Some window gravities require a division by two. Up to now,
test-gravity.c expected this division to always be rounded up. This
commit changes the code to also allow rounding down.

This adds a C program which tests if the window manager handles
gravities correctly. This program is loosely based on metacity's
test-gravity.c, but completely rewritten and this version does automatic
tests instead of allowing the user to perform testing by hand.
By having this as a self-contained C program, it is possible to compare
awesome's behaviour with the behaviour of other WMs.
In my testing, only metacity and awesome pass this test. This is not
that much of a big surprise since awesome was fixed in
https://github.com/awesomeWM/awesome/pull/505 to work correctly with
metacity's test-gravity.c. However, I am surprised that e.g. Fluxbox
gets this wrong.
