Based on #3713 a number of problems were solved, but also some new issues introduced.
- BaseDoxyfile.h see to it that the CGALAdvancedBegin is in a detailed part, so be sure to terminate the brief part by an extra carriage return
- commands like \pre, \note read till the beginning of the next section but a \htmlonly is not seen as a section separator, so insert an extra carriage return
- some places missed an "Advanced" indicator, used the cgalAdvancedType here.
##Note
in Periodic_2_triangulation_2.h there appear to be a number of images that are a bit in thin air (Captions: "Insertion of a point on an edge." and "Insertion in a face."). Also just above these images theer are a number of functions that have documentation, but this is non-doxygen documentation and as such not seen by doxygen
Form the doxygen documentation:
Normally the contents between \htmlonly and \endhtmlonly is inserted as-is. When you want to insert a HTML
fragment that has block scope like a table or list which should appear outside <p>..</p>, this can lead to invalid
HTML. You can use \htmlonly[block] to make doxygen end the current paragraph and restart it after \endhtmlonly.
