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.
