Our PDF graphics interpreter only handles basic primitives.
TikZ/PGF (and hence beamer) often uses shading. The difficulty with this is that is it not done using new instructions (that we could implement), but by defining and referencing resources external to the instruction stream.
Our interpreter lacks both features: no notion of resources, no way to define nor reference them.
