8c1b2d5eda Simplify the frame testing logic in callers to grab borders
A lot of code did something similar to:

  MetaFrameBorders borders;

  if (window->frame)
    meta_frame_calc_borders (window->frame, &borders);
  else
    meta_frame_borders_clear (&borders);

Sometimes, the else part was omitted and we were unknowingly using
uninitalized values for OR windows. Clean this up by just testing
for a NULL frame in meta_frame_calc_borders and clearing for the
caller if so.

5e3d93da87 plugin: Remove unneeded wrapper APIs
Mutter originally started out with the idea that only a subset of the total

d249cfd040 Pass CoglContext to cogl_texture_pixmap_x11_new()
The experimental Cogl api cogl_texture_pixmap_new() was recently changed
so it now expects an explicit CoglContext argument and it can also
return exceptions now via a GError. This patch updates mutters use of
the api accordingly.

c844bab232 meta-background-actor: Chain up in dispose
This was preventing Clutter from running its dispose, preventing
it from being destroyed correctly. While a major bug and possibly
big memory leak, the most obvious effect was the message that Clutter
spat out:

  Clutter-CRITICAL **: clutter_actor_iter_next: assertion `ri->age == ri->root->priv->age' failed

Since we never disposed the actor correctly, it was never removed
from its parent, and the age wasn't updated correctly.

7319b10d72 MetaShapedTexture: Remove visible_pixels_region
When we were shaping the window with a cairo region, there was an easy
optimization to restrict painting only to the pixels we were going to
actually draw. With rounded corners, the amount of work we have to do
figure out what pixels isn't worth the small savings of not drawing the
completely transparent parts of the corners, so remove this optimization,
and the supporting meta_shaped_texture_get_visible_pixels_region()

3e0ef03fd9 MetaShapedTexture: Make public and directly derive from ClutterActor
ClutterTexture has many features that we simply don't use and don't make
sense for a subclass with custom drawing. Deriving directly from ClutterActor
simplifies our code by avoiding workarounds and makes things more robust.

Additionally, make it public. GNOME Shell was already assuming that any
MetaShapedTexture was also a ClutterTexture, and we need to replace these
bits with new API for GNOME Shell to use.

ac7ec585c8 compositor: Use raw Xlib to resize the compositor window
If we get two configure events on the root window in close
sequence, then we could get the sequence:

 ConfigureNotify on the root window w1xh1
   Processed by Mutter
 clutter_actor_set_size(stage, w1, h1)
 <relayout happens, stage window resized by clutter>

 ConfigureNotify on the root window, w2xh2
   Processed by Mutter
 clutter_actor_set_size(stage, w2, h2)
 ConfigureNotify on the stage window, w1, h1)
   Processed by Clutter
 clutter_actor_set_size(stage, w1, h1)
 <relayout happens, stage window resized by clutter>

Leaving the stage at the wrong size. To avoid fighting with Clutter,
switch to resizing the stage with XResizeWindow(), similar to how a
toplevel window is handled by a window manager.

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.

46415bb248 MetaWindowActor: Fix incorrect short-circuit
The code here was wrong in every way: it only updated the shape if all the
borders changed. It never saved new last_borders even if it *had* changed,
and the bounding rectangle's x and y positions were still important otherwise.

This had user-visible impact when doing simple things like changing the
border_width. It would short-circuit here and due to the above incorrectness,
weirdness could happen where windows would be cut off and so on.

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

small inefficiency from this approach became an enormous inefficiency

67c3c93b8f Only shadow ARGB windows with a frame outside the frame
An ARGB window with a frame is likely something like a transparent
terminal. It looks awful (and breaks transparency) to draw a big
opaque black shadow under the window, so clip out the region under
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.

Using MetaWindowActor.opacity for _NET_WM_WINDOW_OPACITY makes 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()
no longer covers this, we need to handle the opacity in
meta_window_actor_get_obscured_region() explicitly.

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/.

bb50f65532 Allow mutter to be used as a library
Move all of the mutter code into a new libmutter-wm.so, split its
main() method into meta_get_option_context(), meta_init() and
meta_run(), add methods for using in-process plugins, and add
libmutter-wm.pc pointing to the new library.

The mutter binary is now just a tiny program that links against
libmutter-wm. The --version and --mutter-plugins options are handled
at the mutter level, not in libmutter-wm, and a few strange unused
command-line options (--no-force-fullscreen and --no-tab-popup) have
been removed.

f2158218be plugins: Add early_initialize vfunc
For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files.  But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.

This requires a plugin API version bump.

Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.

1133a4ff9c Make plugin loading failure fatal
If a plugin was explicitly specified, falling back to the default
silently is bad; a manager component like gnome-session can
do a better job of handling this scenario.

An example we've hit in gnome-shell is where SpiderMonkey changes
without gjs being rebuilt, and loading the plugin fails due to
unresolved symbols.

But there are obviously others, like the file being missing or
corrupt.

If we have repeats on for a full-sized image, then if the background
is displayed scaled (for example, in a desktop preview mode) then we
can get artifacts along the edge of the background where the repeat
of the opposite edge is blended in by bilinear scaling. So turn off
repeats when the screen and background image sizes match.

07e6c5aac2 Draw the root window background
Add code to track and draw the root window background. The advantage of doing
it here as compared to in a plugin is that we can use the visiblity smarts
of MetaWindowGroup to optimize out drawing the background when obscured.

If handling other than tracking the _XROOTPMAP_ID property is desired in the
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
stacking order before getting events, but also because of the processing
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
triggering unnecessary redraws.

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.

Instead of setting shadow parameters on individual windows, add the
idea of a "shadow class". Windows have default shadow classes based

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.
