The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Summary:
* Drop abstract BlurShader class
* Delete evil "using namespace KWin"
* Fix includes
* Use smart pointers
* Turn BlurShader into a QObject
* Fix coding style
* Add missing default cases
* Use default member initialization
* Delete methods that are used only once
* Use more const
* Use QRect::{top,right,bottom,left} methods in the setBlurRect method

Summary:
On wayland blur on secondary monitor would not render correctly.
BUG: 393723
Depends on D12452
Test Plan:
- use more than one output
- log in in a wayland session
- open a transparent window (for example: Konsole with transparent and blur enabled profile)
- drag the window to another screen
- blurs the content under the window corretly

Summary:
Added the option to turn on noise behind the blurred area.
The lowest strength value disables it completely, so it is optional and is disabled by default.
Test Plan:
Edit: this new screenshot shows the updated noise generation.
Edit2: separated the screenshots so you can flick through them to clearly see the differences

Summary:
Updated the old and outdated blur method to use the much more efficient dual kawase blur method.
Now with this we can do virtually infinite blur with very very little performance cost.
The dual kawase blur method is basically downscaling and upscaling an image, but combined with the kawase blur shader.
Comparison: https://i.imgur.com/mh6Cw61.png
Left is old, right is new.
Comparison was done with the strongest blur setting in a VM running on an Intel i7-4790 and a GTX980
We can see here that the performance is even better with this new method.

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
REVIEW: 116042
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()

* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
The logic has already ensured that the ARBBlurShader can only be used
when using the OpenGL1 compositor, the OpenGL 2 compositor needs to use
the GLSLBlurShader.
This change moves the complete ARBBlurShader into a KWIN_HAVE_OPENGL_1
ifdef section.
As a side-effect the ::create method can now return a NULL pointer which
makes more sense then returning an ARBBlurShader in case that the
GLSLShader is not supported.

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.
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.
This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.

QMatrix4x4 accepts data in row-major order, but returns them in
column-major order, which is not documented and because of that
I expected them to be in row-major order.
This commit fixes it and rewrites the shaders to apply the matrix
multiplications in the right order.
REVIEW: 100759
It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.
This allows using Lanczos filter also on systems not supporting GLSL.

This makes the blending work correctly when the alpha bits are zero,
which is apparently the case with NVidia.
