Increase fine-grained signals for some properties in Text
Text.[content/painted][Width/Height] were being always notified of
changes at bulk. This is can be harmful in performance of QML
applications that will trigger change requests on the program whenever
a property is modified.
This introduces separate signals so it's not a problem anymore.
