00ce36433f Fixed handedness flip in Gregory{Basis} shaders 
There was an unnecessary double-flip in the shading calculations.

Add a HLSL version of GregoryBasis patch shader.

8d9ae550ff Add a HLSL version of GregoryBasis patch shader. 
hlslPatchGregoryBasis.hlsl is an equivalent to glslPatchGregoryBasis.
Update dxViewer to be able to switch among bspline, gregorybasis, legacy
end capping.

also fixes a bug of GLSL legacy gregory shader which had an inconsistent
resource naming with example codes.

It looks like there's still an issue of D3D11 patchParam data fetching.
we'll come back to that bug.

392e5e8bed Remove #pragma once 
While this may be worth revisiting, we should first quantify the benefits and
identify the compilers that support it. Ultimately, we may never use pragma
once in favor of strictly using standard C++.

b781c6efd3 Removed Hbr code from farViewer. 
The code in farViewer that was used to draw the Hbr representation
of meshes is now gone.  This code was mostly used as a way to compare
against the Vtr implementation.  However, we don't want this to serve
as an example for others as the Hbr code is not meant to be instructive
otherwise.

    - redefined obsolete TopologyRefiner methods in terms of TopologyLevel

b167096dd8 Fixed FindDXSDK to prefer more recent D3DCompile 
The most up-to-date version of the HLSL compiler is now shipped as part
of the Windows SDK. Previously, the HLSL compiler was included with
the DirectX SDK.

There is more that we can do to improve this cmake module, but this
makes it more likely to find the correct tool.

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.

a79dbcc074 Renamed vtrViewer to farViewer. 
The name change is motivated by the desire to reflect that Vtr is
private API and its functionality is exposed publically through Far.

948895369d update glShareTopology example. 
This examples is rewritten as a more comprehensive example
of Far and Osd APIs to generate batched index buffer and
vertex buffer, as well as sharing same topology and stencil
table among multiple objects.

Also this change includes an experimental code path of using
glMultiDrawElementsIndirect. It's currently incomplete due to
the missing interface of osd tessellation shader.

984aedf842 Changed default draw modes for dxViewer 
This restores the previous defaults and works around an
apparent runtime error on some platforms which is triggered
in the legacy gregory patch drawing code when patch culling
is disabled.
