{ Thanks to using this button as a TUIControl descendant
(placing it on Browser.Controls list), VRML scene sensors
(like TouchSensor) will not intercept mouse clicks. That is, button
obscures anything clickable on VRML scene (like TouchSensor) underneath.
(If you would like to change this, you can set SampleButton.ExlusiveEvents
to false.)
(Images (TCastleImageControl) actually also obscure scene underneath, but since
they do not handle any keys or mouse by default, they let themn through
to 3d scene. This could be changed by overriding their
TCastleImageControl.Press etc.) }
