I am trying to understand what you mean:

The font size is 13. Scale to 0.5 means 13/2 = 6, which means that
there are only 4 pixels available for the height of uppercase letters
like C. Is this right? You confused me a bit with 10/2 = 4, that's why
I am asking...

If that is correct, then rounding up in such cases could be a good
idea, i.e., 13/2 = 7. I just saw again that Jason mentioned that
already in this thread (or at
<URL:http://lists.gnu.org/archive/html/emacs-pretest-bug/2004-10/msg00210.html>).
