// Some explanations for future readers:
// - The "height" as of writing of this entire widget is 2. If it's 1, it occasionally doesn't draw.
// - As such, the buttons are only on the lower part of this 2-high widget.
// - So, we want to only check at one location, the `draw_loc.y + 1`, and that's it.
// - But why is it "+2" then? Well, it's because I have a REALLY ugly hack
// for mouse button checking, since most button checks are of the form `(draw_loc.y + draw_loc.height)`,
// and the same for the x and width. Unfortunately, if you check using >= and <=, the outer bound is
// actually too large - so, we assume all of them are one too big and check via < (see
// https://github.com/ClementTsang/bottom/pull/459 for details).
// - So in other words, to make it simple, we keep this to a standard and overshoot by one here.
