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.

fixes #181

30ec963112 fix example code to work with GLFW 3.0
- 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)

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

419b6b9716 - add a message to limitEval when trying to display face-varying UVs on shapes
that do not have that type of data

- fix some regression shapes that had "empty" uv values
  (including some minor topo surgery that luckily appears to not break
  regression baselines)

cf1b2f1334 - fix a face-varying bug in shape_utils : now face-varying UVs are indexed correctly
coming out of our shape format

- set blue component of point-cloud to 0 in face-varying mode (save a few micro-secs)

f5a7ad4cdb evalLimit example : make sure to reset the output buffer on creation - some of the prims may not
set all the point colors (if face-varying data is missing on the test shape for instance)
and we don't want random values creeping from unset memory allocations.

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

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.

f2b3419a4d bug fix in limitEval example : calculation for the required number of samples was incorrect

393362b589 Cleaning up the feature adaptive patch colors : all example code now shares the same function to provide the patch colors

87114f7428 Rename osd_util to osdutil.
Cleanup the batching classes so that DrawCollection() no longer caches
current batch and effect. Any kind of binding optimization will be
handled in client's delegate class.
Also remove InitializeVertexBuffer method and add some arguments to
constructor instead.
