Sets the clipping region for the DC. The clipping region is an area
to which drawing is restricted. Possible uses for the clipping region are for clipping text
or for speeding up window redraws when only a known area of the screen is damaged.
Sets the clipping region for this device context to the intersection of the
given region described by the parameters of this method and the previously set
clipping region. You should call
\helpref{DestroyClippingRegion}{wxdcdestroyclippingregion} if you want to set
the clipping region exactly to the region specified.
