c7d986c7fe [kwin] Remove the legacy OpenGL 1 compositing backend
KWin already has a de facto OpenGL 2 dependency through QML. Combined
with the fact that the OpenGL 1 backend is basically unmaintained and
also unused, it's better to remove it for the new major release.

This change includes:
 * Removal of cmake option KWIN_BUILD_OPENGL_1_COMPOSITING
 * Removal of KWIN_HAVE_OPENGL_1 compile option and all code
   ifdef'ed with it (partially removal of if-else constructs)
 * Removal of CompositingType::OpenGL1Compositing (flags are kept
   as a core flag should get introduced)
 * Driver recommendation for OpenGL1Compositing changed to XRender
   (should be evaluated whether the drivers can provide GL2)
 * Removal of configuration option "GLLegacy"
 * Removal of fooMatrix function in kwinglutils
 * Removal of ARBBlurShader
 * Removal of legacy code path in GLVertexBuffer
 * Removal of GLShaderManager::disable
 * if-blocks with ShaderManager::instance()->isValid() removed

3f0ff9b8d5 Migrate effects from displayWidth()/displayHeight() to virtualScreenSize()/virtualScreenGeometry()
Rational behind this change is that displayWidth and displayHeight are
X specific API calls in kwinglobals. For the future it's easier to only
rely on functionality which goes through the EffectsHandler API which
allows easier adjustments in KWin core.

displayWidth() and displayHeight() are only used to get the size or the
complete rect of all screens. This is also provided by:

effects->virtualScreenGeometry() or
effects->virtualScreenSize()

76efe517a7 Turn built-in effects into a library kwin links against
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.

145f0c096f [kwin/effects] Do not use KActionCollections for the global shortcuts
Most effects had a "collection" for one action. We don't need the
action collection, all it was used for is setting the object name.

With the removal of KActionCollection the effects do not need to link
XmlGui any more, though the dependency is still pulled in through
plasma.

b7be3cb621 Better handling for making the compositing OpenGL context current
With QtQuick2 it's possible that the scene graph rendering context either
lives in an own thread or uses the main GUI thread. In the latter case
it's the same thread as our compositing OpenGL context lives in. This
means our basic assumption that between two rendering passes the context
stays current does not hold.

The code already ensured that before we start a rendering pass the
context is made current, but there are many more possible cases. If we
use OpenGL in areas not triggered by the rendering loop but in response
to other events the context needs to be made current. This includes the
loading and unloading of effects (some effects use OpenGL in the static
effect check, in the ctor and dtor), background loading of texture data,
lazy loading after first usage invoked by shortcut, etc. etc.

To properly handle these cases new methods are added to EffectsHandler
to make the compositing OpenGL context current. These calls delegate down
into the scene. On non-OpenGL scenes they are noop, but on OpenGL they go
into the backend and make the context current. In addition they ensure
that Qt doesn't think that it's QOpenGLContext is current by calling
doneCurrent() on the QOpenGLContext::currentContext(). This unfortunately
causes an additional call to makeCurrent with a null context, but there
is no other way to tell Qt - it doesn't notice when a different context
is made current with low level API calls. In the multi-threaded
architecture this doesn't matter as ::currentContext() returns null.

A short evaluation showed that a transition to QOpenGLContext doesn't
seem feasible. Qt only supports either GLX or EGL while KWin supports
both and when entering the transition phase for Wayland, it would become
extremely tricky if our native platform is X11, but we want a Wayland
EGL context. A future solution might be to have a "KWin-QPA plugin" which
uses either xcb or Wayland and hides everything from Qt.

The API documentation is extended to describe when the effects-framework
ensures that an OpenGL context is current. The effects are changed to
make the context current in cases where it's not guaranteed. This has
been done by looking for creation or deletion of GLTextures and Shaders.
If there are other OpenGL usages outside the rendering loop, ctor/dtor
this needs to be changed, too.

49e734f743 Change the way how effects can get mouse events
With the removal of BoxSwitch all effects which want mouse events use the
fullscreen input window. The available functionality is too complex both
in EffectsHandler and in the Effects.

With this change only fullscreen input windows are supported and all
effects share the input window. This means there is at maximum one input
window. This simplifies the code in the Effects as they don't have to
keep track of the window they created any more. In EffectsHandler it
means that only one window needs to be created, destroyed and raised.
Also it means that we can properly react on screen size changes which had
been ignored in the past. Also quite some roundtrips to X are no longer
needed as we do not need to query the window geometry when creating the
input window.

7a7f9d1a34 Change the way how screen edges interact with Effects/Scripts
The main difference is that the activation of an edge is no longer
broadcasted to all effects and scripts, but instead a passed in slot of
the Effect/Script is invoked.

For this the EffectsHandler API is changed to take the Effect as an
argument to (un)reserveElectricBorder. As callback slot the existing
borderActivated is used.

In addition the ScreenEdge monitors the object for beeing destroyed and
unregisters the the edge automatically. This removes the need from the
Effect to call unregister in the dtor.

18cccad806 Introduce a templated animationTime overload for the KConfigXT case
This method can be used to get the animationTime in case a configuration
class generated through KConfigXT is used. In general the configuration
stores the magic value 0 for a property "duration". This magic value
indicates that a hard-coded default value should be used.

So the common logic to test the stored value for 0 and then either pass
the stored value or the default value to animationTime is encapsulated
in this method in a generic way.

A MyEffect can use it in the following way:
animationTime<MyEffectConfig>(200);

cf5de22586 Introduce a build option KWIN_BUILD_OPENGL_1_COMPOSITING
If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.

This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.

With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.

E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);

while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);

Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.

c2a4f81927 Introduce a helper class to automatically push/pop Shaders
The ShaderBinder class can be used for the case that a block of code
should be executed with a given Shader being bound. This is useful for
all the cases where there is a if-block for OpenGL2 execution with a
Shader being pushed in the first line to the ShaderManager and popped in
the last line of the block. With the helper this can be simplified to:

ShaderBinder binder(myCustomShader);

or

ShaderBinder binder(ShaderManager::GenericShader);

The ctor of ShaderBinder pushes the given Shader to the stack and once
the helper goes out of scope it will be popped again from the stack.

In addition the helper can take care of OpenGL 1 compositing, that is it
just does nothing. So it can also be used where there is a shared OpenGL1
and OpenGL2 code path where the Shader should only be pushed in OpenGL2.
This basically removes all the checks for the compositing type before
pushing/popping a Shader to the stack.

f9a2ecbf33 Do not use ShaderManager::isValid to check for OpenGL2 compositing
The main usage of ShaderManager::isValid was to have OpenGL2 specific
code pathes. Now we have an actual OpenGL2Compositing type and we know
that the ShaderManager is valid if we have this compositing type and we
know that it is not valid on OpenGL1Compositing. This gives us a much
better check and allows us to use the isValid method just for where we
want to check whether the shaders compiled successfully.

In addition some effects require OpenGL2, so we do not need to check
again that the ShaderManager is valid. Such usages are removed.

Those new values are or-ed to OpenGLCompositing so that a simple check

values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.

The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.

f24103481e Ensure ScreenTransformation matrix is reset after rendering cube
Cube effect modifies the ScreenTransformation matrix. While each
window resets the matrix on a global level it's not reset. That
means if the last rendered window had the screen rotated the
ScreenTransformation keeps the rotation even after the cube
ended. This causes a rotated window in e.g. TaskbarThumbnails.

d14cf2da92 Show detailed information why an effect cannot be loaded
Effects can specify their minimum requirements in their
desktop file:
* OpenGL
* OpenGL 2 (GLSL required)
* Shaders (either ARB or OpenGL 2)

The configuration module uses this information in combination
with which backend KWin is currently using. So if e.g. OpenGL
is used and an effect requires OpenGL 2 a detailed error
message can be showed that OpenGL 2 is required.

d05d55b140 Delay creation of EffectFrames till needed
Creating an EffectFrame requires I/O which takes on my system
during testing between 10 and 40 msec. Also it needs a little
bit of memory.

This changes moves out the creation of EffectFrames at Effect
load till the Effect actually needs the EffectFrame. E.g. if a
user does not filter in PresentWindows there is no need to ever
create it.

BoxSwitch effect is ignored as it should be dropped for 4.9.

8489ede9aa Move loading of Cube textures into thread
Cube effect loads 0 to 2 textures which has been
performed during configuration. This change delays
loading the textures till cube is activated for the
first time and the loading from file is moved into
a thread.

This means that for a very short time the texture
is not yet visible, but this is not a problem as
the cube animates from fully opaque starting state.
So during the loading the texture would not be
visible anyway.

93b2674313 kwin: dropping several gl(Push|Pop)(Attrib|Matrix) calls
This makes kwin in OpenGL2 mode more coherent with kwin_gles.
Despite some fullscreen effects they should now make the same
(pure) OpenGL calls.

fe4329a252 Only call active effects in the effect chain
Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.

This change eliminates the hottest path inside KWin identified by
callgrind.

a05ad98896 Remove textureWidth/textureHeight from all Shaders
The uniforms textureWidth and textureHeight were only needed for
normal windows. For everything else it was just 1.0/1.0, that is
normalized.

The makeArrays method is changed to produce normalized texcoords
obsoleting the need for these uniforms. So two uniforms less, one
calculation in vertex shaders less and many many lines of code
removed.

At the same time makeArrays is also adjusted to take care of
yInverted of the texture, which is needed as we no longer can use
the enableUnnormalizedTexCoords which did the yInverted transformation.

32adc59e4b Use cap shader to render area between screens in cube
This fixes most of the rendering issues with cube in multi
screen setups and GLSL backend. For cylinder and sphere the
rendering of areas between screen is currently disabled if
using the GLSL backend. It needs adjustments to use another
vertex shader. Not sure if it is worth the effort.
