Optimize graph rendering #21

Are you accepting pull requests?

I have a database which has accumulated a few thousand entries over the years. The plot page has become unbearably slow. This change makes it usable again by moving rendering to the native code.

Checked with valgrind - nodes don't leak (that part may be a bit confusing).

Hmm, the QString => qreal change slightly breaks the raw data view...

Dropped the commit which was causing the breakage.

Looks like pull requests are not accepted and I have to maintain my own fork. So be it.

Thank you very much for the original version! It served me well for years.
