PDFGraphics2D patched w.r.t. fop-0.91

I hope that the patch file is what you want, I'm not familiar with the
subversion system, I generated it using TortoiseSVN.

Few comments, as things changed quite a bit since my last post:

1) the code for generating string output mysteriously changed since last time,
the translation of text was moved from graphic's global transform to text's
local transform, so it was more difficult to combine with font's transform, but
I did it anyway, so hopefully it works. I tested it on two typical cases:
narrowed text and slanted text. Please note that I did not change drawString
with AttributedCharacterIterator as I do not use it, but the change is
analogous. Suprisingly this second method uses the "old" way of combining
graphic and text transforms, i.e. the text translation is combined with graphic
transform, and the text uses simple Y inverse transform

2) the transparency handling changed a lot, but the bug is still there. It
seems to me that it is sufficient to comment out forgotten
BitmapImage.setTransparent line. The transparency seems to be correctly handled
by a companion mask stream added to the primary bitmap stream.
