2f8ba5b7e7 Fix cpuEvalLimitController crash bug
Properly check that derivative data is bound before passing pointers to the kernels.

bbe4435b19 minor API refactor of for EvalLimit :
- Replaced EvalData and EvalVertexData classes with a simpler DataStream class that only
  accesses a single data stream, binds and unbinds it

- DataStream has both an input and an output version which avoids much of the const-ness
  const-related ambiguity of the previous design pattern

- Vertex, varying and face-varying data now all have a dedicate struct (VertexData, VaryingData, FaceVaryingData)
  as a way of gathering the various data-streams required to perform sampling

- renamd some "Buffers" into "Tables" for better naming consistency with Far

54bef92aab switch cpuEvalLimitController to use a quad-tree based patch access map :
- remove PatchMap from FarPatchTables

- add a new FarPatchMap quad-tree class (constructed from FarPatchTables)

- refactor the EvalLimitController to use the quad-tree search instead of a
  serial loop access

c18cf5bff2 first pass at face-varying interpolation for CpuEvalLimit - still
a couple of kinks to be worked out...

043369485c - adding varying data interpolation to the EvalLimit module
- minor refactoring of the LimitEvalContext to accomodate all the data buffers

- pushing some minor sub-patch functionality back to FarPatchParams

- extend example code with randomly generated varying vertex colors

of bad parameterization on non-quad faces

85a3001120 Work in progress on EvalLimit : added Gregory & GregoryBoundary kernels.
Note : GregoryBoundary does not generate the correct surface yet (bug to be squashed soon)

f617cdd6ed Work in Progress : checkin in function kernels for boundary and corner patches.
Casual testing doesn't reveal any bug within our sample shapes.

Remaining : gregory & gregory boundary patches.

f25e89b745 Work-in-progress check-in for EvalLimit :
- added boundary / corner kernel code

- bug fixes for Gregory patch kernel

- wired the new kernels in the controller class

Note 1 : corner / gregory kernels are not working yet

Note 2 : the vertex mirroring solution used for boundary / corner kernels could be incorrect...

4bf24d9b95 First pass at our "Eval" API : this checkin is a mileston and is still missing
code paths for certain types of feature adaptive patches.

The check-in adds a new "limitEval" code example.

More to come soon...
