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.

876cf3bc86 fix GLFW problems with ptexViewer and paintTest 
GLFW 3.0.1 made the reshape callback explicit. Since we are using it to setup some framebuffers,
we need to call this function ourselves before starting the main-loop.

- fix FindGLFW.cmake to match the new locations

- fix all viewer & examples to build with 3.0, 3.0.1 and 3.0.2

Note : ptxViewer and paintTest do not work with 3.0.1 and 3.0.2 (yet)

f91ac77711 Fix Gregory patches for bad heptagon geo. 
Gregory patch shaders rely on a correct estimate of the maximum valence of the vertices in the mesh.

In the current feature adaptive analysis, we stop at level 1, the center vertex of the heptagon is
never traversed, and its high valence is therefore not recorded. The fix is to take advantage of the
first pass and use the number of vertices in the coarse faces to catch those high-sided non-quads that
would generate high valence vertices that may not be revisited in the second pass.

dae55d68e2 fix FarPatchTables::GetNumFaces() and FarPatchTables::GetFaceVertices() : 
These functions are exclusive to uniformly subdivided topology. With the recent refactoring
of PatchTables and the generalization of topology, uniform meshes only retain the topology
of the highest level of subdivision by default. These functions are now fixed to reflect the
change.

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

cf13a8d755 Add check in shape_utils that detects dicsonnected vertices in a shape mesh and exits with an error message. 
A more permanent fix will be to handle fully non-manifold topology at the Hbr level, but that is beyond the
scope of fixing this problem.
