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.multichartz_backup
