e15bc37225 compositor: map overlay window before redirecting windows
When windows get redirected off screen, all that gets left behind
is black. We don't want to flicker black at startup, though.

This commit maps the overlay window early, before redirecting
toplevels, so they end up getting snapshotted onto the background
pixmap of the overlay window when the overlay window is mapped.

6e02fb80c4 Always send _NET_WM_FRAME_DRAWN for newly created windows
Send a _NET_WM_FRAME_DRAWN for each newly created window, as required
by the specification. This avoids a race where a window might be created
frozen but already unfrozen by the time we first see fetch the
counter value.

Remove a duplicate call to meta_compositor_set_updates_frozen() which
was called before the MetaWindowActor is created and hence did nothing.

6e831c88a6 compositor: fix background vignette for non-stretched styles
The background vignette currently fits itself to the painted
texture, instead of the monitor.  This causes some very
wrong looking drawing for backgrounds that don't fill the screen.

This commit reworks the vignette shader code to be clearer, more
correct, and parameterized so that it knows how to scale and
position the vignette.

0e3d164117 compositor: when tiling background, center on screen
The WALLPAPER style of background painting currently
draws starting in the upper left corner of each monitor.

This isn't really correct, it means the seam between
monitors doesn't match up and edges look unbalanced if
the tile isn't a multipe of monitor size.

Really, the tiles should be centered in the middle of
the screen.  (Just like when tiling a bathroom floor,
tiles should start in the center of the room.)

This commit reworks the math to make that happen.

436d3ff8a9 compositor: Make sure we always call the post_paint handlers
Commit 4f2bb583bf started to use a clutter_threads_add_repaint_func_full
callback instead of connecting to the stage's paint signal.

The callback has to return TRUE if it wants to be called again, so fix that
as we want to call it for every frame (otherwise apps supporting the WM SYNC
protocol will stop drawing).

e623406c99 background: Fix gradient color rendering
There is currently code to try to fill gradients in a
hardware native format, using #ifdefs. That optimization is
unimportant since gradients only use 2 byte buffers. It's

580feb0c85 compositor: rework how backgrounds are managed
Background handling in GNOME is very roundabout at the moment.

gnome-settings-daemon uses gnome-desktop to read the background from
disk into a screen-sized pixmap. It then sets the XID of that pixmap
on the _XROOTPMAP_ID root window property.

mutter puts that pixmap into a texture/actor which gnome-shell then
uses.

Having the gnome-settings-daemon detour from disk to screen means we
can't easily let the compositor handle transition effects when
switching backgrounds. Also, having the background actor be
per-screen instead of per-monitor means we may have oversized
textures in certain multihead setups.

This commit changes mutter to read backgrounds from disk itself, and
it changes backgrounds to be per-monitor.

This way background handling/compositing is left to the compositor.

491c5b622e window-actor: Set every window actor to be reactive
Now that the background actor is reactive, this means that
clicks on the window group part of the stage, even when they're
on an X window, will be registered as the background actor, as
all of the other children of the group aren't reactive. This can
happen when a plugin takes a modal grab, for instance.

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.

5876f2e3e5 Fix corner cases where _NET_WM_FRAME_DRAWN might be missed
The WM spec requires _NET_WM_FRAME_DRAWN to *always* be sent when
there is an appropriate update to the sync counter value. We were
potentially missing _NET_WM_FRAME_DRAWN when an application did a
spontaneous update during an interactive resize and during effects.
Refactor the code to always send _NET_WM_FRAME_DRAWN, even when
a window is frozen.

87fe9685b5 Distinguish "no delay" frames from spontaneous drawing
When a client is drawing as hard as possible (without sleeping
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

the "presentation time" of the frame as an offset from the timestamp
in _NET_WM_FRAME_DRAWN.

To provide maximum space in the messages,_NET_WM_FRAME_DRAWN and
_NET_WM_FRAME_TIMINGS are not done as WM_PROTOCOLS messages but

d8696c17be Use clutter_stage_set_sync_delay()
Using a "sync delay" where we wait for 2 ms after the vblank before
starting to draw the next frame provides for much more predictable
latency for applications. An application can know that if it completes
a frame any time between 8ms before the vblank to the vblank,
it will reliably be drawn on the following vblank period, rather than
having an unpredictable latency depending on whether the compositor
is currently busy drawing a frame or not.

04ef448927 Handle _NET_WM_SYNC_REQUEST_COUNTER updates without redraw
It's possible that a client might update the (extended)
_NET_WM_SYNC_REQUEST_COUNTER counter twice without actually drawing
anything. In that case, we still should send a _NET_WM_FRAME_DRAWN

no damage is generated. For now, do it the easy way by forcing a

Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve

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.

424fc5245a Add compositor hook to process keybindings selectively
Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents
to determine the KeyBindingAction the event would have triggered and
run our own handlers (ugh).
Instead, provide a hook to allow the compositor to filter out keybindings
before processing them normally, regardless of whether the compositor
holds a grab or not.

bc96a14185 window-group: Subtract the unredirected window in stage space
meta_window_group_paint tries to carefully figure out which parts of the
scene it can avoid painting. One area it avoids painting is the region of
the screen occupied by an unredirected window (if there's one present).
When subtracting from the visible region, it gets the coordinate spaces
confused, and ends up subtracting the area at the wrong offset. Fix this
by translating the rectangle subtracted from the visible region.

162213be0d Fix cogl crash from updating non-existent texture
The code here was always incorrect - we were processing damage events for

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.

fccd626604 Use a utility function to create GL_ARB_texture_rectangles
meta-texture-rectangle and meta-shaped-texture both create textures
with GL_TEXTURE_RECTANGLE_ARB as the target using direct GL
calls. This patch moves that code into a shared utility function in a
separate file instead. The function resolves the required GL symbols
dynamically instead of linking to them directly so that if Clutter
eventually stops linking to -lGL mutter will continue to build. The
function also splits the texture creation into a separate texture
creation and data upload stage so that it can use
cogl_texture_set_region to upload the data. That way it can avoid
clobbering the glPixelStore state and it can let Cogl do any necessary
format conversion. The code preserves the old value of the rectangle
texture binding instead of clobbering it because Cogl expects to be
able to cache this value to avoid redundant glBindTexture
calls. Finally, the function uses cogl_object_set_data to
automatically destroy the GL texture when the Cogl texture is
destroyed. This avoids having to have special code to destroy the cogl
texture.

texture as a simple way of drawing a solid color without adding a

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

the terminal from the shadow we draw.

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
meta_frames_get_frame_bounds() from it.

Instead, set the opacity on the MetaShadedTexture child and use
it when drawing the shadow.

Since the check MetaWindowGroup does on meta_actor_get_paint_opacity()

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/.

future, more functionality like setting the background from a file or doing
cross-fades can be added.

The new background actor is exposed to plugins via meta_plugin_get_background_actor()
similar to other exposed actors to allow cloning the background for use in
other displays. The actual class is not installed for public consumption at
the moment since it has no useful methods.

bac668d287 Optimize out restacks that don't change actor order
For various reasons (mostly the stack tracker correctly predicting the

that the compositor does to get the actor stacking order) the compositor
can be told to sync the stack when it has nothing to do. Detect this
at the last moment before actually telling Clutter to restack to avoid

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.

c9ebc0ea25 Always use mipmap emulation
Rather than trying to find out from Clutter whether mipmap generation
can be used together with texture_from_pixmap, just always assume
it can't and use the MutterTextureTower emulation code.

This fixes a problem with our previous hack for doing the query
no longer working. In the rare cases where mipmap generation
is supported, it is unlikely to produce significantly more efficient
or better looking results than the emulation. (In terms of efficiency,
we have better knowledge of when we need to update the lower mipmaps
and when we don't than CoglTexturePixmapX11.)

Some care is taken so mutter_shaped_texture_set_create_mipmaps() works
when changed on the fly and properly discards the old mipmap levels.
This isn't necesary currently, since it can only be controlled via
envvar, but is easier than future-proofing through documentation.

91d82bf8c7 mutter-window: request DamageReportBoundingBox report level
In commit d34ae764769 I switched mutter-window to ask for Raw rectangles
from the X server. This avoided 2 non synchronous and 2 synchronous X
requests per window with damage, per frame; 2 (non-sync) to
create/destroy a temporary region to copy the damage region into, 1 to
request the server to copy the damage region into a our given region and
another to fetch that region back into the client. The problem with raw
events though is that it's possible to DOS the compositor with them.

Instead of receiving an event for every bit of damage this patch instead
asks the server to only report BoundingBox changes to the damage region.

0c14640352 mutter-window: stream raw updates to ClutterX11TexturePixmap
This changes the way we handle Damage events so instead of getting an
event when the damage region of a pixmap becomes non-empty we now get
sent all damage rectangles and stream those all though to
ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area()

For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to
clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT
calls are now deferred until just before painting) and since
ClutterGLXTexturePixmap is now capable of queueing clipped redraws that
can result in only updating a sub-region of the stage during a repaint
cycle (and using glXCopySubBufferMESA to present the sub-region redraw
to the front buffer) this should improve performance and reduced power
consumption for a range of use cases. (For example viewing a website
that has animated adverts doesn't force the whole screen to be redrawn
for each frame of the advert)

Besides being able to take advantage of glXCopySubBuffer to only update
a small region of the stage the fact that this patch makes Mutter now
request RawRectangles from the X server means we no longer do a
synchronous X request for a complete Damage Region for every window
damaged each frame. This should also improve performance.

CLUTTER_PAINT=redraws can be used to visualize what parts of the stage
are redrawn and with this patch applied I can open a terminal and as I
type I see that only the damaged areas of the terminal are being
redrawn.

b77b0a3d81 Load one copy of plugins early
Although multi-screen support has not been tested and probably
doesn't fully work, the basic setup for multi-screen is that
we have the same list of plugins for all screens, but a different
instance of the plugins for each screen.

To allow plugins to do setup that is screen independent and needs
to occur early in the setup process, we identify a "default plugin
manager" and load (but not start) that plugin manager's plugins
immediately after we know our list of plugins.

That plugin manager is then reused for the first screen we open
and the plugins are started at that time. Separate plugin managers
are loaded and started for any other screens we open.

(A plugin could keep track of whether the screen-independent
setup has been done in a static variable, or it could do everything
in a way that is safe to do repeatedly.)

Rather than using the plugin objects constructed() method for doing

early before the bulk of Metacity setup, which then allows plugins
to affect how the setup happens. (For example, to change the way
that preferences are loaded.)

This is an incompatible change, since 'screen' is now not set in the
constructed method, so the plugin API version is bumped.
