When we use if (GDK_PROFILER_IS_RUNNING) this means we get an
inlined if (FALSE) when the compiler support is not compiled in, which
gets rid of all the related code completely.
We also expand to G_UNLIKELY(gdk_profiler_is_running ()) in the supported
case which might cause somewhat better code generation.
usec is the scale of the monotonic timer which is where we get almost
all the times from. The only actual source of nsec is the opengl
GPU time (but who knows what the actual resulution of that is).
Changing this to usec allows us to get rid of " * 1000" in a *lot* of
places all over the codebase, which are ugly and confusing.
1. Rename the thing
2. Turn it from a signal to a vfunc
3. Pass the GtkCssStyleChange to it
We don't export any public API about the GtkCssStyleChange yet, it's
just a boring opaque struct.
According to the ICCCM spec [1], one should subtract the base size from
the window size before checking that the aspect ratio falls in range.
This change fixes shrinking Firefox Picture-in-Picture windows when
running KDE Plasma (with KWin as the window manager).

When a new popup surface is created, it may end up
getting a resume-events signal from its frame clock
without having seen a flush-events first.
Don't unpause events in that case, since it messes
up the displays pause counter.
This was causing criticals with tooltips.
The "iconified" state is mostly an X11-ism; every other platform calls
this state "minimized" because it may not involve turning a window into
an icon at all.
Windows/surface's aren't supposed to be explicitly moved by any external
part, so don't provide API for doing so. Usage throughout Gdk is
replaced by the corresponding backend variants.
The generic layer still does the heavy lifting, leaving the backends
more or less just act as thin wrappers, dealing a bit with global
coordinate transformations. The end goal is to remove explicit surface
moving from the generic gdk layer.
To separate how toplevels and popups are configured, a first step is to
introduce a resize-only vfunc for backends to implement. It's meant to
only configure toplevel windows, i.e. popups. Currently it's used for
both types, but introducing the resize-only API is a first step.
Instead of the toplevel driving popups, have the popups listen to the
frame clock themselves. Otherwise, if the toplevel for some reason isn't
drawn by the compositor and stops drawing new frames, popups wouldn't
get painted either.
To make a frame clock tick as long as any of the associated surfaces
expect to receive ticks, make the surfaces inhibit freezing the clock,
instead of directly tell the frame clock to freeze itself.
This makes it so that as long as any surface using a certain frame clock
is not frozen (e.g. just received a frame event from the display
server), the frame clock will not be frozen.
With this, the frame clock is initiated as frozen, and won't be thawed
until any surface inhibits freeze. It will be frozen again, when every
surface has that previously inhibited freeze uninhibited freeze.
This gives us marks to track the duration of processing certain types of
GdkEvent. It also provides some basic struct information in cases where
having that information would likely be useful for debugging.
This function returns the position relative to
the surface parent, so will always return 0 for
non-popups. The out arguments don't need to
allow-none either - nobody passes NULL for these.
We maintain offsets for popups, so we can translate
coordinates between surfaces that are attached directly
or indirectly to the same toplevel. Add an api for that.
There is no need for popups to connect to the frame
clock to pause and unpause events on the display -
the toplevel already does it.
And don't connect to paint either - handle paint
on popups recursively.
Since we are now sharing frame clocks with multiple
surfaces, we can no longer dispose them unconditionally
when a surface goes away. Only do it if we are a
toplevel (without parent).
This was showing up as criticals on exit when opening
and closing any popover in widget factory.
This api is meant to mimic xdg-popover.grab - we
show the surface, and dismiss it when we get events
on other surfaces. For foreign surfaces, the compositor
handles that for us; for our own, we check outselves
before delivering events to GTK.
We don't need the complicated wrapper system anymore,
since client-side windows are gone. This commit moves
all the vfuncs to GtkSurfaceClass, and changes the
backends to just derive their surface implementation
from GdkSurface.
We want to use a gdk_surface_new_popup for popups,
and align the constructor names with the surface
types, so rename
gdk_surface_new_popup -> gdk_surface_new_temp
gdk_surface_new_popup_full -> gdk_surface_new_popup
The temp surface type will disappear eventually.
All the information in it is already contained
in the surface object we pass along, and none
of the backend implementations were using the
attributes at all.
