Add a way to add a title to the images

[DeflateAwning]

Either a titleblock or a top-of-page title would be good.

If this does exist, it should be added to more examples.

Power supplies.pdf

You can use the template function for that? The title block only shows up in the .html file, but you could export that to a pdf and have the titleblock integrated.

Awesome, thanks! My request remains that adding a title to PNG exports would be very helpful!

This issue seems a bit similar to #227 and #428.
