend on the
situation in which it is used.", "");

Note that in X, text drawing isn't handled consistently with the
mapping mode; a font is always specified in point size. However,
setting the user scale (see `SetUserScale`) scales the text
appropriately. In Windows, scalable TrueType fonts are always used; in
X, results depend on availability of fonts, but usually a reasonable
match is found.

The coordinate origin is always at the top left of the screen/printer.

Drawing to a Windows printer device context uses the current mapping
mode, but mapping mode is currently ignored for PostScript output.

reuse it the next time something needs painted, or you can let the
buffered DC create and provide a buffer bitmap itself.

Buffered DCs can be used in the same way as any other device context.
wx.BufferedDC itself typically replaces `wx.ClientDC`, if you want to
use it in your EVT_PAINT handler, you should look at
`wx.BufferedPaintDC`.  You can also use a wx.BufferedDC without
providing a target DC.  In this case the operations done on the dc
will only be written to the buffer bitmap and *not* to any window, so
you will want to have provided the buffer bitmap and then reuse it
when it needs painted to the window.

Please note that GTK+ 2.0 and OS X provide double buffering themselves
natively.  You may want to use `wx.Window.IsDoubleBuffered` to
determine whether you need to use buffering or not, or use
`wx.AutoBufferedPaintDC` to avoid needless double buffering on systems

        it is the size of the bitmap that will be created internally
