[poppler] Ghostscript fails to render some glyph at very small size.

[Thomas Freitag]

FYI:

Generating ps output with pdftops could cause the actual gs version 9.05 
to show only a black square, if the PDF contains a font which is scaled 
very small, i.e.
/F1_0 0.02 Tf
This is NOT a poppler problem and will be fixed in gs 9.06. s.
