Overlays are a framed feature (the page background is a frame too) and textbackgrounds are images which are drawn on the page like overlays.
MetaPost graphics can be hooked into the textbackground using the mp and method keys. So apparently there is a way to use arbitrary background graphics. It would be a natural consistent interface if overlays worked with the background key. But I assume it's due to the page break ability of textbackground that makes it more complicated to implement. BTW: Is there any documentation, except the source, about the mp and method keys? Marco
