The TODO list is in the comments of backend_pdf.py:

# * the alpha channel of images
# * image compression could be improved (PDF supports png-like compression) 
# * encoding of fonts, including mathtext fonts and unicode support
# * Type 1 and Base-14 font support (i.e., "pdf.use_afm") 
# * TTF support has lots of small TODOs, e.g. how do you know if a font  
#   is serif/sans-serif, or symbolic/non-symbolic? 
# * draw_markers, draw_line_collection, etc. 
# * use_tex 

I think the most important thing to fix is the font support. TTF
embedding mostly works but I haven't figured out the encoding issues,
and it would be really nice to be able to do font subsetting. I was
going to look into the Fonttools library by Just van Rossum, but
lately I've been too busy with other things to.

Great! Is there a patch somewhere?
