added \startTEXpage[pagestate=start] %`pagestate=start` is needed to have incremented page numbering of the pdf
== Finishing Layer ==
The purpose of the finishing layer in the our ConTeXt code is to add the final touches to the drawn layers and to clip the graphic to the same frame. It also includes the addition of page numbering to each page with the help of a Metapost variable, in our case "mypagenumber". We need this method because apparently, it is not possible to use the ConTeXt page numberin numbering on a Metapost page. The finishing layer needs to be applied after drawing all the other layers.
== Layer Sets ==

It's only an intermediate step on the way to the next layersetpage. For that reason, it's not named layersetpage. Because it's coming before the layersetpage4, I call it layersetpre4. If I need another intermediate step stored before layersetpre4, I would call it layersetprepre4. But that's only a naming convention for myself.
