+A palette is a table that maps pixel values to RGB colours. It allows the
+colours of a low-depth bitmap, for example, to be mapped to the available
+colours in a display. The notion of palettes is becoming more and more
+obsolete nowadays and only the MSW port is still using a native palette.
+All other ports use generic code which is basically just an array of
+colours. 
+
+It is likely that in the future the only use for palettes within wxWidgets
+will be for representing colour indeces from images (such as GIF or PNG).
+The image handlers for these formats have been modified to create a palette
+if there is such information in the original image file (usually 256 or less
+colour images). See \helpref{wxImage}{wximage} for more information.
