c424594625 Major step towards consistent use of include paths in source files:
- changed the main OPENSUBDIV_INCLUDE_DIR to exclude ./opensubdiv
    - updated CMakeLists.txt files in non-examples to use only this path
    - updated CMakeLists.txt files in examples to append ./opensubdiv to path
    - updated source in regression/common to use #include <opensubdiv/...>
    - updated source in examples/common to use #include <opensubdiv/...>
    - deferred source in examples to be updated on a case-by-case basis

bd3113e7e3 spelling phase 4 -- examples, tutorials, regression tests
Read all comments and made corrections to files that aren't part of
OpenSubdiv itself but are packaged with it.

Commandline output of glPtexViewer is affected. Otherwise no functional
changes.

261dc17f1b OpenGL init without errors, example cleanup
The GLFW context version hint is a minimum version, not maximum version so
requesting 4.4 and then falling back to lower versions doesn't make sense.

This change sets the minimum version to 3.2 and attempts to standardize this
across all example apps.

Also print the maximum supported GL version along with the context version
at startup.

89dcea57c2 Fix CMakeLists: make project-relative include path overridable
All examples, regression tests and tutorials directly looked into
opensubdiv source directory to grab the header files. This is somewhat
convenient during development but they can mistakenly access private
header files.

With this change, when OPENSUBDIV_INCLUDE_DIR is given to cmake,
it will be used as an include search path to build examples etc.
Otherwise it follows the same behavior as before.

Also replaces include references to the files in regression dir
to be relative, and cleanups some copy-paste patterns.

541aeddd3a Osd API refactor: EvalStencils and EvalPatches
Add EvalStencils and EvalPatches API for most of CPU and GPU evaluators.

with this change, Eval API in the osd layer consists of following parts:

- Evaluators (Cpu, Omp, Tbb, Cuda, CL, GLXFB, GLCompute, D3D11Compute)
  implements EvalStencils and EvalPatches(*). Both supports derivatives
  (not fully implemented though)

- Interop vertex buffer classes (optional, same as before)
  Note that these classes are not necessary to use Evaluators.
  All evaluators have EvalStencils/Patches which take device-specific
  buffer objects. For example, GLXFBEvaluator can take GLuint directly
  for both stencil tables and input primvars. Although using these
  interop classes makes it easy to integrate osd into relatively
  simple applications.

- device-dependent StencilTable and PatchTable (optional)
  These are also optional, but can be used simply a substitute of
  Far::StencilTable and Far::PatchTable for osd evaluators.

- PatchArray, PatchCoord, PatchParam
  They are tiny structs used for GPU based patch evaluation.

(*) TODO and known issues:
- CLEvaluator and D3D11Evaluator's EvalPatches() have not been implemented.
- GPU Gregory patch evaluation has not been implemented in EvalPatches().
- CudaEvaluator::EvalPatches() is very unstable.
- All patch evaluation kernels have not been well optimized.
- Currently GLXFB kernel doesn't support derivative evaluation.
   There's a technical difficulty for the multi-stream output.

109a3f5383 osd layer: Add GLPatchTable and retire DrawContext
In osd layer, we use GLPatchTable (D3D11PatchTable) as a
device-specific representation of FarPatchTables instead of
DrawContext. GLPatchTable may be used not only for drawing
but also for GPU eval APIs (not yet supported though.
We may add CudaPatchTable etc as needed).

The legacy gregory patch drawing buffers are carved out to
the separate class, named GLLegacyGregoryPatchTable.

Also face-varying data are split into client side for now, until
we add new and more robust face-varying drawing structure
(scheduled at 3.1 release)

Tentatively replicate PatchArray structure in GLPatchTables. It will
be revised in the upcoming change.

Shifting hard-coded SRV locations of legacy gregory buffers in HLSL shaders.

c3aa00e706 remove SupportsAdaptiveTessellation from OsdDrawContext, and example cleanups
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.

4a4322983f Osd drawing API refactoring.
Remove DrawRegistry from osd layer and put a simple shader caching
utility into examples/common. osd layer only provides patch shader
snippet and let client configure and compile the code. Clients also
maintain the lifetime of shader object, which is preferable for the
actual application integration.

update all examples to use the new scheme.

b66380ee52 Refactor Osd::DrawContext
Since unified shading work already removed subPatch info from
Osd::PatchDescriptor, the difference between Far::PatchDescriptor and
Osd::PatchDescriptor is just maxValence and numElements. They are used
for legacy gregory patch drawing.

Both maxValence and numElements are actually constant within a topology
(drawContext). This change move maxValence to DrawContext and let client
manage numElements, then we can eliminate Osd::PatchDescriptor and simply
use Far::PatchDescritor instead.

This is still an intermediate step toward further DrawRegistry refactoring.
For the time being, adding EffectDesc struct to include maxValence and
numValence to be maintained by the clients. They will be cleaned up later.

The side benefit of this change is we no longer need to recompile regular b-spline
shaders for the different max-valences.

33bfbf699b Refurbish osd layer API.
In OpenSubdiv 2.x, we encapsulated subdivision tables into
compute context in osd layer since those tables are order-dependent
and have to be applied in a certain manner. In 3.0, we adopted stencil
table based refinement. It's more simple and such an encapsulation is
no longer needed. Also 2.0 API has several ownership issues of GPU
kernel caching, and forces unnecessary instantiation of controllers
even though the cpu kernels typically don't need instances unlike GPU ones.

This change completely revisit osd client facing APIs. All contexts and
controllers were replaced with device-specific tables and evaluators.
While we can still use consistent API across various device backends,
unnecessary complexities have been removed. For example, cpu evaluator
is just a set of static functions and also there's no need to replicate
FarStencilTables to ComputeContext.

Also the new API delegates the ownership of compiled GPU kernels
to clients, for the better management of resources especially in multiple
GPU environment.

In addition to integrating ComputeController and EvalStencilController into
a single function Evaluator::EvalStencils(), EvalLimit API is also added
into Evaluator. This is working but still in progress, and we'll make a followup
change for the complete implementation.

-some naming convention changes:
GLSLTransformFeedback to GLXFBEvaluator
GLSLCompute to GLComputeEvaluator

-move LimitLocation struct into examples/glEvalLimit.
We're still discussing patch evaluation interface. Basically we'd like
to tease all ptex-specific parametrization out of far/osd layer.

TODO:
-implments EvalPatches() in the right way
-derivative evaluation API is still interim.
-VertexBufferDescriptor needs a better API to advance its location
-synchronization mechanism is not ideal (too global).
-OsdMesh class is hacky. need to fix it.

420473b45b Experiment separating out Ptex from TopologyRefiner.
Remove the ptex-specific code from the Far::TopologyRefiner and instead provide it in a separate class Far::PtexIndices.  Clients who need to use the Ptex API need to first build a Far::PtexIndices object by providing it with a refiner.

This has the advantage of keeping the API on the TopologyRefiner a little cleaner.  The ptex methods were const but were mutating state with const_casts.  The new mechanism still achieves the same lazy initialization behavior by forcing clients to instantiate them exactly when needed.

A disadvantage of this approach is that the PatchTablesFactory creates its own PtexIndices and throws it out after the patch tables are created.  This is great if you're never going to need the ptex indices again, but not so great if you will need them again.
