 Selects the given bitmap into the device context, to use as the memory
 bitmap. Selecting the bitmap into a memory DC allows you to draw into
 the DC (and therefore the bitmap) and also to use {\bf Blit} to copy
-the bitmap to a canvas. For this purpose, you may find \helpref{wxDC::DrawIcon}{wxdcdrawicon}\rtfsp
