Corrected the handling of toolkit callbacks created by the

"magic::add_dependency" procedure.  The "check" function should always
be called first, followed by the dependencies.  Because otherwise, if
an incorrect value is entered for a device parameter, then it gets
used to calculate dependent values *before* it gets corrected by the
"check" procedure, resulting in an incorrect value being displayed
for the dependent value, even after the bad entry has been corrected.

+	 In the Tcl version of magic, tool types are generated by
+	 procedure and can be modified or overridden.  The four tools
+	 listed above are the default tools known to magic.  If no window
+	 or tool type is given, then the current tool in the current
+	 active layout window is assumed.<P>
+
+	 <I>option</I> may be one of the following:
+	 <DL>
+	    <DT> <B>list</B> [<B>-reverse</B>]
+	    <DD> The key bindings are returned in the form of a Tcl list
+		(Tcl version of magic only).  The returned value is a
+		single list with alternating entries of the macro key and
+		the macro binding.  In Tcl, this list can be treated as a
+		dictionary type of key:value pairs.  With the <B>-reverse</B>
+		option, the keys and values are reversed, resulting in a
+		dictionary that can be searched or listed by function.
+	    <DT> <B>help</B>
+	    <DD> Curently, <B>macro help</B> is equivalent to <B>macro</B>
+		 without arguments, and returns a full list of macro names
+		 and their bindings.
+	    <DT> <B>search</B> <I>text</I>
+	    <DD> Return only results which match (all or in part) the string
+		 <I>text</I>.  For example, <B>macro search grid</B> will
+		 return all key bindings that include the command <B>grid</B>.
+	    <DT> <B>copy</B> <I>tool_name</I>
+	    <DD> This is a method introduced to allow the interactive creation
+		 of new tools, in the Tcl version of magic.  Each tool is defined
+		 specifically by its unique button and key bindings.  Because
+		 tools generally keep most of the same default bindings, the
+		 <B>copy</B> option will copy all the existing bindings to the
+		 new tool from the current tool.  This can be followed by
+		 switching to the new tool and replacing macros with ones
+		 unique to the tool.
