Yes that is nice -- the path over eps is a bit strange, cairo should
have native svg export. But not tested yet.

I have recently installed the geda 1.9.1, just to ensure that my own
path processing is compatible. There is indeed some progress, so I
really wonder why it is called instable and not included in
distributions for more than one year.

I wonder about

ldd /usr/bin/gschem

libGL.so.1 => /usr/lib64/libGL.so.1 (0x00007fe689dba000)

What part of gschem may use OpenGl? Maybe cairo-gl backend is used, but
that is generally not advertised by cairo developers? Fast vector
drawing is generally a problem in Linux still -- I am a bit angry about
that. Cairo is fine but not fast, cairo-gl is not really supportet, and
even GTKGLExt seems to have bit rotted, GTK3 is not really official
supported. Seems that fast vector drawing is really better supported in
Qt.

For my gschem peted clone -- I should be able to finish a first working
release soon -- busses, pictures and undo will be unsupported, not
because that is difficult or much work, but because I do not use it.
Maybe I should support svg export for the first release?
