Only set the major curve's range once (per render cycle) 

Turns out this is a limitation of the `ViewBox.setYRange()` api: you
can't call it more then once and expect anything but the first call to
be applied without letting a render cycle run. As such, we wait until
the end of the log-linear scaling loop to finally apply the major curves
y-mx/mn after all minor curves have been evaluated.

This also drops all the debug prints (for now) to get a feel for latency
in production mode.
