+ Projects the intersection of of the selections of src_space and

+ Non-negative on success/Negative on failure.
+ DESCRIPTION
+ Projects the intersection of of the selections of src_space and
+ src_intersect_space within the selection of src_space as a selection
+ within the selection of dst_space. The result is placed in the
+ selection of proj_space. Note src_space, dst_space, and
+ src_intersect_space do not need to use hyperslab selections, but they
+ cannot use point selections. The result is always a hyperslab
+ selection.
