%  RenderX11() renders text on the image with an X11 font.  It also returns the

%    o image: the image.
%
%    o draw_info: the draw info.
%
%    o offset: (x,y) location of text relative to image.
%
%    o metrics: bounding box of text.
%
%    o exception: return any errors or warnings in this structure.
