d2abf61c56 Added adaptive tess of user varying values
This isn't necessarily a final design, but
it gets enough of the pieces in place to move
forward.

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

21b9fbbb95 Moving some member variables of OsdGlDrawContext from public to protected
and adding the requisite accessors

Note : all our example code goes through the same boiler-plate texture
binding code - we might want to move it as a member function of the DrawContext.
