Aggressively cache line height for computing margin sizes
Computing the line height is a very costly operation that involves font
loading and measuring, but the value stays mostly the same over time,
as it depends on font, zoom and a couple other style settings which
rarely change.
As line height used to compute margin widths dominates startup timings,
we now cache the latest result. This caching makes line height
computation barely noticeable in startup times now.
Fixes #2649.
