width and height value in <advance> tag

[hatchzo]

If a ufo file has both height and width values in tag, AFDKO tools drop the width value from the font. Please check C12139, C12140, C12141 and C12142 in the attachment, and then tx -t1 JPSymbol-EL.ufo > JPSymbol-EL.pfa. The problem produces on mergefonts too.

The problem is deeper than a bug. The reason that tx and mergefonts drop the vertical advance width when they write to *.pfa and *.cff is the the output font format has nowhere to store vertical advances. This is stored only in the OTF vmtx table. A separate process will be needed to fill out a feature file specification of the vmtx table from the vertical advance widths in a UFO.

@rroberts The issue is that the horizontal advance, which is specified as the second element of <advance height="1000" width="1000"/>, is being ignored, resulting in a glyph with a zero-width horizontal advance.
