Floats in Columnsets

[Reimer Behrends <behrends@cse.msu.edu>]

It appears as though \placefigure doesn't work very well with columnsets
if the size of the floats isn't an exact multiple of the underlying
grid. More precisely, \placefigure and friends, when used with any of
the *tb and tb* options (tblr, tbrl, lrtb, rltb, fxtb) snap the bottom
of the figure to the grid rather than the top. Of course, that means
that most of the time figures will not be aligned at the top. (See below
for an example.)

Does anybody know of a fix or workaround for this problem?
