Reduce unnecessary vertical code alignment

Reduce unnecessary vertical code alignment

While it may look nice many times, it causes annoying merge conflicts.
Especially aligning all `require(...)` calls has bitten me many times, since
adding or removing one often requires reformatting the entire block.

This commit attempts to remove vertical alignment (especially around `=`) for
the sake of smaller diffs and simpler merges.

Vertical alignment has been kept, though, where it really makes the code easier
to read and you're likely to edit all of the aligned lines anyway if changing
one of them. The most common example is code dealing with X and Y coordinates
and having to do the same thing to both of them. Only the words X, Y, left,
right, top, bottom, width, height etc. differ between the lines. It's easier to
see that they are really up-to-date with each other if the common parts are
aligned.
