After introducing SurfaceExtension, SurfaceRole has lost its commit()
function. It serves informative purpose now only.
Shell surface implementations don't have to inherit from SurfaceRole.
By making SurfaceRole act more like a value type, it's possible to fix
role handling in wl_pointer.set_cursor.
There's "major" and "minor" defines that can get implicitly included, for
example with musl libc. To prevent that from breaking compilation, rename
the methods
Since there is now exist the signal right before maximize, use it to
set oldGeometry instead of storing previous values every time with
windowFrameGeometryChanged.
This fixes the effect under Wayland.
In many cases it's irrelevant, what we care about is whether given effect
is loaded and performs its function. So remove these paranoid checks
except the tests where it's important to use OpenGL compositing.
Instead, creating contexts that miss these features should fail directly,
making KWin fall back to software rendering.
While this commit also drops workarounds for broken drivers that do software
emulation for features we need, such workarounds belong into these drivers and
the user can still manually turn off compositing if needed.
This commit also drops most of the code around checks for direct rendering. If
direct rendering isn't supported, creating the OpenGL context will now simply fail,
achieving the same effect
In certain cases it can be useful to delay applying a surface commit. As
an example, the compositor may wait until the committed graphics buffer
is ready for reading to avoid stalling its graphics pipeline.
This change introduces basic surface state locking capabilities and
ports some surface extensions to new helpers to manage associated state.
Currently, committed fields are contiguously accumulated. With this, it
will be possible to see what fields have been committed when the
committed() signal is emitted.
It would be nice if xdg-surface and xdg-surface role state are in a
single object so it's easier to stash them. This change refactors
xdg-shell handling to allow that.
xdg-surface state now belongs to xdg-toplevel or xdg-popup state.
It makes no sense to lock that behind an env var. If there's errors those
should always be printed so that we know about them without further investigation
Avoids accidentally triggering an edge when dragging a scroll bar or
text selection all the way to the screen edge.
Special case for moving windows, as you want to be able to drag
a window to an edge to switch virtual desktops.
