<B>Tk_Visual</B>, <B>Tk_Depth</B>, and <B>Tk_Colormap</B> return
information about the visual characteristics of a window.
<B>Tk_Visual</B> returns the visual type for
the window, <B>Tk_Depth</B> returns the number of bits per pixel,
and <B>Tk_Colormap</B> returns the current
colormap for the window.  The visual characteristics are
normally set from the defaults for the window's screen, but
they may be overridden by calling <B><A HREF="SetVisual.html">Tk_SetWindowVisual</A></B>.
