I tested `window-text-pixel-size' mostly by switching forward and
backward between help buffers because these are the only ones here whose
text size is not an integral multiple of the nominal character size.  In
the course of testing I found some problems with help buffers and fixed
them on the fly.

Later, when I installed the pixelwise changes, I was afraid to back out
some related ones like the one we talk about here.  But note that the
bug which is the subject of the current thread was implicitly caused by
reverting a behavior erroneously introduced in Emacs 24.3 (see the
threads of bug#16816 and bug#17007 for details).

I think Stefan explained that meanwhile.
