It reduces the amount of manual OpenGL code, and it's better to use
ImageItem because that way the ItemRenderer will take care of snapping
to the pixel grid or colorspaces.

It's needed to properly render transformed overlay items. Ideally, the
ItemRenderer would split items that can be rendered with and without the
scissor test on its own. But we are not there yet, so pass the
PAINT_SCREEN_TRANSFORMED flag to force the ItemRendererOpenGL to use
hardware clipping.
The environment variable is primarily meant as a workaround for displays
and drivers that misbehave when more than 8 bits per color is used. To simplify
the code, this commit makes the environment variable only control the bpc
used for displays, instead of also controlling which buffer formats get
used.
The InputPanelV1Window doesn't actually need popupOffset(). Its popup
positioning is not data driven like xdg-positioner. It will be simpler
and more readable to compute the desired popup geometry explicitly.
The main motivation behind this change is to make the glide effect stop
setting a custom projection matrix in order to assist with making the scene
2d only.
The brightness of the screen is read from the luminance tag, and through
the color management protocol(s) passed to apps, so that they can adjust
their content accordingly
If the client is slow, kwin can receive _NET_WM_MOVERESIZE requests
after user has released mouse buttons. Ideally, the window manager
should refuse starting an interactive move/resize operation in such a
case so it's still possible to finish moving or resizing the window
by releasing mouse buttons.
If somebody else claims the selection, it's unclear what we should do.
kwin can't give up its selection as it's the one who is responsible for
window management and compositing. If anything, Xwayland should ensure
that no client can claim WM_S0.
Apparently, libepoxy requires a current EGL display in order to resolve
EGL functions. This is unexpected as most of the EGL functions require no
current opengl context.
This change makes kwin bypass libepoxy for problematic cases.

Quick tile mode reset should be done in the interactive move handler,
where the new move offset is set. Only reset it on resize to unsnap
the window from the tile.

This addresses an issue where mpv window with keep aspect ratio enabled
cannot be fullscreened due to constrainClientSize() returning size that
doesn't fit full screen area.
NOTE: This has been tested with 3440x1440 display and 1920x1080 video in
mpv.
Strict geometry disables certain user activites; full screen requests
and only sending configure events at sizes the client claims to support.
This was added as a workaround for xterm in 19 years ago. It's a client
side bug as applications can still choose to ignore the configure event,
so kwin shouldn't have to sanitise them in advance. xterm seems to have
fixed it's bug, and pragmatically we know not all window managers
perform these checks so most clients should not be relying on it.
On Wayland this additional check is proving problematic, the handling of
scaling especially fractional scaling is hitting cases where it's better
to always ask the client to do what kwin wants.
Tests that refer to sizeIncrements are dropped as they are only used in
the strict geometry passes which is being obsoleted. Resizing in general
is still tested.
BUG: 481456
Previously a tile could intersect with the tile next to it when resizing tiles in tiles-editor.
This checks that the tile next to the resized one is not at minimum size already, and stops
resizing if it is.
Do note that any current setups that may get broken if there is tiles that intersect each other,
so they may have to remake the tile setup.

The perspective projection matrix has its y axis flipped vertically. It
should be undone when applying the render target transformation, otherwise
the rotation order will be wrong.
