Fix for b/16400888 - API Review: GridLayout attributes

Column weights specify the relative proportions of space distribution
within a *row*. With that in mind, I flipped the vertical and horizontal
axes in the docs - but that was a mistake. This CL flips the docs back.
The code works the right way around so doesn't need to be modified.
