// Creates a bitmap that matches the device context's depth, from an
// arbitray bitmap. At present, the original bitmap must have an associated
// palette. (TODO: use a default palette if no palette exists.) This
// function is necessary for you to Blit an arbitrary bitmap (which may
// have the wrong depth). wxDC::SelectObject will compare the depth of the
// bitmap with the DC's depth, and create a new bitmap if the depths
// differ. Eventually we should perhaps make this a public API function so
// that an app can efficiently produce bitmaps of the correct depth. The
// Windows solution is to use SetDibBits to blit an arbotrary DIB directly
// to a DC, but this is too Windows-specific, hence this solution of
// quietly converting the wxBitmap. Contributed by Frederic Villeneuve
