This replaces the usage of `rounded_int_rect`, whose name did not accurately reflect the rounding operation happening. For example, the position of the rect was not rounded but floored, and the size was pulled through `roundf` before casting to `int` which could result in inadvertent flooring if the resulting floating point could not exactly represent the rounded value.
