169ce1508b x11-texture-pixmap: Move signal handler override
The signal handling override for the ::queue-damage-redraw should be
done in the class initialization function, not in the instance one.

c0d5af5de5 Adds initial clipped redraw support to Clutter
A new (internal only currently) API, _clutter_actor_queue_clipped_redraw
can be used to queue a redraw along with a clip rectangle in actor
coordinates. This clip rectangle propagates up to the stage and clutter
backend which may optionally use the information to optimize stage
redraws. The GLX backend in particular may scissor the next redraw to
the clip rectangle and use GLX_MESA_copy_sub_buffer to present the stage
subregion.

The intention is that any actors that can naturally determine the bounds
of updates should queue clipped redraws to reduce the cost of updating
small regions of the screen.

Notes:
» If GLX_MESA_copy_sub_buffer isn't available then the GLX backend
  ignores any clip rectangles.

» queuing multiple clipped redraws will result in the bounding box of
  each clip rectangle being used.

» If a clipped redraw has a height > 300 pixels then it's promoted into
  a full stage redraw, so that the GPU doesn't end up blocking too long
  waiting for the vsync to reach the optimal position to avoid tearing.

  » Note: no empirical data was used to come up with this threshold so
    we may need to tune this.

» Currently only ClutterX11TexturePixmap makes use of this new API. This
  is done via a new "queue-damage-redraw" signal that is emitted when
  the pixmap is updated. The default handler queues a clipped redraw
  with the assumption that the pixmap is being painted as a rectangle
  covering the actors transformed allocation. If you subclass
  ClutterX11TexturePixmap and change how it's painted you now also
  need to override the signal handler and queue your own redraw.

  Technically this is a semantic break, but it's assumed that no one
  is currently doing this.

This still leaves a few unsolved issues with regards to optimizing sub
stage redraws that need to be addressed in further work so this can only
be considered a stepping stone a this point:

» Because we have no reliable way to determine if the painting of any
  given actor is being modified any optimizations implemented using
  _clutter_actor_queue_redraw_with_clip must be overridable by a
  subclass, and technically must be opt-in for existing classes to avoid
  a change in semantics. E.g. consider that a user connects to the paint
  signal for ClutterTexture and paints a circle instead of a rectangle.
  In this case any original logic to queue clipped redraws would be
  incorrect.

» Currently only the implementation of an actor has enough information
  with which to queue clipped redraws. E.g. It is not possible for
  generic code in clutter-actor.c to queue a clipped redraw when hiding
  an actor because actors have no way to report a "paint box". (remember
  actors can draw outside their allocation and actors with depth may
  also be projected outside of their allocation)

  » The current plan is to add a actor_class->get_paint_cuboid()
    virtual so actors can report a bounding cube for everything they
    would draw in their current state and use that to queue clipped
    redraws against the stage by projecting the paint cube into stage
    coordinates.

» Our heuristics for promoting clipped redraws into full redraws to
  avoid blocking the GPU while we wait for the vsync need improving:

  » vsync issues aren't relevant for redirected/composited applications
    so they should use different heuristics. In this case we instead
    need to trade off the cost of blitting when using glXCopySubBuffer
    vs promoting to a full redraw and flipping instead.

79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

894fe4ba93 Always create the Damage object for ClutterX11TexturePixmap auto updates
If clutter_x11_texture_set_window() was called after
clutter_x11_texture_pixmap_set_automatic(), then the Damage object would
not be properly created so updates to the window were ignored.

Refactor creation of the damage object to a separate function, and
call it from clutter_x11_texture_set_window() and clutter_x11_texture_set_pixmap()
as appropriate. Addition and removal of the filter function is made
conditional on priv->damage to make free_damage_resources() cleanly
idempotent.

See: http://bugzilla.gnome.org/show_bug.cgi?id=587189 for the original
bug report.

795e005566 Fix handling of not-visible texture pixmaps
If we have an not-visible texture pixmap, we need to:

 - Still update it if it is realized, since it won't be
   updated when shown. And it might be also be cloned.

 - Queue a redraw if even if not visible, since it
   it might be cloned.

d28c9e5db1 Remove unnecessary setting of CLUTTER_ACTOR_REALIZED flag
An implementaton of realize() never needs to set the
CLUTTER_ACTOR_REALIZED flag, though it can unset the flag if
things fail unexpectedly. (Previously, stage backend implementations
had to do this since clutter_actor_realize() wasn't used; this
is no longer the case.)

1d2ac51ea3 [x11-texture-pixmap] Fixes a reported lockup due to an undesireable X server grab
A lockup was reported by fargoilas on #clutter and removing the server grab in
clutter_x11_texture_pixmap_sync_window fixed the problem.

We were doing an x server grab to guarantee that if the XGetWindowAttributes
request reported that our redirected window was viewable then we would also
be able to get a valid pixmap name.  (the composite protocol says it's an
error to request a name for a window if it's not viewable) Without the grab
there would be a race condition.

Instead we now handle error conditions gracefully.

b716d32000 Fix properties that have X11 types to be 'long'
While X11 Pixmap and Window types only have 32-bits of data, they
are actually 'unsigned long'. Change the "window" and "pixmap"
property of ClutterX11TexturePixmaps to be ulong.

This fixes 64-bit bugs where ClutterGLXTexturePixmap passed a
reference to Pixmap to g_object_get("pixmap", &pixmap, ...);
