Not quite replying to right part of the thread, but I thought it should be
mentioned that (AFAIR) translucency in PDF >=1.4 is limited to vector fills.

Even if we use the much faster PNG(PPM) driver for fast GUI rendering, it sure
would be nice to click a "quality mode" switch in the GUI to switch to the
Cairo driver to create presentation quality output. For hardcopies (or softcopy
raster output for presentation or web publication) quality is much more
important than speed. (up the point it takes all night to render) For the GUI
speed becomes the important factor, quality is reduced to a nice bonus.
