Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
- add a limit evaluation method to EvalLimitController that allows
client code to directly pass the output buffer without binding it
to the Context (the call only computes vertex interpolation of a
single sample)
- switch the OsdUtilAdaptiveEvaluator to use the new method from the controller
and stop stomping member
- cleanup buffer and member variables no longer used
- cleanup initialization logic to be better aware of uniform / adaptive
- add some assert sanity checks in the cpuEvalLimitKernels
fixes#293
Prevent boundaryEdgeNeighbors[2] from being overrun when an interior
vertex has more than 2 boundary neighbor vertices. The fix is applied
to the GLSL / HLSL and CPU implementations.
Note: this appears to fix long-standing problems with Gregory patches,
but i am not entirely convinced that this fixes the general case.
fixes#259

- 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
- 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...
