profile: move axis animation code to ProfileView

Browse source 
This feels quite a bit slower than the non-QtQuick version. This
makes sense, as there is an additional level of indirection. Instead
of painting directly, we paint into an QImage and turn that into
a QSGTexture.

Ultimately one would think that we should render directly using
QtQuick. Alas, we can't, since that would mean no more printing/
exporting of profiles. How sad.
