Change opaque RS typedefs from void * to int. These will likely become...

typedef uint32_t uint;

//typedef uint64_t ulong;

typedef void * rs_element;

typedef void * rs_type;

typedef void * rs_allocation;

typedef void * rs_sampler;

typedef void * rs_script;

typedef void * rs_mesh;

typedef void * rs_program_fragment;

typedef void * rs_program_vertex;

typedef void * rs_program_raster;

typedef void * rs_program_store;

typedef int rs_element;

typedef int rs_type;

typedef int rs_allocation;

typedef int rs_sampler;

typedef int rs_script;

typedef int rs_mesh;

typedef int rs_program_fragment;

typedef int rs_program_vertex;

typedef int rs_program_raster;

typedef int rs_program_store;

typedef float float2 __attribute__((ext_vector_type(2)));

typedef float float3 __attribute__((ext_vector_type(3)));
