If another compositor changes the color encoding and color range properties, the
resulting colors will be wrong. This commit ensures they're always set to BT.709
limited range to prevent that
When a display gets turned off while a pageflip event was still pending, the pending
state gets changed immediately, without waiting for the pageflip event to arrive first.
When this happens, activePending() returns false, and so the pageflip event gets discarded.
This commit changes the logic to only check for activePending() when the pageflip is for a
modeset, avoiding that issue.

It's used as a float and otherwise it makes (some?) drivers very
confused as they're required to cast at runtime.
The original value is double so it makes sense to keep the same type.

As KWin measures render times properly now, these settings and estimations
should no longer be necessary, so this commit replaces them with one hardcoded
algorithm that should prevent most dropped frames and reduce latency
When sorting surfaces in the ancestor order we need to ignore null
surfaces.
In addition to that, we also need to properly handle the case where
a transaction with dependencies is unlocked and it contains null
surfaces.
For example, if there are three transactions A -> B -> C, and the B
transaction is unlocked, we cannot apply it until transaction A is
applied. The readiness check is based on checking the first pending
transaction of the surface. But if the surface is null, the check
will be skipped, which is not ideal as transaction B can be applied
before transaction A now. To address that, this change makes every
transaction entry remember the previous transaction. With that, the
readiness check can be performed even if the surface has been destroyed.

It doesn't make sense for a window to become 1x1 pixels small. When we have
server side decorations we also know that the decoration takes a lot of
space, so this commit enforces a bigger minimum size for decorated windows
BUG: 469237
Window::acceptsFocus() is not taken into account when a window is
activated using Workspace::activateWindow(). The main reason is because
of different input models on X11.
Instead, Window::takeFocus() should check itself if the window accepts
focus.
Right now the string is only set when the option is changed to anything
else. That's fine, but we need to set it on load too, or else the user
will see a placeholder string instead of the real text if they don't
change anything.

When testing whether or not a modeset is needed, all that gets tested is
whether or not the kernel would allow the commit to happen without the ALLOW_MODESET
flag. If there's properties that are only changed in DrmPipeline::prepareAtomicModeset,
we need to apply those in the next commit, regardless of whether or not
the ALLOW_MODESET flag is necessary.

Since hidden windows are not placed in the grid-like view, `cell.isReady` is always false for them, and they never switch to the "active-hidden" state when the effect is turned on. This commit makes sure that windows hide even if their cell isn't ready.
DrmPipeline::needsModeset, and by extension, DrmGpu::needsModeset is no
longer expensive in any way, so checking them multiple times per frame is
not a problem anymore
The DisplayPort multi stream path should be more stable in comparison to
connector names, so prefer that for differentiating between outputs with
the same EDID.
BUG: 470718
ICC profiles are now set through KScreen, which conflicts with colord. Colord is also
dropped because applications may read the profile for the current output from it, and
so KWin and the application both apply the profile, resulting in wrong colors.
While applications are still restricted to sRGB, this allows working on sRGB
content on displays with a wide color gamut as the whole profile gets applied,
instead of just the VCGT.
