e144748c7a Add some const &
Summary:
Won't make things go much faster since everything that was
being passed by value is refcounted but still const & is a bit faster
than refcounting

For shared pointers instead of adding const & we move them into the
destination variable saving some cpu usage but at the same time making
clear the pointer is being stored by not being const &

1de9648a89 [effects/showpaint] Use a shortcut to toggle the effect
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.

cc1f30b43d [effects/showpaint] Modernize code
Summary:
Summary of changes:
* Use QVector to store colors
* Add Q_OBJECT macro
* Port away from QRegion::rects
* Fix coding style
* Use default member initialization
* Use nullptr
* Reserve rects in paintXrender

The behavior of this effect haven't been changed, it still acts as before.

Test Plan: Compiles, and the Show Paint effect is still a psychedelic thing.

846496d2c1 Cleaned up the effects/ directory by moving each individual effect into
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
