/****************************************************************************
NAME
XCreateInsensitivePixmap - create a grayed-out copy of a pixmap
SYNOPSIS
Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
DESCRIPTION
This function creates a grayed-out copy of the argument pixmap, suitable
for use as a XmLabel's XmNlabelInsensitivePixmap resource.
RETURN VALUES
The return value is the new Pixmap id or zero on error. Errors include
a NULL display argument or an invalid Pixmap argument.
ERRORS
If one of the XLib functions fail, it will produce a X error. The
default X error handler prints a diagnostic and calls exit().
