Description Matthieu Herrb 2007-06-13 15:38:33 UTC 
xterm version 225 (and probably other applications) use XftDrawSetClipRectangles() by default to limit the areas in which text is drawn. 
When running xterm-255 on a big endian machine, with a DISPLAY on a little endian machine, no text is displayed. 

The attached test program demonstrates the problem. Just run it on mixed endianess client/server combinaison. 

A detailled analysis of the problem shows that SProcRenderSetPictureClipRectangles fails to swap the xOrigin and yOrigin members of the X request.
