Erik Kurzinger 9a7484f95c xwayland: correctly report PresentCompleteModeCopy
After executing a PresentPixmap request using the copy path, Xwayland
will clear the vblank's pixmap field and re-queue it for the next msc so
that on the next frame a PresentCompleteNotify event will be delivered
to the client by present_execute_post.

While this does work, since the pixmap field of the vblank will be NULL
when present_execute_post is called, the mode reported in the event will
always be PresentCompleteModeSkip, even if the request *was* actually
executed with a copy.

To fix this, we introduce a new "copy_executed" flag in the
xwl_present_event struct. If xwl_present_execute sees that this flag is
set, it will fall straight through to present_execute_post like it does
if the window or pixmap is NULL. So, after executing a request with
present_execute_copy, instead of clearing the pixmap field we will set
the copy_executed flag to true. This will cause present_execute_post to
report the correct completion mode to the client when the
PresentCompleteNotify event is delivered on the next frame.

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
