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 &

8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

Test Plan: Compiles.

3bbc9436db [kwin] Add a virtual Effect::requestedEffectChainPosition
This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.

Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.

7e10fe524f Fix warnings and compile errors when building with XRender Compositing disabled
ScreenEdgesEffect failed compiling, mouseclick and zoom are yelling
warnings.

Compiling is tested with XRender enabled, for the disabled test I need to
wait for my Jenkins installation ;-)

3d5f962566 XRender implementation for ScreenEdges Glow Effect
More or less straight forward port from OpenGL to XRender. There is one small difference:
the corners are not upscaled.
