Log:
Fix (pdfwrite) : Process text in Tr 3 even if the Widths are non-standard

Bug #691605 "Invisible text not preserved by pdfwrite"

The problem was that if text in text rendering mode 4 (neither stroke nor fill) used a
font where the entries in the FontDescriptor /Widths array did not match the actual 
widths in the font, the code took a path where the glyphs were not added to the 'used'
list, and so were never emitted.

Text in regular fonts where the /Widths array was missing, or matched the widths in the
font (as the spec says they must) worked correctly.

Fixed by processing text whose operation properties include TEXT_RENDER_MORE_3 the
same as text with the TEXT_DO_DRAW property.
