Analyze: Create Rectangle.OfFloat inside setters and getters of bounds, size, location, etc (points and pixels) for better precision

[amartya4256]

Description
With the reintroduction of old DPIUtil.scaleUp and scaleBounds, we need to enforce the Rectangle.OfFloat inside setters and getters of controls in win32 to make sure, they have better precision.

**Tasks: **

1. For every control, initialize rectangles in getters (points and pixels) with Rectangle.OfFloat.
2. For every setter of widgets make sure they convert the rectangle into Rectangle.OfFloat.
3. Provide a static method in Rectangle to convert rectangle to OfFlaot.
