Subject: Use a tighter threshold when checking for duplicate modes
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgui.git;a=commitdiff_plain;h=8811d614b5deb1a0da4bef531db3fd6882469b99

Use a tighter threshold when checking for duplicate modes

Some display devices offer modes with refresh rates very close to each
other, such as 24.00 and 23.97.  These differences may nevertheless be
important for video content.
