			* should be located on your system and for more details of its use:
			* http://www.khronos.org/registry/implementers_guide.pdf
			*
			* This file should be included as
			* #include <KHR/khrplatform.h>
			* by Khronos client API header files that use its types and defines.
			*
			* The types in khrplatform.h should only be used to define API-specific types.
			*
			* Types defined in khrplatform.h:
			* khronos_int8_t signed 8 bit
			* khronos_uint8_t unsigned 8 bit
			* khronos_int16_t signed 16 bit
			* khronos_uint16_t unsigned 16 bit
			* khronos_int32_t signed 32 bit
			* khronos_uint32_t unsigned 32 bit
			* khronos_int64_t signed 64 bit
			* khronos_uint64_t unsigned 64 bit
			* khronos_intptr_t signed same number of bits as a pointer
			* khronos_uintptr_t unsigned same number of bits as a pointer
			* khronos_ssize_t signed size
			* khronos_usize_t unsigned size
			* khronos_float_t signed 32 bit floating point
			* khronos_time_ns_t unsigned 64 bit time in nanoseconds
			* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
			* nanoseconds
			* khronos_stime_nanoseconds_t signed time interval in nanoseconds
			* khronos_boolean_enum_t enumerated boolean type. This should
			* only be used as a base type when a client API's boolean type is
			* an enum. Client APIs which use an integer or other type for
			* booleans cannot use this as the base type for their boolean.
			*
			* Tokens defined in khrplatform.h:
			*
			* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
			*
			* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
			* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
			*
			* Calling convention macros defined in this file:
			* KHRONOS_APICALL
			* KHRONOS_APIENTRY
			* KHRONOS_APIATTRIBUTES
			*
			* These may be used in function prototypes as:
			*
			* KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
