Ensures KWin is also built with features disabled to catch when code is
added that requires a build-time guard

This commit expands the QImage-to-GL formatTable to include entries
for RGBX64, RGBA64_Premultiplied, and Grayscale16 image formats.
Uploading 16-bit-per-channel formats is supported by OpenGL and, with
the GL_EXT_texture_norm16 extension, GLES.
This ensures that we get a warning if the config header is not included
instead of compiling the code as if it was disabled. Interestingly, some
checks already used #if KWIN_BUILD_*, so those were generating -Wundef
warnings when the feature is disabled. Commit 886173cab assumed that all
those features were already 01, so this unbreaks the build if any of the
features is disabled.
Fixes: 886173cab ("Reduce ifdefs in Workspace::supportInformation()")
We should use the output area as the margin size as where to position
rather than the panelSize.
This ensures that the keyboard ends up in the right place right above
the panels.
This reverts commit 3d0bdc56a4.
seat->setFocusedPointerSurface() before notifyPointerMotion() is needed
to prevent sending a motion event that's outside the previously focused
surface.

It is automatically called (and documented as such) by KCModule
after the constructor is run.
This avoids calling a virtual method from the constructor.

Instead of having the render backends manage layers, have DrmGpu and DrmPipeline
do it. This makes it possible to unify code paths for leased and normal
outputs, remove some redirection and have more freedom with assigning layers
to screens.
It's leftover after the times when widget style was using wayland
connection. Breeze had to destroy all wayland resources before
terminating the internal connection.
Currently, the blur effect will shrink an opaque region even if it
doesn't intersect m_currentBlur.
This ensures that the blur effect won't do a stupid thing such as
clipping the opaque region of the desktop window.
We already try to ensure that the surface damage is within render target
bounds. Avoid clipping surface damage in render backend, which is a bit
excessive task and perhaps it should be done an abstraction level above.
If the main surface is translucent (e.g. it contains only the drop
shadow) but its subsurface is opaque, the "window->isOpaque()" check
will produce a false positive.
It's not guaranteed that there will be current render target in
postPaintScreen() as all painting have been completed. paintScreen() is
a much safer place to pick color.
It's not guaranteed that there will be current render target in
postPaintScreen() as all painting have been completed. Furthermore,
even the docs of the postPaintScreen() function indicate that no
painting should be done there, you can do only cleanup things, e.g.
schedule a repaint, etc. paintScreen() is a much safer place to
capture screenshot.
When casting from integer to pointer, promoting the integer to (u)intptr_t
will ensure that the resulting type can be converted to a pointer without
problems. These two casts changed in this commit trigger a warning when
building for CHERI-enabled architectures such as Arm Morello. This is not
just limited to CHERI, the cast from xcb_pixmap_t (uint32_t) to void*
should also be flagged by -Wint-to-void-pointer-cast when using Clang,
however, it appears that warning only handles C-style casts, and not
reinterpret_cast (https://github.com/llvm/llvm-project/issues/53964).
Software cursor has always been a major source of problems. Hopefully,
porting it to RenderLayer will help us with that.
Note that the cursor layer is currently visible only when using software
cursor, however it will be changed once the Compositor can allocate
a real hardware cursor plane.
Currently, software cursor uses graphics-specific APIs (OpenGL and
QPainter) to paint itself. That will be changed in the future when
rendering parts are extracted from the Scene in a reusable helper.
At this point, it's safe to assume that only X11 has weird rendering
model, which stands in the way of making rendering abstractions nice and
intuitive, so let's check operation mode. If OperationModeX11 is
dropped, this will also simplify finding X11-specific code in kwin.
This is the first tiny step towards the layer-based compositing in kwin.
The RenderLayer represents a layer with some contents. The actual
contents is represented by the RenderLayerDelegate class.
Currently, the RenderLayer is just a simple class responsible for
geometry, and repaints, but it will grow in the future. For example,
render layers need to form a tree.
The next (missing) biggest component in the layer-based compositing are
output layers. When output layers are added, each render layer would
have an output layer assigned to it or have its output layer inherited
from the parent.
The render layer tree wouldn't be affected by changes to the output
layer tree so transition between software and hardware cursors can be
seamless.
The next big milestone will be to try to port some of existing kwin
functionality to the RenderLayer, e.g. software cursor or screen edges.
The responsibilities of the Scene must be reduced to painting only so we
can move forward with the layer-based compositing.
This change moves direct scanout logic from the opengl scene to the base
scene class and the compositor. It makes the opengl scene less
overloaded and allows to share direct scanout logic.
