There are three conversion functions defined in ieps.cxx [1], they depend on
the helper programs being installed and on PATH, so no surprise differing
results.

RenderAsEMF -- requires pstoedit & ghostscript
RenderAsBMPThroughConvert -- requires Imagemagick & ghostscript
RenderAsBMPThroughGS -- requires ghostscript


On master/7.1.0, inserting the image onto Writer canvas, I get the same
squished result on Windows where I have Imagemagick IM (convert.exe) ahead of
ghostscript (gswin64c.exe) on PATH. But I get similar results using either BMP
conversion, when I suppress convert.

I don't currently have the pstoedit helper loaded--as its vector output of a
parsed EPS is poor.

But IM identify.exe shows the image as 8.5x11 and 612 x 792px at 72dpi, so
clearly the resulting filter imported BMP is not scaled correctly in the
y-dimension.

We have bug 67464 open to implement our own EPS parser--but it is not likely to
advance.
