We are setting mime data with a destroy notify on the cairo
surface to get notified when cairo registers damage for the
surface (in that case, it clears the mime data, calling the
destroy notify). Unfortunately, the destroy notify is also
called when we remove the mime data ourselves, which was
not intentional.
Use a flag in the window impl struct to ignore the callback
when we are clearing the hook.
Keep track of the exact size of X windows in underlying pixels; we
generally use the scaled size instead, but to properly handle the GL
viewport for windows that aren't a multiple of window_scale,
we need to know the real size.

Plug windows weren't redrawing properly because the embedded
window was expecting to get messages for each frame from the
compositor, but the compositor doesn't know about embedded
windows. Simply disable frame sync for GtkPlug's GdkWindow -
extending XEMBED to handle frame sync isn't interesting
at this point.
A new API gdk_x11_window_set_frame_sync_enabled() is added
to allow this to be done.
https://bugzilla.gnome.org/show_bug.cgi?id=701613
If you set GDK_SCALE=2 in the environment then all windows will be
scaled by 2. Its not an ideal solution as it doesn't handle
multi-monitors at different scales, and only affects gtk apps.
But it is a good starting points and will help a lot on HiDPI
laptops.
Instead of making the frame clock a settable property of a window, make
toplevel windows inherently have a frame clock when created (getting
rid of the default frame clock.) We need to create or destroy frame
clocks when reparenting a window to be a toplevel, or to not be a
toplevel, but otherwise the frame clock for a window is immutable.
Deprecate gdk_window_enable_synchronized_configure() and
gdk_window_configure_done() and make them no-ops. Implement the
handling of _NET_WM_SYNC_REQUEST in terms of the frame cycle -
we know that all processing will be finished in the next frame
cycle after the ConfigureNotify is received.
For an operation like synchronizing audio to video playback, we need to
be able to predict the time that a frame will be presented. The details
of this depend on the windowing system, so make the backend predict
a presentation time for ::begin-frame and set it on the GdkFrameTimings.
The timing algorithm of GdkFrameClockIdle is adjusted to give predictable
presentation times for frames that are not throttled by the windowing
system.
Helper functions:
gdk_frame_clock_get_current_frame_timings()
gdk_frame_clock_get_refresh_info()
are added for operations that would otherwise be needed multiple times
in different locations.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Instead of communicating the start of a frame to the window manager
as soon as we begin a frame, start a frame only when we know we've
actually created damage to the contents of a window.
(This uses cairo_set_mime_data() as a notification mechanism - a
clever suggestion from Uli Schlachter.)
The advantage of this is that we aren't forcing the compositor to
do a frame cycle and send _NET_WM_FRAME_DRAWN - depending on how the
compositor is structured that might either cause it to do extra
work or it might send _NET_WM_FRAME_DRAWN early and upset frame
timing.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
As part of the extended _NET_WM_SYNC_REQUEST_COUNTER protocol,
we get a _NET_WM_FRAME_DRAWN message for each frame we draw. Use this
to synchronize the updates we are doing with the compositing manager's
drawing, and ultimately with with display refresh.
We now set the sync request counters on all windows, including
override-redirect windows, since it is also useful to do synchronized,
atomic updates for such windows.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
By exporting two XSync counters on a toplevel window, we subscribe
to an extended form of the _NET_WM_SYNC_REQUEST_COUNTER protocol,
where the window manager can initiate an atomic frame, as previously,
but the application can also do so by incrementing the new counter to
an odd value, and then to an even value to finish the frame.
See:
https://mail.gnome.org/archives/wm-spec-list/2011-October/msg00006.html
The support for 64-bit integers that GLib requires is used to
simplify the logic.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
If the Window Manager supports the _NET_WM_STATE_HIDDEN, we use it to use
the _NET_WM_STATE protocol when de-iconifying windows (iconification is
unchanged, via XIconifyWindow). Additionally, we no longer interpret all
UnmapNotify events for our window as the result of iconification.
(Based on patch by Tomas Frydrych <tf@linux.intel.com>)
_NET_WM_STATE_FOCUSED is a new _NET_WM_STATE hint which allows us to
implement a meaningful GDK_WINDOW_STATE_FOCUSED under X11. If the window
manager doesn't support this hint we keep GDK_WINDOW_STATE_FOCUSED set since
that is what gtk+ implicitly assumed historically.
https://bugzilla.gnome.org/show_bug.cgi?id=661428
No more GdkPixmap to store the icon and its mask, but instead use cairo
surfaces. Also render the icon into the surfaces using Cairo instead of
gdk_pixbuf_render_threshold_alpha().
To avoid drawing the window background of other windows in the area
where the window was we set the bg to none recursively. However, this
is quite costly it the moved window has many siblings. Furthermore, it
is uncommon that siblings overlap, so this cost has little gain.
So, we only set bg None on the parent, which means that there will
be some more flicker in the uncommon case of overlapping siblings.
All the calls that unset private->parent failed if that was
not a native window (impl), instead we need to find the impl window
for the parent. Add some helper functions for this and use them.
For move/resize of child windows, we really need to recursively unset
on the parent, because moving the window could expose other native
children of the parent.
In do_shape_combine_region, only unset background if we're changing
the bounding shape (i.e. not the input shape)
The history before this was kind of twisted as several different
approaches were tested, so that was all squashed into this initial
commit to hide the uninteresting changes and files that were later
removed.
