Just a thought: maybe sometimes one wants to output unkerned text (for
speed, maybe, or because the font is fixed-size), or wants a better kerning
algorithm. Likewise sometimes one wants antialiased, semi-transparent
painting, sometimes good old aliased opaque is just fine (or even
desireable). So we need an API for specifying that too.
I tried for a while ago to extract a simple API from the PDF model, or from
the Java2D APIs, but if such issues should be taken care of, then there's
not much simplification to be done...
