The added `#` prevents clang-format from misinterpreting the meaning of this statement and thus messing up the formatting of the next lines up until the first `layout` statement. Similarly, a semicolon is now enforced on `versions` defines to prevent clang-format from messing up formatting and putting them all on a single line. Note: In its current state the code will ignore chained statements on a single line separated by a semicolon. Also removed some extraneous lines missed in previous style changes or added by mistake with said changes (e.g. after uniform definitions that clang-format messes up somewhat too, but we live with it).
