Hi Soeren,

I've looked at the patches (bugs #5466, 5467, 5477) that fix the 
tessellation of the vtkBiQuadraticXXX cells already in VTK and have 
permission from Berk to apply the fixes; I'll check them in soon.

As for new cell types, I haven't seen any patches in the VTK bug tracker 
that add new types. Are there any issues beyond the 3 above? (Note: as I 
understand things, Kitware doesn't want to add new cell types right now, 
so I'm not volunteering to commit those patches if there are any. I 
would like to look at them, though.)
