3d43f8ad93 Drop QGraphicsView classes in PaintData
QGraphicsRotation and Scale are QObject wrappers. It's not useful in
data structures where we're creating mulitple of these every frame. It's
large enough to appear in hotspot as taking over 1% of a regular frame.

We don't even use the QGraphicsRotation mapping inside scene for a
reason, so it's not giving us much.

It's technically an API break in libkwineffects. Pragamatically no-one
would use these. We also lose QGraphicsScale's origin, but we never
exposed this in PaintData's public header.

c3eba1e41c scenes/opengl: Do not process window thumbnails with lanczos filter
If window thumbnails have to be downscaled, it's up to the application
what filter must be used. Also, we don't really use the lanczos filter
because both x and y scale factors are 1.

74391e250e Store repaint regions per individual screen
AnimationEffect schedules repaints in postPaintWindow() and performs
cleanup in preScreenPaint(). With the X11-style rendering, this doesn't
have any issues, scheduled repaints will be reset during the next
compositing cycle.

But with per screen rendering, we might hit the following case

    - Paint screen 0
    - Reset scheduled repaints
    - AnimationEffect::prePaintScreen(): update the timeline
    - AnimationEffect::postPaintScreen(): schedule a repaint

    - Paint screen 1
    - Reset scheduled repaints
    - AnimationEffect::prePaintScreen(): destroy the animation
    - AnimationEffect::postPaintScreen(): no repaint is scheduled

    - Return to the event loop

In this scenario, the repaint region scheduled by AnimationEffect will
be lost when compositing is performed on screen 1.

There is no any other way to fix this issue but maintain repaint regions
per each individual screen if per screen rendering is enabled.

e5b2fca409 scenes/opengl: Use GL_CLAMP_TO_EDGE wrap mode with sw cursor
We use the GL_LINEAR magnification filter. This means that GL_REPEAT
wrap mode cannot be used for the software cursor because sampling texels
beyond the right texture edge is the same as sampling texels on the
left edge. This may produce undesired visual artifacts.

c8eeefbd7d platform/drm: Fix clipped HiDPI hardware cursors
If an output is rotated, we will compute a transform matrix for the
cursor plane to rotate its contents.

In order to compute that matrix we need the rect of the cursor in the
device-independent pixels, the scale factor and the output transform.

The problem is that we provide a rect of the cursor in the native
pixels. This may result in the cursor being partially or fully clipped.

4a0128cac1 Clip software cursors
If you play some video and the software cursor doesn't hover it, then
the shadow cast by the cursor will be getting darker and darker with
every frame.

The main reason for that is that kwin paints the software cursor even
if the rect behind it hasn't been damaged or repainted.

9b09f0399f Mark the cursor as rendered after performing compositing
If a cursor animation is driven purely by frame callbacks and kwin
uses hardware cursors, the cpu usage may spike to 100%.

This change addresses that issue by sending frame callbacks after a
compositing cycle has been performed.

9c20df5030 screencast: Use fences to avoid stalling the graphics pipeline
Currently, we use glFinish() to ensure that stream consumers don't see
corrupted or rather incomplete buffers. This is a serious issue because
glFinish() not only prevents the gpu from processing new GL commands,
but it also blocks the compositor.

This change addresses the blocking issue by using native fences. With
the proposed change, after finishing recording a frame, a fence is
inserted in the command stream. When the native fence is signaled, the
pending pipewire buffer will be enqueued.

If the EGL_ANDROID_native_fence_sync extension is not supported, we'll
fall back to using glFinish().

eeeac04974 Implement EGL_KHR_partial_update and EGL_EXT_swap_buffers_with_damage
Summary:
Notify the driver about the parts of the screen that will be repainted.
In some cases this can be benefitial. This is especially useful on lima
and panfrost devices (e.g. pinephone, pinebook, pinebook pro).

Test Plan:
Tested on a pinebook pro with a late mesa version.
Basically I implemented it, then it didn't work and I fixed it.
Maybe next step we want to look into our damage algorithm.

1fb9f6f13a Switch to SPDX license markers
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

9e797cf943 [scene] Introduce helpers for mapping between different coordinate spaces
We currently deal with three distinct coordinate spaces - the window
pixmap coordinate space, the window coordinate space, and the buffer
pixel coordinate space.

This change introduces a couple of helper methods to make it easier
to map points from the window pixmap space to the other two spaces.

The main motivation behind the new helpers is to break the direct
relationship between the surface-local coordinates and buffer pixel
coordinates for wayland surfaces.

f2c8981f7e [scene] Generate window quads for sub-surfaces
No window quads are generated for sub-surfaces right now. This leads to
issues with effects that operate on window quads, e.g. magic lamp and
wobbly windows. Furthermore, the OpenGL scene needs window quads to
properly clip windows during the rendering process.

The best way to render sub-surfaces would be with a little help from a
scene graph. Contrary to GNOME, KDE hasn't developed any scene graph
implementation that we could use in kwin. As a short term solution, this
change adjusts the scene to generate window quads.

Window quads are generated as we traverse the current window pixmap tree
in the depth-first search manner. In order to match a list of quads with
a particular WindowPixmap, we assign an id to each quad.

e4b598ca86 [scene] Build window pixmap trees before starting rendering
In order to generate window quads for sub-surfaces, we need a valid
window pixmap tree. The problem is that the window pixmap tree is
created too late in the rendering process. This change adjusts the
scene so it creates window pixmap trees before buildQuads().

66898e7f46 Wayland: Allow to take single screen screenshots using scale factor without loss
Summary:
The screenshot made on screens with scale factor were downscaled by their scale factor making them blurry.
It prevents taking screenshots of missing Hidpi related bugs showing the issues under Wayland.

This fix the case of a single screenshot, but not the rest:
Multiscreen screenshot downscales the screen using scale factor.
Spectacle rectangular selection screenshot is broken as soon as some scale factor different than 1 is used on any screen.

Test Plan:
Under Wayland with a scale factor on a screen, take a screenshot using spectacle.
The output image is not downscaled and has the same size as the screen resolution.

No other change to any other screenshot mode, or under X.

6abd23ed02 Make it possible to have a separate cursor for the tablet
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.

Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.
