In CVS,

Removed all back layers from glyphs that had them.

In most cases, this layer had been used as a guide, slightly modified to make the front layer. Sometimes it was just a mistake.

However, this is bound to happen again. It would be good to have a script that checks, or maybe a facility in FontForge's "Find Problems".

Note: lots of cases of LayerCount: 2 remain in the .sfd files. I suspect they could be deleted. I wonder if the might have some side effect.

"Back" layers found by editing the .sfd files
Note some other characters have LayerCount set to 2, but no back layer.
Really, this may be a job for a script.

FreeMono has 152 instances. I won't list those.

I don't know any specific example right now, because I have fixed all the ones I found.

In many cases, a ghost copy of a glyph has ben left in the back layer. Sometimes it's completely a different glyph. Apparently, sometimes truetype printers will print both. In any case, for this font, I consider all such back layer glyphs to be bugs.

I need a script or something to help me find them.
