Currently, the size and location of items displayed in Properties view are rounded value, but the real value written in the .Designer.cs isn't rounded at all.

This created some imprecision in size and location, possibly resulting in unwanted resizing of the report width, or in overlap.
Now, it is only possible to correct this in .Designer.cs, and the user don't see the problem without zooming at maximum or opening the .Designer.cs

Rounded value seems better than some unneeded decimal, but then the value displayed should also be written in the .Designer.cs
