Matrix-vector multiplication dimensionality mismatch in create_partition_by_restriction  #27

Description

@Anjiang-Wei

The current manual 4.3 Partition by Restriction (page 39) mentions that

The transform T is an n × m matrix, where n is the number of dimensions of the color space
and m is the number of dimensions of the region.
For a point p in the color space, the points in the corresponding subregion
are defined by the rectangle Tp + E.

The confusing part is that the color space is a n-dim point, T is a nxm matrix, and the notation Tp+E does not match the matrix-vector multiplication's dimensionality requirement. Either T has to be a mxn matrix, or the Tp+E should actually be T'p+E where T' is the transpose of T.
