Summary:
This reverts commit 14d1fdf63f.
The zoom effect is definitely the wrong way, it's broken (can be
triggered without moving the mouse, expands windows outside of their
allotted area (looks like broken sizing/placement), isn't animated so
feels very choppy, isn't using well-known highlight semantics), the
result is that it feels unnatural and jarring. To be honest, when I
looked at it, I was looking for a bug in the code, e.g. margins not
being taken into account. It didn't come up in me that this could be
wanted behavior, until I read the code.
As to the original commit message: The highlight is useless for this
case, as any window can be dragged or activated, highlighted or not.
What *could* work is to somehow intensify the colors, but that again
would have to be animated, and play well with the ongoing desktop-zoom
animation, the mouse pointer location changes relative to the window, so
it's really complex to get right. I thought of this for a while, I don't
think the complexity that has to be implemented is worth the benefit,
because, what does highlighted really mean here? "window is under the
mouse" isn't a useful metric, as we don't know if the user is changing
desktops or rearranging windows, and "window under mouse" changes
depending on the zoom level, "window can be dragged or activated" also
isn't a useful metric, as I can do that with any window, anyway.
Test Plan: Tested with patch applied, desktopgrid windows don't jump around anymore.

A QEvent* is passed around, this could also be a QWheelEvent. Only
present windows static casted, all other effects verified.
Documentation is not existing, so we don't know what was intended.
even if scaled or translated, if WindowForceBlurRole is set
do the blur anyways
same thing for backgroundcontrast

this effect, derived from the Maximize one, will
take the place of the manual window position
animation that Plasma tooltip are using.
this should cause less problems as animationg
positions on X is very error prone, plus it's
less jarring when the tooltip sizes changes too,
since that gets animated as well (behavior similar
to Windows7 taskbar tooltips)

Effects which require mipmaps need to check for LimitedNPOT and
disable the functionality if only limited NPOT is available.
Ideally the effects could also check whether the texture they
operate on is a power of two, but that's a little overkill for
the rather uncommon setup.

If a window is fullscreen and wants fullscreen blur behind it, we
use the blur from logout effect. This is mostly intended for the
Application Dashboard which requires a fullscreen blur. The generic
blur effect is not designed for such usage and is rather costly.
This simplified blur just needs framebuffer blit and midmaps. This
makes it rather cheap in usage and also doesn't need a cached texture.

One resource is used for shader version 1.10 and one for version 1.40.
The ideas behind this change is to remove the locating of the shader
sources and also to fix that user provided shaders could be loaded
instead of the original ones (possible attack vector on Wayland).
To simplify the ShaderManager provides a new method call to load the
shader from the resource. This means the effects don't need to
duplicate the check for the shader version any more and also don't
need to duplicate the file reading functionality.

The blur effect so far calculated a custom model view projection matrix.
This is not needed as we have the current projection matrix available in
WindowPaintData and EffectFrame.

The blinking shader is adjusted to use a shader trait vertex shader
and gets generated with a shader trait variant.
Overall the code is simplified to ensure that we always have a shader
bound with the correct mvp matrix when rendering the icon.
In addition it's required to keep the expandedGeometry alive until
the effects handled the deletion

Most of those effects didn't need special screen locking handling on
X11 as they prevented screen locking. On Wayland though, we don't
want the lock screen shown on a cube.

the stackingOrderChanged() signal came before the window turned an effect window
usually this is no problem as the change shall not be caught anyway, but
the window may have changed its stack position

window wasn't correctly represented in
zoom, present windows and desktop grid effects
on the fly code streamlining:
- logout and above windows were handled equally in different code paths
- windows were painted on 0 opacity instead of just aborting the paint
local semi-paintdata because PaintData isn't assignable
(const dptr, I think) and we're post freeze.

Eg. if a window is closed while "timeline.currentValue() == 0",
slotWindowClosed() will shortcut exit and not be removed from the
managers, thus dangle around forever.
Maybe there're other ways for a window to be deleted w/o
the closed slot being entered.

stupid clients think it's relevant to withdraw other states
when going fullscreen, this means we trigger an
nmaximization animation and when that's done, the
window is fullscreen...
Unfortunately one of the stupid clients is QWidget and also
the window could get other, *legit*, resizes during the
animation, so we cancel it on occasion

For the functions from GL_FOO_robustness we want to resolve it by
ourselves in order to add a custom implementation if it's not available.
Unfortunately once epoxy.h is included this breaks as epoxy defines the
names and so through the preprocessor epoxy always wins.
So we need different names: all functions from robustness get a "kwin"
prefix and the usage is changed everywhere in kwin source code.

While the main plasma desktop containment does one
desktop per screen, that does not necessarily hold
for other containments, let alone other desktop shells
To indicate that the window is "active" ie. can
be dragged or activated (like in present windows)
There was either a bug or a forum post complaining
about the inability to activate windows from DG
They're only traversed and QHash is unordered - so
the worst container. Also we have complete control
over the maintained class, so we can just keep the
mapped EffectWindow there
esp. the list-remove icon looks like "delete" and
can cause worries about what happens to the windows
as a bonus, the buttons now follow the DPI. are a
little smaller (presently might fit touch devices? but
is way to huge on "normal" desktops with ordinary DPI)
and the buttons have nice visible animations on pressing

Also a leftover in the glide effect.

Basically dead code given that Plasma doesn't have a dedicated dashboard
mode anymore and also doesn't set the required window role for it to
work.
By deleting we save one string comparison for each newly opened window.

Following the approach how it's done for X11: only create the interface
if the shader succeeded to compile and remove support again if it failed
to compile after a reconfigure.

before, hiding the buttons relied on the effect
seeing a paint event for the (with a low timeline
value) what's too wonky at least for instant animations
(certain failure) or when effect exits immediatey

Theory:
----------
because PresentWindowsEffect::screenCountChanged() is shortcut
for "if (!isActive())", but the desktopgrid doesn't call
PresentWindowsEffect::setActive (or at least
PresentWindowsEffect::screenCountChanged), so the effect can
"miss" the increasing screen count change (it sees the signal,
but ignores it) and when desktopgrid calls it, it assumes the
m_gridSizes array is big enough (but it isn't)
Steps:
----------
1. effects are loaded, 1 screen present
2. 2nd screen gets added, but inactive effects ignore that
3. desktop grid gets activated, updates according to screen count,
calls presentwindows for screen #2
4. presentwindows data is only prepared for one screen from step 1
=> BOOM
