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.

be759b7d33 Use AbstractClient instead of XdgShellClient wherever possible
Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.

In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.

Test Plan: Existing tests pass.

7d4471eba6 Rename geometry property to frameGeometry
Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.

This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

d92d6e77ae [autotests] Don't test wl-shell clients
Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.

Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.

The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

Test Plan: Compiles.

1ca2aec77f [wayland] Don't use hardcoded move-resize cursor
Summary:
Currently, when resizing a window the cursor doesn't match the resize
direction. The reason for that is the move-resize cursor is hardcoded.

To fix that, CursorImage::updateMoveResize has to use AbstractClient::cursor.
Also, because the move-resize cursor is updated after calling startMoveResize,
we have to connect to AbstractClient::moveResizeCursorChanged.

1e4703a719 [wayland] Confine pointer to screen geometry
Summary:
If the new pointer position is "off screen", PointerInputRedirection
just ignores that new position. So, pointer remains on its previous
position. In some particular cases, like reaching default panel, it
degrades desktop experience because one have to slowly move pointer in
order to reach what he/she wants.

This change addresses that problem by confining the new pointer position
to screen geometry.

e3250460cc Do not unset cursor image when cursor enters a surface
Summary:
From Wayland documentation:
"When a seat's focus enters a surface, the pointer image is undefined and
a client should respond to this event by setting an appropriate pointer
image with the set_cursor request."

KWin's interpretation so far for the undefined pointer image was to
remove the pointer image when entering a surface waiting for the client
to set a cursor image. This can result in a short flicker as there might
be a frame without a cursor image.

This patch changes the behavior by keeping the previous image till the
application set a new one. This brings some advantages:
 * if the application is not responding a cursor is still shown
 * if the same cursor is used as in the previous window we don't have a
flicker

CCBUG: 393639

Test Plan: I cannot see the flicker, so only tested with the adjusted tests

9a13743c49 Don't update the focused pointer Surface if a button is pressed
Summary:
During pointer motion we already had the condition that an update of
focused pointer surface can only happen when no button is pressed. But
there are more conditions where we try to update the focused pointer even
if a button is pressed. E.g. if the stacking order changes.

This happens when trying to move one of Qt's dock widgets:
 1. Press inside a dock widget
 2. Qt opens another window, which is underneath the cursor
 3. KWin sends pointer leave to parent window
 4. dock widget movement breaks

This change ensures that also this sequence works as expected and the
pointer gets only updated when there are no buttons pressed, no matter
from where we go into the update code path.

BUG: 372876

Test Plan: Dock widgets in Dolphin can be moved now.

1193b0da77 Initial support for popup window handling
Summary:
So far KWin did not properly handle popup windows. That is when a popup
surface got created and a click outside the surface happened KWin did not
send out the popupDone Wayland event.

This change makes KWin aware of whether a surface is a popup and tracks
through a new PopupInputFilter whether there are popup windows. In case
there are popups the new filter waits for mouse press events and cancels
the popups if the press does not happen on any surface belonging to the
same client. To quote the relevant section of the Wayland documentation:

    The popup grab continues until the window is destroyed or a mouse
    button is pressed in any other client's window. A click in any of the
    client's surfaces is reported as normal, however, clicks in other
    clients' surfaces will be discarded and trigger the callback.

So far the support is still incomplete. Not yet implemented are:
 * support xdg_shell popup windows
 * verifying whether the popup is allowed to be a popup
 * cancel the popup on more global interactions like screen lock or
   kwin effect

0bb587dcb9 Ensure PointerInputRedirection::processMotion finishes prior to warping
Summary:
Consider the following situation: we have three InputEventFilter linked
in the sequence A - B - C.

The input filters are processing pointer motion events. The expected
behavior is that the new motion is processed in the sequence
   A -> B -> C

So far this did not work correctly if the pointer gets warped during the
processing. If e.g. filter B warps the pointer we get a motion sequence:
   A (1) -> B (1) -> A (2) -> B (2) -> C (2) -> C (1)

The filters following the one warping the pointer get first the newer
than the older position. This is obviously wrong. Unfortunately it is not
just a theoretical condition, but a condition happening when interacting
with the screenedges, which warp the pointer.

This change introduces a PositionUpdateBlocker in
PointerInputRedirection::processMotion to ensure that a processMotion
call finishes prior to the next update. If the PositionUpdateBlocker is
blocked the new position gets scheduled and processed once the
PositionUpdateBlocker gets destroyed.

With this we get the expected sequence for B warping pointer:
   A (1) -> B (1) -> C (1) -> A (2) -> B (2) -> C (2)

This should hopefully improve the interaction with screen edges on
Wayland.

CCBUG: 374867

Test Plan:
Added an auto test demonstrating the issue of incorrect
ordering caused by screenedges. Prior to the change the test is failing.

f0dc01b352 [wayland] Ensure that pointer enter event carries the correct coordinates
So far KWin's pointer surface enter handling was:
1. update fouced surface
2. update the global position

On client side this resulted in:
1. Enter with incorrect coordinates
2. move event to correct coordinate

With QtWayland this results in the case of multiple surfaces in one
application that Qt doesn't properly process the enter event and the
Window never getting pointer focus and not reacting on any pointer
input events.

The root problem is that the KWayland server API is not ideal for
supporting this situation. There is an API call for setting the global
position (which causes a pointer motion for the focused surface) and
an API call to update the focused surface. But a combination for both
is (still) missing.

This change addresses the problem by first unsetting the entered surface,
then updating the global position and afterwards setting the new surface.
Thus the position is correct. While this needs to be made better in
KWayland, this is an urgency bug fix to get the behavior correct and thus
first working around the API deficit and not first extending in KWayland.

513878e20d [autotest/integration] Introduce a Test helper library to have less code duplication
Summary:
A new namespace KWin::Test is added which provides a few helper
functions. It makes it easy to setup a KWayland client connection with
the base set to be able to create a Surface and flags to create
additional interfaces. This replaces the KWayland connection dance in
init() methods. For cleanup() there is also a dedicated helper function.

In addition there are helper functions to:
* render a surface
* create a surface
* create a shell surface
* flush the wayland client connection
* access to the created interfaces - for compatibility with existing code

The idea is to extend this Test library also for other common use cases
like creating an X11 connection and X11 windows, etc.
