Dunno if it helps here (probably not), but I have code that tiles (normal)
frames horizontally or vertically across/down the screen. The char-size
precision limitation you mention is not, at least for that application,
noticeable in practice. But I can see why it might matter more for "internal"
frames, which must fit exactly. FWIW, the code is here (commands
`tile-frames-*'):
