I've made big progress! I googled for the invalid-pixel-format-attributes error
on a whim and I ended up on some Java forum. Apparently the core-profile flags
clash with the windowed flag. Removing that I can create now a window where
[ gl-version . ] into-window
reports 3.2 and all the other usual GL functions work as well. I am very happy
about this!
