## Message

```
Consolidate calculation of editor's visible row range

We think this will fix a panic that was occuring in `paint_highlighted_range`
due to an out-of-bounds read into the line layouts. We think doing essentially the same
calculation in two different ways with floating point numbers might have
caused a different end row to be calculated in 2 different code paths.
