profile: start with "absolutizing" the profile layout

Browse source 
The chart items were laid out in relative terms with respect
to a fixed scene size (100.0, 100.0). This simply does not
cut it when resizing the chart. Why should the axes always
occupy the same fraction of the chart independent of the size.

Moreover, this led to basically unmaintainable code.

Resize the scene according to the viewport and do
absolute placement of the items. This breaks the layout,
but at least now we have a chance to fix things
somewhat reasonably.
