Since I am new, I have posted my proposed mods as an attachment to PDFBOX-1628 rather than commit them via SVN. The job is not done. A glyph image now gets placed on the image, but it is too large, upside-down, and in the wrong place. Clearly the affine transform needs to be adjusted. But this is not one of my skills -- and I have run out of time -- so I leave completion to you.
