[wish] method for panels

[timo]

Most of the time you don't want that a panel, for example a splash screen, remain premeable to commands that reside on the activity itself, like buttons, etc. If you put the panel enabled false , it remains permeable on unwanted touch trough it that affect what is under.

Naturally you can avoid this behaviour by code, but with complicated screen activities this is not very practical.

It should be nice to add a new method to panels (Layers too?) making them "permeable" true/false

Thanks
