Vista - hardware vector rendering

I know that WPF is touted as being hardware accelerated, but from what
I have seen so far, it is far from it.

It is not at all clear to me how a vector rendering API can be hardware
accelerated using 3D hardware which is specialised on blasting textured
triangles onto the screen.

Can anyone explain to me (i.e. in detail, with links to papers etc) how
a latest-gen DX9 graphics card (e.g. an NVidia 7800) can accelerate the
drawing of, say, a basic WPF-style button (a box with rounded corners,
a gradient of some sort, and a text label).

I know my way around the basics of 3D rendering, but it just doesnt
seem like a credible claim to me.

Looking forward to an explanation.

People are doing all kinds of stuff on shaders - sound and image processing,
H.264 decoding, mathematical calculations. It seems very natural to me that
the cards should be doing curves as well.
