According to experimentation with UIStringDrawing, this can actually return a CGSize whose height is greater
than the one passed in. The two cases are as follows:
1. If the given size parameter's height is smaller than a single line, the returned value will
be the height of one line.
2. If the given size parameter's height falls between multiples of a line height, and the wrapped string
actually extends past the size.height, and the difference between size.height and the previous multiple
of a line height is >= the font's ascender, then the returned size's height is extended to the next line.
To put it simply, if the baseline point of a given line falls in the given size, the entire line will
be present in the output size.
