Add do_row_3d for mipmapping 3D textures
Previously 3D textures were mipmapped using multiple passed through
the 2D mipmap generation code. This had 3 disadvantages. First, the
extra passes were slow. Second, this required the allocation of a
temporary buffer to hold intermediate data. Third, and most
important, the extra passes caused loss of additional bits due to
integer division / bit-shifting.
With this change, our mipmapgen conformance test passes for
non-compressed texture formats.
