Improved CocoonJS touch support: compatibility with user defined styles

Improved CocoonJS touch support: compatibility with user defined layouts or absolute positions. Now the input works fine if the user sets a style to the renderer view: renderer.view.style.cssText = "position:absolute;left:200px"; 

Tested Example 06: Interactivity demo in portrait/landscape with user defined styles or using CocoonJS full screen modes and the input is fine in all cases.
