+If the wxSTIPPLE variant is used, the bitmap will be used to fill out the

-Note that there is a big difference between stippling in X and Windows.
-On X, the stipple is a mask between the wxBitmap and current colour.
-On Windows, the current colour is ignored, and the bitmap colour is used.
-However, for pre-defined modes like wxCROSS\_HATCH, the behaviour is the
