Add "check by overlap" process in the backgrounddColor processing

[WixeI]

Make the processing of background from children being passed to parent better.

Instead of just being passed from the last child, the condition is: the child that ocupies the biggest area of the parent AND has this area be at least 90% of the parent is the one who will pass its backgroundColor for the parent. If no child completes these requisites, the parent will retain its backgroundColor.

How to Test:
Have a component that has at least one child. Change the component type to "button", for example. The backgroundColor should remain the same unless one child occupies at least 90% of this component's area, then its background color should be passed to the parent.

I'm still having problems when changing the component type. Sometimes it works, sometime it doesn't. How should I proceed?

I tested a blue component with more than 90% of its parent (which had purple background), so when I changed the parent's type, the new background color was grey.
