Image maps for HTML reports (new feature)

Previously, GIF pictures in HTML generated from MetaEdit+ were not
clickable maps. This patch, imagemap.pat, adds a client-side map
automatically to an HTML file whenever a gif file is generated. It 
also redefines the _Dictionary in HTML report in Graph: if you have
changed that, be sure to take a copy before applying this patch.

When a filename;...;print; command is executed in the report, if
the stream that is open after the print; command is a file named *.htm*,
an image map will be written to that stream at the current position.
That position should thus not be inside any other tag; other than that,
it may be anywhere in the body of the HTML file. 

The image map includes a polygon entry for each object, based on the
connection points of that object. The href parameter for each entry is
generated by an automatically run subreports, _imagemap_href. The
default for this is in Graph, and makes the link point to a local target
named with the oid of the object, e.g. #16_2876. It also uses
onMouseOver and onMouseOut to display the name and type of that object
in the browser status bar. If the name or type contains an apostrophe,
Netscape 4.5 gives a JavaScript error: 4.6 and Internet Explorer 4.0
do not have this problem.

You may override the default _imagemap_href report in your own Graph
types by making reports there with the same name. Add the
USEMAP="#filename.gif" parameter to the IMG tag: the filename.gif should
be exactly the same as the SRC parameter, preceded by #. 

MetaEdit+'s standard repository includes the Project Model graph type,
which has a report that should be changed to use an image map. Also, a
custom _imagemap_href report can be added to Project Model, to make the
links point to the HTML pages for the individual Graph and Subproject
objects' graphs. See the report files in the directory
ftp://www.forms.fi/metacase/reports/30/

You can read these reports in from a Report Browser opened on Project Model.
