Subject: Fix bad refresh when changing zoom level
X-Git-Tag: 2.3.1~133^2~88^2~11
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=f6cbc08a7db3c2185b6eae768c026c58f577b0bc;p=features.git

Fix bad refresh when changing zoom level

Replace the tricky code in LFUN_SCREEN_FONT_UPDATE and replace it with
proper use of DispatchResult flags.

LFUN_BUFFER_ZOOM* does not need to call LFUN_SCREEN_FONT_UPDATE, since
it already does everything that is required.

(cherry picked from commit 9df59aac63bbb56d9d5f5ddcccfaa3ebace2f03d)
