LibGfx: Implement Rect::to_rounded<U>()

Browse source 
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.
