Subject: Make scrolling-by-selection smoother
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=73bfef16f3d5a9fe1064dfb8b2782bf82111e4c0;p=lyx.git

Make scrolling-by-selection smoother

This trivial patch makes scrolling-by-selection smoother by dividing
the step size and the time between steps by 8 when generating
synthetic events in work area.

The scrolling speed is unchanged, but the result is visually better.

(cherry picked from commit 1cc1f0ba27d1846ba244507529d4795ecfa29a39)
