// This template traverses over all the entries of the mask matrix M, and
// operates on C(i,j) if the mask M(i,j) == 1, via the GB_MASK_WORK macro,
// where C(i,j) is at Cx [pC] and Cb [pC].  M is hypersparse or sparse.

// M has alreadly been sliced for parallel work.  The tasks are held in
// pstart_Mslice, kfirst_Mslice, klast_Mslice, M_ntasks, and the work is done
// by M_nthreads threads.

// The work done by this kernel is independent of Mask_comp; both M and !M
// do the same work by scattering their entries into the C bitmap.

// C is bitmap/full.  M is sparse/hyper, and can be jumbled.
