Stage3d: UV Mapping a Trapezoid?

Hey all, I need some help!

I want to UV map a Trapezoidal Quad but the way the pixels are interpolated makes it look crazy. Here is exactly what is happening:

http://www.xyzw.us/~cass/qcoord/

That link even proposes a solution, using a four dimensional texture mapping to fix the interpolating. My question is, does Stage3d support four dimensional texture coordinates? I've done a ton of digging to find any documentation on this but have come up empty.

Anyone know how to UV map a trapezoid in Stage3d? Thanks
