Testing of handling input in effects. This testing effect moves all windows
|
|
by 100 pixels down, creates an input window that'll intercept all mouse events
|
|
and activates the window that's been clicked (click position needs to be
|
|
transformed). This is useful for effects that present something on the screen
|
|
and let the user interact with it (e.g. a list of window thumbnails and the
|
|
user can activate the window by clicking its thumbnail).
