Window manager hints are nothing special about emacs:

I don't see what would be the benefit of your approach.  What's the
value of being able to see half or quarter lines/columns?

Well, there's one case, where I can see it being useful, and that's when
images are shown in a buffer that also contains text, because images
occupy exactly one column/line, just like a huge glyph.  In contrast to
browsers, emacs doesn't use standard GTK or Qt canvas, where you get
that for free, but underly other restrictions which are more crucial to
emacs.

Bye,
Tassilo
