David G. Yu b0d612f837 Restored support for fractional tessellation 
This change includes support for both fractional_even_spacing
and fractional_odd_spacing.

The implementation follows the existing pattern of re-parameterizing
the tessellation domain only along transition boundary edges. This
allows for crack-free tessellation, but it might be better to
consistently re-parameterize all of the outer edges of all patches,
which also would be required for numerically watertight tessellation.

This is implemented in a way that requires no changes to the client
shader API. It should be more efficient to move some computations to
the control/hull shaders and reduce divergence in the execution of
eval/domain shaders.
