Why is it ok that we no longer invalidate scrollbars after the resize?

[szager1, 2017/05/12 06:15:13]

We don't invalidate the scrollbar because the scrollbar doesn't exist at the
time invalidation runs.  Previously, FrameView would do multiple passes of
creating, then destroying, scrollbars.  This patch eliminates some of the extra
passes, so that by the time invalidation runs, the scrollbars are in their final
state (i.e., they don't exist).

The important thing is that the invalidation rects match up, and they do.
