Touch screen support

[jinek]

Inspect already implemented controls for compatibility with touch screen.
CalendarPicker for example can not be clicked on empty area to expand the dropdown like ComboBox does.
Scrolling does not work.
ListBox does not allow selecting by empty area too, while it reacts to finger-down, not finger-up (is it correct?).
Difficult to scroll in TextBox.
Can we indicate that console enters text-input mode to bring up OSK?
Flayout in examples behave strange.
Think to hide blinking cursor when in touch mode.
