/**
 * \brief \hl Returns a channel descriptor using the specified format
 *
 * Returns a channel descriptor with format \p f and number of bits of each
 * component \p x, \p y, \p z, and \p w.  The ::cudaChannelFormatDesc is
 * defined as:
 * \code
  struct cudaChannelFormatDesc {
    int x, y, z, w;
    enum cudaChannelFormatKind f;
  };
 * \endcode
 *
 * where ::cudaChannelFormatKind is one of ::cudaChannelFormatKindSigned,
 * ::cudaChannelFormatKindUnsigned, cudaChannelFormatKindFloat,
 * ::cudaChannelFormatKindSignedNormalized8X1, ::cudaChannelFormatKindSignedNormalized8X2,
 * ::cudaChannelFormatKindSignedNormalized8X4,
 * ::cudaChannelFormatKindUnsignedNormalized8X1, ::cudaChannelFormatKindUnsignedNormalized8X2,
 * ::cudaChannelFormatKindUnsignedNormalized8X4,
 * ::cudaChannelFormatKindSignedNormalized16X1, ::cudaChannelFormatKindSignedNormalized16X2,
 * ::cudaChannelFormatKindSignedNormalized16X4,
 * ::cudaChannelFormatKindUnsignedNormalized16X1, ::cudaChannelFormatKindUnsignedNormalized16X2,
 * ::cudaChannelFormatKindUnsignedNormalized16X4
 * or ::cudaChannelFormatKindNV12.
 *
 * The format is specified by the template specialization.
 *
 * The template function specializes for the following scalar types:
 * char, signed char, unsigned char, short, unsigned short, int, unsigned int, long, unsigned long, and float.
 * The template function specializes for the following vector types:
 * char{1|2|4}, uchar{1|2|4}, short{1|2|4}, ushort{1|2|4}, int{1|2|4}, uint{1|2|4}, long{1|2|4}, ulong{1|2|4}, float{1|2|4}.
 * The template function specializes for following cudaChannelFormatKind enum values:
 * ::cudaChannelFormatKind{Uns|S}ignedNormalized{8|16}X{1|2|4}, and ::cudaChannelFormatKindNV12.
 *
 * Invoking the function on a type without a specialization defaults to creating a channel format of kind ::cudaChannelFormatKindNone
 *
 * \return
 * Channel descriptor with format \p f
 *
 * \sa \ref ::cudaCreateChannelDesc(int,int,int,int,cudaChannelFormatKind) "cudaCreateChannelDesc (Low level)",
 * ::cudaGetChannelDesc,
