It's all in the specs (the WM documentation has been updated last week).
plane_blocks_per_line has been introduced in the update. X and linear
tiling uses plane_blocks_per_line as well, so a patch that introduces it
before this patch would make sense.
FWIW, the spec update is to deal with Y tile underflow in some cases,
which sounds like something we want.
