thanks for the patch it was cut 'n paste error bah :(
Not sure why string opacity shouldn't work; we're just setting an extended
graphics state so it should apply to all fills/strokes etc etc. Of course text
does have a separate kind of existence in PDF.
I have changed the original test in test_platypus_general.py to output some
strings using canvas.drawString and the opacity stuff seems to work there at
least in the acrobat viewer (see attached).
I suppose the String objects must be doing something special. The renderPDF
drawString seems to use canvas beginText ...endText to draw the string, but that
seems to be what canvas drawString does.
