Summary: The Show Paint effect is useful when debugging repaint regions issued by effects. The only headache with it is necessity to enable/disable it. Consider the following workflow: * Do some change to an effect; * Compile KWin (or the effect); * Go to System Settings and enable the Show Paint effect; * Test effect, check repaint regions, etc; * Disable the Show Paint effect; * Go to the step 1. This workflow is really exhausting. Also, when testing repaints in a nested compositor, things become quite messy. Because purpose of this effect is to debug repaints (and because this effect is not meant for daily usage), I think that's fine to change how it's activated. This patch improves the workflow by changing the way how this effect gets activated. Instead of enabling/disabling it, one can just use a shortcut to activate or deactivate the effect.
