The left and right border images are rotated 90° before they are
uploaded into the atlas texture. The images are separated by a row
of transparent texels to minimize artifacts from oversampling.
With this change kwin renders the whole decoration with a single
call to glDrawArrays().
When this property is true, it indicates that the +U axis corresponds
to the +Y axis, and the +V axis corresponds to the +X axis.
This property is taken into account in WindowQuad::makeSubQuad().
It doesn't make sense to convert the extension names to QStrings.
This also replaces the QString parameter in hasGLExtension() with
a QByteArray and adjusts all callers.
Remove the manually written GL dispatch code, and use libepoxy
to resolve functions.
The only exceptions are GLX_MESA_swap_control, which is not in
the XML API registry, and GL_ARB_robustness/GL_EXT_robustness.
For the latter we want to resolve the functions to the same names
on both GLES and desktop GL, and plug in our own implementations
when the extension is not supported.
and copy isSpecialWindow() check as rulebook input
to setFullscreen()
Client::isFullScreenable() checks:
* fullscreen rule
* fullscreen_hack (-> for normal windows)
* geometry restrictions
* special window
Client::manage() for fullscreeining checks:
* fullscreen rule (with correct "initial" parameter)
* fullscreen_hack
-> this breaks the fullscreen rule for geometry restricted windows
and causes inconsistent behavior between client requests at runtime
(which do not test ::isFullScreenable()) and on mapping.
Otoh, the specialWindow() protection should apply generally - those
kind of windows should not be fullscreened since the user can not
exit this state via kwin for them - and there's hardly a good reason
for them to be fullscreen, esp. not to enter that state at runtime

It's possible that the rendering thread is still writing to the
buffer and if we destroy the buffer before it's finished KWin is going
to crash. So let's mutex lock the dtor to ensure that the rendering
thread finishes before we tear down the client.

Seems like porting to new infrastructure was incomplete. The
MaximizeRestore button consists of two buttons on top of each other with
an own mouse area in each and both always visible. This means the restore
button was stealing the mouse events of the maximize button breaking
maximization.
The solution is to have an additional MouseArea which controls the whole
button making the two button types just visualization.
This is going to be a controversal change. It enforces KWin decorations
on all client side decorated windows from GTK+. Unfortunately we are
caught between a rock and a hard place. Keeping the status quo means
having broken windows and a more or less broken window manager due to
GTK+ including the shadow in the windows. This is no solution.
Enforcing server side decorations visually breaks the windows. This is
also no solution. So why do it?
It's our task to provide the best possible user experience and KWin is
a window manager which has always done great efforts to fix misbehaving
windows. One can think of the focus stealing prevention, the window rules
and lately the scripts. The best possible window management experience is
our aim. This means we cannot leave the users with the broken windows
from GTK.
The issues we noticed were reported to GTK+ about 2 months ago and we are
working on improving the situation. Unfortunately several issues are not
yet addressed and others will only be addressed in the next GTK+ release.
We are working on improving the NETWM spec (see [1]) to ensure that the
client side decorated windows are not in a broken state. This means the
enforcment is a temporary solution and will be re-evaluated with the next
GTK release. I would prefer to not have to do such a change, if some of
the bugs were fixed or GTK+ would not use client-side-decos on wms not
yet supporting those all of this would be a no issue.
For a complete list of the problems caused by GTK's decos see bug [2] and
the linked bug reports from there.
The change is done in a least inversive way in KWin. We just check for
the property _GTK_FRAME_EXTENTS and create a Q_PROPERTY in Client for it.
If we add support for the frame extents in future we would also need
this. So it's not a change just for enforcing the decoration.
The actual enforcing is done through a KWin script so users can still
disable it.

This reverts commit c09d63d192.
The test results we got indicate that on NVIDIA the problems with the
threaded rendering loop do not exist and at the same time the rendering
result improves a lot. As Qt still disables the threaded rendering loop
for the problematic drivers, it's better to not force the basic rendering
loop.
As we have the split between Effects and Compositor settings nowadays
it's incorrect to have an Compositor related option exposed in the
Effects settings view. Thus the OpenGLErrorView should be removed. As
a nice side-effect that simplifies the main qml file quite a bit by
turning the EffectView from Item into Rectangle.
If it shows that we need the reset GL check in the effects view it would
be better to use a KMessageWidget like in the compositing view.

The position passed to core didn't take care of padding and that position
passed to decorationPos caused completely broken resize/moving behavior.
E.g. resize was started where it should have been moving, or jumping of
position when starting moving.

The KWin::Borders element is provided by an extension plugin. The reason
for that is to be able to use it from e.g. the kcm or Plasmate without
needing to compile the code in.
But this results in Aurorae itself not being able to access the element.
The solution is to first load our decoration plugin and afterwards
register the borders element again with the version compiled in from
Aurorae.
With that we can now read all borders and paddings without using
properties. Also we could connect to change signals and have the borders
and padding handling completely stateful. Might be an idea for extending
the decoration library...
Introduces partially checked checkboxes for Effects. If an Effect
has an enabled by default function and doesn't have an explicit
value in the config file the checkbox is set to partially. If there
is a value in the config, this will be used.
Clicking on Default will return to the partially checked state.
So far only the built-in effects support the partially checked state
and also the mutual exclusive groups do not support the partial checked
(main reason: RadioButton doesn't support it)

On MacBooks the "Exposé" button is on XF86LaunchA. Let's use it
for activating Present Windows (ALL) as an alternative shortcut.
For non-macbook users this doesn't hurt, for MacBook users it's a
nice touch to have the key working as indicated by the pictogram.
Yes, it's realy Key_LaunchC:
"On X11 this key is mapped to XF86XK_LaunchA key for legacy reasons."

Qt doesn't process the button release event for our moveresize window
wrapper. This means that Qt still thinks the button is pressed and breaks
a few things like one cannot enter another move/resize mode.

This servers two purposes.
1. it makes KWin/5 co-installable with KWin/4 as now binary and
all libraries etc. are renamed or installed to a different
location.
2. In future we need a dedicated X11 and Wayland main function
anyway. Thus it makes most sense to rename to kwin_x11 directly
instead of first renaming to kwin5. The reason why we need to
have dedicated main functions is that kwin needs to check early
whether X11 is working or Wayland is working. Right now the first
thing kwin does is trying to connect to the XServer. This happens
before the QApplication is constructed and before command line
args are processed. On Wayland we won't want to test whether we
can connect to the XServer. As it's too early to check whether we
are starting kwin for X11 or Wayland the most convenient way is to
have dedicated binaries - thus a rename is needed. Just renaming
kwin for wayland is also not a good idea as in future the "main"
kwin will be for wayland not for X11. Another case for the dedicated
binaries is the Application class, which right now first tries to
claim the X11 Window Manager Selection. Again on Wayland even with
XWayland we won't need that. KWin will be the window manager for
XWayland if KWin is the Wayland compositor. There is no need to even
try to support anything else. Most likely it will even be KWin to
start the XWayland server, so we can be sure that there is no other
WM running and thus no need to claim the selection and abort if it
fails.
