Units used in bold, thin and hollow transformations

@Erwin Denissen

It was a design decision to not allow undo there. It requires a lot of development efforts to implement it. I can add your request to our to-do list, but I believe there are more important things on it.

Hm? Undo is already there, no? Would it really be more complicated than:

if len(selected_glyphs) > 10:
    msgbox(opt.warning, "Operations on more than 10 glyphs cannot be undone.")
    undobuffer.empty()

Well I leave it to you.

@Bhikkhu Pesala

To work around the undo problem, copy the selected glyphs to the clipboard, then perform the transformation. Paste the glyphs back immediately, then undo the paste operation. Now, if you want to try with different transformation parameters, you can undo and try again.

Yes bhante, you had mentioned this in your tutorial on glyph transformer. I just would like to avoid the trouble. Anyhow…
