Pattern Editor: Moving the left vertical notes does not move the grid

[wundermusiker]

Ubuntu 19.10 from KX Repo

When I use the pattern Editor and move the grid, the notes move as well. When I accidently move the notes verticaly, then the grid stays in place.

Just compiled myself the GTK Version. No issues. Only the QT Version affected

I finally duplicated/understood the issue and am looking into it. Right now the qscrollmaster feeds the scrollbar changes to seqkeys/qseqkey, but there is no feeding the keys scroll position back to the scrollmaster. While I am researching, there is a workaround.... move the vertical scrollbar at the right, and the keys will scroll to the correct position. I will assiduously research this issue until I reach a dead end.

I've also fixed an issue in configure for Debian Sid, which uses gcc/g++/cpp version 9 by default, but which has a nasty bug where cpp can't find limits.h. It never ends with GNU software! Love it though we do. :-)

The fix is a workaround. Ideally, moving the piano keys (qseqkeys) up and down would pass the events to the qscrollmaster so that it could also move the piano roll (qseqroll) up and down. But currently, qseqkeys doesn't have access to the qscrollmaster. Not sure that it's worth it. However, at some point we would like to use the scroll wheel more generally.
