SUMMARY

When using "Peek At Desktop", the empty desktop is displayed. When now the grid effect is opened, the last opened window shows suddenly up for a short fraction, same when closing the effect again. This is visually not pleasant. 
It'd be nice, if the window heap effects would consider the status of the "peek effect".

Please see the screen recording.

Merge desktop grid and overview together with a new three-state design

Merges the desktop grid and overview effects together in a new three-state one;
you can switch between them with a certain shortcut or gesture, and you can also
still access either the desktop grid or overview directly.

Default shortcuts are also updated to be Meta+G for Grid, Meta+W for Overview,
Meta+Tab to switch between the three states and Meta+Shift+Tab to cycle in the
opposite direction.
