For the float-aware Point class, a rounding mode has been introduced to store in which way the Point needs to be rounded when necessary. For rectangles, this has not been implemented yet and is added by this change. It also correct the way in which rectangle values are rounded by considering the top-left and bottom-right corner instead of top-left corner and width/height, also done in the Win32DPIUtils. So it streamlines the rounding behavior in Win32DPIUtils and the Rectangle class to uniformly scale the upper left and bottom right corner of a rectangle.
The changes also makes proper use of the floating-precision coordinates in the point/pixel conversions for rectangles in the Win32DPIUtils.
