[NTG-context] TEXpage filename

Hello, In the production of (scientific) articles for journal submissions, one is often expected to supply the figures as separate files. One workflow can be through the use of \startTEXpage\stopTEXpage followed by an external extraction of single pdf pages to separate files.
