LO 5.4.4.1 on REL 7.2 so GTK2, smath preview nodes with LiberationSerif 1.07.2
matches 2.00.1 and no clipping of text in the Formula Editor frame

Used FontCreator and compared the font metrics for the 1.07.2 and 2.00.1 builds
of LiberationSerif-Regular. They seem identical on the metrics and the general
tab, only difference I saw was 2.00.1 picking up a header field mark: "Apple
specific field 9 -- This field should be set if the font contains any strong
right-to-left glyphs."

I then installed TDF build of LO 5.4.4.1 on REL7.2 [3.10.0-693.11.1.el7.x86_64
#1 SMP Mon Dec 4 23:52:40 UTC 2017 (Centos 7.2)]

Launching smath I see no issue with clipping of text in the sm Formula Editor
frame with GTK2 here. And the formula nodes are well proportioned. 

And if I delete the 5.4.4.1 LiberationSerif*.ttf fronts from
share/fonts/truetype, forcing fall back to the 1.07.2 ver of LiberationSerif
(installed to /usr/share/fonts/liberation for LO 5.0.6.2) the 5.4.4 1 build
does not have problems with the nodes in the preview using the fall back.

So, it doesn't seem to be from fall back font and is something in GTK+ for
Wayland in the Fedora builds.
