`flip-y | rotate-N` transforms are equivalent to `flip-x | rotate-N`.
However, it is not intuitive to express transforms that flip the y axis
via flip-x transforms. This change adds convenience aliases to improve
code readability and keep code intuitive, which is going to be needed in
order to drop TextureTransforms flags.
Return the resulting value immediately than use moveLeft(),moveRight().
It makes no difference for QRectF, but it might be nicer for QRect which
would need to recompute the right and bottom coordinates twice.
I wanted to do this refactoring for a while but didn't do it due to the
lack of test coverage.
These can be useful in case a QRect needs to be mapped. One could
convert the QRect into a QRectF and then back to QRect, but given that
these conversion helpers are present in rendering hot paths, it would
be great to be more efficient and also potentially loosing precision
because of floating point arithmetic.
Instead of checking for fullscreen windows and deciding whether or not to schedule repaints
based on that, check if the active window is refreshing fast enough to be reasonable for vrr.
For automatic mode, vrr is also enabled with the active window instead of the direct scanout
candidate.

When returning back from direct scanout to compositing, the whole frame
has to be repainted because the most recent buffer in the EGL swapchain
contains outdated contents now.
This change works around it by purging the DamageJournal when scanning
out a buffer. However, a nicer solution would be to assign a unique
sequence number to every frame and use that to index the entries in the
DamageJournal. It's a nicer design. With such absolute frame numbers,
the DamageJournal could properly detect discontinueties.
Given the final release is in close proximity, this change doesn't go
after such a refactoring.
Most actions do not handle drag and drop properly yet (e.g. entering
the overview during drag and drop is just very broken), at least
allow "show desktop" and "application launcher".
This allows to easily drag a file onto the desktop by starting a drag,
nudging the "show desktop" screen edge and dropping it on the desktop.
Until night color is dealt with properly by adjusting the output whitepoint,
the channel factors have to be multiplied in with the color transformation
matrix manually

Most importantly, fall back to an assumption of 1000 nits peak brightness when the
max brightness is missing, instead of the sdr brightness, which causes more immediately
visible issues.
Ideally the user should configure this value in the display settings, but it's too
late to still do that for Plasma 6.0.
