#X text 143 15 transforms a dim[a... \, b] grid into a dim[a... \,
b-1] grid. there is a projection plane perpendicular to the last axis
and whose position is given by the creation argument. each vector's
length is adjusted so that it lies onto that plane. then the last dimension
of each vector is dropped;
