Derived types of wxDC have documentation for specific features
only, so refer to this section for most device context information.
+% VZ: we should really document them instead of this lame excuse, but I don't
+% have time for it now, when it is done please remove this
+Please note that in addition to the versions of the methods documented here,
+there are also versions which accept single {\tt wxPoint} parameter instead of
+two {\tt wxCoord} ones or {\tt wxPoint} and {\tt wxSize} instead of four of
+them.

\membersection{wxDC::Clear}\label{wxdcclear}
\func{void}{Clear}{\void}
Draw a bitmap on the device context at the specified point. If {\it transparent} is TRUE and the bitmap has
a transparency mask, the bitmap will be drawn transparently.
+When drawing a mono-bitmap, the current text foreground colour will be used to draw the foreground
+of the bitmap (all bits set to 1), and the current text background colour to draw the background
+(all bits set to 0). See also \helpref{SetTextForeground}{wxdcsettextforeground},

Draws an arc of an ellipse. The current pen is used for drawing the arc and

-X window and PostScript device contexts.

{\it x} and {\it y} specify the x and y coordinates of the upper-left corner of the rectangle that contains
the ellipse.
