304005e04f wayland-surface: Replace MetaWindowActor with MetaSurfaceActor
Since subsurfaces won't have toplevel MetaWindowActors, we need to
use MetaSurfaceActor instead. These are embedded in the MetaWindowActor,
just like MetaShapedTexture was (in fact, MetaSurfaceActor now contains

74e43a4702 cullable: Turn cull_out / reset_culling into a separate interface
Instead of hardcoded knowledge of certain classes in MetaWindowGroup,
create a generic interface that all actors can implement to get parts of
their regions culled out during redraw, without needing any special
knowledge of how to handle a specific actor.

The names now are a bit suspect. MetaBackgroundGroup is a simple
MetaCullable that knows how to cull children, and MetaWindowGroup is the
"toplevel" cullable that computes the initial two regions. A future
cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so
that we only have a generic MetaSimpleCullable, and move the "toplevel"
cullability to be a MetaCullableToplevel.

7c45d6594c MetaWindowActor: Use allocation changes signals for size changed signals
When a Wayland compositor, simply rely on the clutter actor allocation
changed signal to sync geometry and emit window actor size changed
signals.

Attaching a wl_buffer to a MetaShapedTexture will signal allocation
changed on the corresponding MetaSurfaceActor, which the MetaWindowActor
is listening to.

ea916b6c49 Introduce MetaSurfaceActor for drawing MetaWindowActor content
Instead of having MetaWindowActor only have one single MetaShapedTexture
as actor drawing its content, introduce a new abstract MetaSurfaceActor
that takes care of drawing.

This is one step in the direction to decouple MetaWaylandSurface with a
MetaWindow and MetaWindowActor (except for shell/xdg surfaces) in order
to finally support subsurfaces like features, or any feature where
window is not drawn using a single texture.

The first step, implemented in this patch, is to not have
MetaWindowActor work directly with a shaped texture. There are still
some cases where it simply gets the texture and goes on as before, but
this should be changed by either removing the need of going via
MetaWindowActor or by adding some generic interface to MetaSurfaceActor
that doesn't limit its functionality to one shaped texture.

There should be no visible difference nor after this patch, but
meta_window_actor_get_texture() and meta_surface_actor_get_texture()
should be deprecated when equivalent functionality has been introduced.

f08921bd0c meta-shaped-texture: Don't queue redraws for obscured regions
When we get a damage event we update the window by calling
meta_shaped_texture_update_area which queues a redraw on the actor.
We can avoid that for obscured regions by comparing the damage area to
our visible area.

where they should be sent; they will be added back in a later commit.

0089b5769c shaped-texture: Turn blending off when drawing entirely opaque regions
When drawing entirely opaque regions, we traditionally kept blending on
simply because it made the code more convenient and obvious to handle.
However, this can cause lots of performance issues on GPUs that aren't
too powerful, as they have to readback the buffer underneath.

Keep track of the opaque region set by windows (through _NET_WM_OPAQUE_REGION,
Wayland opaque_region hints, standard RGB32 frame masks or similar), and draw
those rectangles separately through a different path with blending turned off.

9a5f243f73 wayland: refactor window destruction and focus
The previous code was leaving focus fields dirty in MetaWaylandPointer
and MetaWaylandKeyboard at time (which could crash the X server
because of invalid object IDs)
The new code is more tighly integrated in the normal X11 code
for handling keyboard focus (meaning that the core idea of input
focus is also correct now), so that meta_window_unmanage() can
do the right thing. As a side benefit, clicking on wayland clients
now unfocus X11 clients.
For the mouse focus, we need to clear the surface pointer when
the metawindowactor is destroyed (even if the actual actor is
kept alive for effects), so that a repick finds a different pointer
focus.

268ebb1b18 wayland: Add basic input support
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.

The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.

f9a11b3b18 wayland: Adds basic hybrid X + Wayland support
This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.

This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.

TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.

Note: At this point no input is supported

531be6c413 Track the X Shape input region and use it for picking
We now track whether a window has an input shape specified via the X
Shape extension. Intersecting that with the bounding shape (as required
by the X Shape extension) we use the resulting rectangles to paint
window silhouettes when picking. As well as improving the correctness of
picking this should also be much more efficient because typically when
only picking solid rectangles then the need to actually render and issue
a read_pixels request can be optimized away and instead the picking is
done on the cpu.

c2a9ccb7e2 Let the UI layer (via the core) construct the frame mask
This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".

The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

d900d83522 MetaWindowActor: Go back to freezing affecting actor geometry
We do, in fact, need freezing to affect window geometry, so that
move-resize operations (such as an interactive resize from the
left, or a resize of a popup centered by the application) occur
atomically.

So to make map effects work properly, only exclude the initial
placement of a window from freezing. (In the future, we may want
to consider whether pure moves of a window being done in response
to a user drag should also be excluded from freezing.)

Rename meta_window_sync_actor_position() to
meta_window_sync_actor_geometry() for clarity.

3d337a98d9 MetaWindowActor: Freeze shouldn't affect actor position
If a window is frozen because it is repainting, that shouldn't kee[p
us from updating its position: we don't want a slow-to-update window
to move around the screen chunkily when dragged. (This does reduce
the efficiency of begin/end frames for replacing double-buffering,
but that never works very well in the case where there was an overlapping
window or the entire screen needed redrawing for whatever reason.)

This fixes a bug where a window that was mapped frozen would not get
positioned properly until after the map effect finished, and would
jump from 0,0 at that point. Since effects *do* need to prevent
actor repositioning by Mutter, we must position the actor before any
effect starts.

Because we now are queuing invalidates on frozen windows, fix the
logic for that so that we properly update everything when the window
unfreezes.

between frames) we need to draw as soon possible, since sleeping
will decrease the effective frame rate shown to the user, and
can also result in the system never kicking out of power-saving
mode because it doesn't look fully utilized.

Use the amount the client increments the counter value by when
ending the frame to distinguish these cases:

 - Increment by 1: a no-delay frame
 - Increment by more than 1: a non-urgent frame, handle normally

This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,
possible to glean this information from the bounding shape region of
a client window, but not for an ARGB32 window. This new hint allows
clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

90f2a3ae4c mutter-window-actor: Improve unredirect heuristic
Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve
their performance.

Newer games like fullscreen webgl games and SDL2 using games (like L4D) as well as wine based games do not use override redirect windows so we need a better
heuristic to catch them.

GLX windows always damage the whole window when calling glxSwapBuffers and
never damage sub regions. So we can use that to detect them.

The new heuristic unredirects windows fullscreen windows that have damaged the
whole window more then 100 times in a row.

162213be0d Fix cogl crash from updating non-existent texture
The code here was always incorrect - we were processing damage events for
windows without having a texture. Before, this didn't matter, as
cogl_texture_get_width silently returned 0 for invalid handles. Cogl commit
4c3dadd35e changed this.

The fix here involves two strategies. First, we try to guard MetaTextureTower
from invalid textures. Second, we try not to go down the path that eventually
calls meta_shaped_texture_update_area by not handling damage events if we
don't have a texture for the window.

An ARGB window with a frame is likely something like a transparent

Add meta_window_get_frame_bounds() to get a cairo region for the
outer bounds of the frame of a window, and modify the frame handling
code to notice changes to the frame shape and discard a cached
region. meta_frames_apply_shapes() is refactored so we can extract

349fb7c297 MetaWindowActor: keep a reference to the MetaWindow
Until the actor is destroyed, we need to have access to the
MetaWindow to access some fields used for painting. Keep a strong
reference to the window rather than just hoping the window will
not be freed.

c84da3ce1b Move the installed includes to a subdir
If mutter is going to be a "real" library, then it should install its
includes so that users can do

    #include <meta/display.h>

rather than

    #include <display.h>

So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.

There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.

a9504f1495 MetaWindowActor: Add a 'position-changed' signal
Similar to the recently added 'size-changed' signal, we may want to do
something in response to a window being repositioned without waiting for
notify::allocation. (Especially since what we can do in notify::allocation
is severely limited by Clutter forbidding queueing an allocation at that
point.)

ad707be01e window-actor: Add "size-changed" signal
Emit a signal when the window size changes. While it is already
possible to connect to notify::allocation (or width/height), the
new signal is emitted outside a clutter allocation cycle, which
makes it more convenient when adjusting an actor's size/position
in response.

64c37852b1 meta-actor-window: Use G_UNLIKELY for TFP check
This is just a microptimization, as we pretty much always use
TFP (and do the check every time we set a pixmap),
we can let gcc generate better code here.

8b24711bba Omit shadows for fullscreen and maximized windows
Fullscreen and maximized windows never have visible shadows - the only
case where we would ever see them is if they bleed onto an adjacent
monitor and that looks bad.

It's small performance win to avoid computing them, and this also avoids
painting the top shadow for all maximized windows in GNOME Shell - since
the top panel isn't a X window, it doesn't factor into the computation
of what parts of windows are visible and maximized windows are computed
as having a top shadow.

ca5f2ac3ec Implement more accurate clipping of obscured shadows
Instead of making optimizing obscured shadows an all-or-none operation,
pass the clip region to meta_shadow_paint() and only paint the 9-slices
that are at least partially visible.

1bbaec81ce Make window shadows globally configurable
Instead of setting shadow parameters on individual windows, add the
idea of a "shadow class". Windows have default shadow classes based
on their frame and window type, which can be overriden by setting
the shadow-class property.

Each shadow class has separably configurable parameters for the
focused and unfocused state. New shadow classes can be defined with
arbitrary names.

8eb31944a5 MetaShadowFactory: Add the ability to top-fade a shadow
For attached modal dialogs, we want the shadow to fade out at the top
as if the window was glued to the parent at the top. Add a
shadow-top-fade property to MetaWindowActor and the corresponding
parameter to meta_shadow_factory_get_shadow().

The internal implementation of MetaShadow is adjusted to work
in terms of an "inner border" and "outer border" instead of doing
the calculations in terms of an aggregate border and the spread
of the shadow. The old way of doing things gets clumsy when the
top_fade distance is added in as well.

9f4942e9a7 Make shadows pretty and configurable
The current shadow code just uses a single fixed texture (the Gaussian
blur of a rectangle with a fixed blur radius) for drawing all window
shadows. This patch adds the ability

* Implement efficient blurring of arbitrary regions by approximating
  a Gaussian blur with multiple box blurs.

* Detect when multiple windows can use the same shadow texture by
  converting their shape into a size-invariant MetaWindowShape.

* Add properties shadow-radius, shadow-x-offset, shadow-y-offset,
  shadow-opacity to allow the shadow for a window to be configured.

* Add meta_window_actor_paint() and draw the shadow directly
  from there rather than using a child actor.

* Remove TidyTextureFrame, which is no longer used

b445ee3763 Remove compatibility for GTK+-2.0
While the Meego developers agreed to switching mutter to GTK+-3.0
unconditionally a while ago, Canonical used a GTK+-2.0 build for their
Unity project. As Canonical now announced a switch to compiz as their
window manager, there is no longer a reason to maintain GTK+-2.0
compatibility.
