render: best-effort attempt to set initial window size in chars when scale != 1

Browse source 
The initial window size is set *before* we’re initially mapped. This
means we don’t (yet) know on which output we’ll be mapped. _That_
means we don’t know which scaling factor to use.

This implements a best effort attempt, where we use the “guessed”
scaling factor. This will always be correct in single-monitor
configurations, but may be wrong in multi-monitor setups with
different scaling factors.
