[devjeonghwan]

Added cuda opengl headers and info codes for GL interop.

CUresult cuGLGetDevices ( unsigned int* pCudaDeviceCount, CUdevice* pCudaDevices, unsigned int  cudaDeviceCount, CUGLDeviceList deviceList )

Gets the CUDA devices associated with the current OpenGL context.

CUresult cuGraphicsGLRegisterBuffer ( CUgraphicsResource* pCudaResource, GLuint buffer, unsigned int  Flags )

Registers an OpenGL buffer object.

CUresult cuGraphicsGLRegisterImage ( CUgraphicsResource* pCudaResource, GLuint image, GLenum target, unsigned int  Flags )

Register an OpenGL texture or renderbuffer object.

CUresult cuWGLGetDevice ( CUdevice* pDevice, HGPUNV hGpu )

Gets the CUDA device associated with hGpu.
