Ability to reset inner width, height to 'auto'

[NamesMT]

There currently is no way to reset the inner width/height and widthTouched/heightTouched,
I.e: no way to make the component automatically scale again, forcing through css works look-wise, but will bugs the parent bound calculation.

Theres actually a "parent" issue that the inner width/height is not recomputed if the item inside could change it's size dynamically, so even if the current style is "auto", parent bound calculation is bugged after the item inside change it's size.
