		const float	proj[4][4],

The same result could be obtained as follows:

float projinv[4][4];
invert_m4_m4(projinv, projview);
copy_v3_v3(r_world, in);
mul_project_m4_v3(projinv, r_world);

But that solution loses much precision. Therefore, get the same result without inverting the project view matrix.
