QML UI: scale profile in two stages

Browse source 
Scale the QML profile in two stages.  Firstly, scale to fit.  Secondly, scale
again to 95% to create a margin around the profile.

The previous method scales to fit a create a margin in one step.  It appears
more elegant, and the margin is calculated more rationally.  Unfortunately on
some devices, including mine, the resulting profile is cropped for no obvious
reason.
