fpGUI is not a problem as they are not native, you can draw whichever
you want, but lost other capabilities inherited from the native system
like the syntetic read for impared people.

More or less :) Mostly is tell to GTK2 that I'll paint something over
TEdit and please GTK do not erase it :) or I "you" do it let me know
to repaint my own content.
