 /* Wolfram Gloger <u7y22ab@sunmail.lrz-muenchen.de>
 I have implemented basic colormap support for the X11 versions of
-wxWindows, notably wxPalette::Create().  The way I did it is to
+wxWidgets, notably wxPalette::Create().  The way I did it is to
 allocate additional read-only color cells in the default colormap.  In
 general you will get arbitrary pixel values assigned to these new
-cells and therefore I added a method wxColourMap::TransferBitmap()

 which maps the pixel values 0..n to the real ones obtained with
 Create().  This is only implemented for the popular case of 8-bit
 depth.
