[Elisa] [PATCH] quit pigment examples with keyboard

[Thijs Vermeir]

Hello,

I' trying to use pigment/elisa in a keyboardless environment. When I
tried the pigment examples I could not quit these examples easily with
the keyboard.
The applied patch fixes this and allows quiting via the keyboard.

Gr,
Thijs
