X-KWin-Internal should be used for effects which are either internal
to KWin and are configured at a different location in KWin. Examples
are:
* CoverSwitch - configured in WindowSwitcher KCM, but not FlipSwitch
as that one has a non WindowSwitcher mode
* window geometry - configured in moving
And it should also be used for helper effects to the overall
kde-workspace module. Examples are:
* Dashboard - required by Plasma
* KScreen - required for KScreen
* Screenshot - required by KSnapshot
Why a new category and not the already existing NoShow property?
The idea is to just filter on the effects in the list. Thus it should
be possible to show them. But NoShow is clearly intended to not be
shown at all.

As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.
[1] QElapsedTimer around the loading code, start kwin five times, take
average.

That's what you get for changing code you cannot properly test. The
calculation was completely messed up. Now reads the correct byte size
for the byte array. In addition the usages in the effects are improved
to cast the data into the proper uint32_t values instead of the more
generic long. After all if the format is 32, the length is 32 and not
a long.
This effect is controlled by KScreen. It fades out all windows when
KScreen requests this and gives feedback to KScreen once all windows are
faded out. This allows KScreen to adjust the screens in a flicker free
way.
