Apologies, second thoughts - why calling all this binding and properties
"virtual"? That's the word which immediately raises questions, because
bindings are only for real things, not virtual.

Touchscreen is just clipped, not virtual, so maybe "clipped-area"
instead of virtual-touchscreen? Buttons are real, so maybe just "buttons"?

Best regards,
Krzysztof
