Same code for qh_setsize [qset.c] and QhullSetBase::count

Performs a vector copy. @param[out] dest The result. [(x, y, z)] @param[in] a The vector to copy. [(x, y, z)]

In-place resize of image dimensions (cropping).

\returns a vector expression of the \a i -th column, * only the meaningful part is returned. * \warning the internal storage must be colum

Return iterators.

the return value is a type that can be converted to an iterator the reason for doing this is that it's not free to find the iterator pointing at the n
