634e4ffd1a osx: Improve the event loop
Implementation of event loop which works with GLib events, native OS X
events and Clutter events.

The event loop source code comes from the equivalent code in the Quartz
GDK backend from GTK+ 2.22.1, which is LGPL v2.1+ and thus compatible
with Clutter's licensing terms.

The code has been tested with libsoup, which did not work before together
with Clutter.

9be4cfe8a9 x11/stage: Use a global Window ↔ Stage relationship
Since we need to find the stage from the X11 Window, it's better to use
a static hashmap that gets updated every time the ClutterStageX11:xwin
member is changed, instead of iterating over every stage handled by the
global ClutterStageManager singleton.

82d1e5a6ee Clean up crossing event synthesis code
Clutter should just require that the windowing system used by a backend
adds a device to the stage when the device enters, and removes it from
the stage when the device leaves; with this information, we can
synthesize every crossing event and update the device state without
other intervention from the backend-specific code.

The generation of additional crossing events for actors that are
covering the stage at the coordinates of the crossing event should be
delegated to the event processing code.

The x11 and win32 backends need to be modified to relay the enter and
leave events from the windowing system.

b3784bd2b4 event: Add a setter for the device field
When synthesizing events coming from input devices it should be
possible to just call a setter function, to avoid a huge switch
on the type of the event.

Clutter should also store the device pointer inside the private
data, for faster access of the pointer in allocated events.

Finally, the get_device_id() and get_device_type() accessors should
just be wrappers around clutter_event_get_device(), to reduce the
amount of code duplication.

acf51259d2 x11: Store a back pointer to the backend in the stage
Since we access it in order to get the X11 Display pointer, it makes
sense to have the ClutterBackendX11 already available inside the
ClutterStageX11 structure, and avoid the pattern:

  ClutterBackend *backend = clutter_get_default_backend ();
  ClutterBackendX11 *backend_x11 = CLUTTER_BACKEND_X11 (backend);

which costs us a function call, a type cast and an unused variable.

1d7e223313 test-path: Fix the test when running against latest Cairo versions

behaviour when testing the conversion to and from a Cairo path.

e7519a149b clutter-stage-x11: Don't ensure the viewport when the window moves
When we receive a ConfigureNotify event that doesn't affect the size
of the window (only the position) then we were still calling
clutter_stage_ensure_viewport which ends up queueing a full stage
redraw. This patch makes it so that it only ensures the viewport when
the size changes as it already did for avoiding queueing a relayout.

It now also avoids setting the clipped redraws cool off period when
the window only moves under the assumption that it's only necessary
for size changes.

32486fe995 pipeline: fix for _init_multi_property_sparse_state
When copying COMBINE state in
_cogl_pipeline_layer_init_multi_property_sparse_state we would read some
state from the destination layer (invalid data potentially), then
redundantly set the value back on the destination. This was picked up by
valgrind, and the code is now more careful about how it references the
src layer vs the destination layer.

bca39776d3 framebuffer: flush journal when switching framebuffers
There is currently a problem with per-framebuffer journals in that it's
possible to create a framebuffer from a texture which then gets rendered
too but the framebuffer (and corresponding journal) can be freed before
the texture gets used to draw with.

Conceptually we want to make sure when freeing a framebuffer that - if
it is associated with a texture - we flush the journal as the last thing
before really freeing the framebuffer's meta data. Technically though
this is awkward to implement since the obvious mechanism for us to be
notified about the framebuffer's destruction (by setting some user data
internally with a callback) notifies when the framebuffer has a
ref-count of 0. This means we'd have to be careful what we do with the
framebuffer to consider e.g. recursive destruction; anything that would
set more user data on the framebuffer while it is being destroyed and
ensuring nothing else gets notified of the framebuffer's destruction
before the journal has been flushed.

For simplicity, for now, this patch provides another solution which is
to flush framebuffer journals whenever we switch away from a given
framebuffer via cogl_set_framebuffer or cogl_push/pop_framebuffer. The
disadvantage of this approach is that we can't batch all the geometry of
a scene that involves intermediate renders to offscreen framebufers.
Clutter is doing this more and more with applications that use the
ClutterEffect APIs so this is a shame. Hopefully this will only be a
stop-gap solution while we consider how to reliably support journal
logging across framebuffer changes.

4609770bb9 cogl-clip-stack: Fix flushing multiple stencil rectangles
When flushing a clip stack that contains more than one rectangle which
needs to use the stencil buffer the code takes a different path so
that it can combine the new rectangle with the existing contents of
the stencil buffer. However it was not correctly flushing the
modelview and projection matrices so that rectangle would be in the
wrong place.

6102f80244 test-clip: Replace the ellipse with a rotated rectangle
With test-clip it's possible to draw three different shapes depending
on what mouse button is used: a rectangle, an ellipse or a path
containing multiple shapes. However the ellipse is also a path so it
doesn't really test anything extra from the third option. This
replaces the ellipse with a rectangle that is first rotated by the
modelview matrix. The rotated matrix won't be able to use the scissor
so it can be used to test stencil and clip plane clipping.

35a2d79e46 cogl-debug: Split the flags to support more than 32
The CoglDebugFlags are now stored in an array of unsigned ints rather
than a single variable. The flags are accessed using macros instead of
directly peeking at the cogl_debug_flags variable. The index values
are stored in the enum rather than the actual mask values so that the
enum doesn't need to be more than 32 bits wide. The hope is that the
code to determine the index into the array can be optimized out by the
compiler so it should have exactly the same performance as the old
code.

67fdb5c9f8 cogl-pipeline: Flush the lighting params in common code not vertend
The lighting parameters such as the diffuse and ambient colors were
previously only flushed in the fixed vertend. This meant that if a
vertex shader was used then they would not be set. The lighting
parameters are uniforms which are just as useful in a fragment shader
so it doesn't really make sense to set them in the vertend. They are
now flushed in the common cogl-pipeline-opengl code but the code is
#ifdef'd for GLES2 because they need to be part of the progend in that
case.

e778018d0d cogl-pipeline-progend-glsl: Generalize updating GLES2 uniforms
The uniforms for the alpha test reference value and point size on
GLES2 are updating using similar code. This generalizes the code so
that there is a static array of predefined builtin uniforms which
contains the uniform name, a pointer to a function to get the value
from the pipeline, a pointer to a function to update the uniform and a
flag representing which CoglPipelineState change affects the
uniform. The uniforms are then updated in a loop. This should simplify
adding more builtin uniforms.

9ff04e8a99 cogl-shader-boilerplate: Move the uniforms to the common code
The builtin uniforms are accessible from either the vertex shader or
the fragment shader so we should define them in the common
section. This doesn't really matter for the current list of uniforms
because it's pretty unlikely that you'd want to access the matrices
from the fragment shader, but for other builtins such as the lighting
material properties it makes sense.

e8d5be0ba7 ClutterTimeline: Fix the 'msecs' parameter for the new-frame signal
Between Clutter 0.8 and 1.0, the new-frame signal of ClutterTimeline
changed the second parameter to be an elapsed time in milliseconds
rather than the frame number. However a few places in clutter were
still calling the parameter 'frame_num' which is a bit
misleading. Notably the signature for the signal class closure in the
header was using the wrong name. This changes them to use 'msecs'.

5c0aaf50a7 clutter-timeline: Emit the new-frame signal even on the first frame
ClutterTimeline has special handling for the first time do_tick is
called which was not emitting a new-frame signal. This meant that an
application which directly uses the timeline would have to manually
setup the initial state of an animation after starting a timeline to
avoid painting a single frame with the wrong state. It seems to make
more sense to instead emit the new-frame signal so that the
application always sees a new-frame when the progress changes before a
paint.

Instead of using an idle handler that synchonously paints the stage
by manually calling clutter_actor_paint (stage) the test now uses an

do_events is now called from a "paint" signal handler for the stage, and
instead of manually determining the fps the test now uses
CLUTTER_SHOW_FPS=1 instead.

9a663d8e41 debug: Adds a COGL_DEBUG=disable-fast-read-pixel option
COGL_DEBUG=disable-fast-read-pixel can be used to disable the
optimization for reading a single pixel colour back by looking at the
geometry in the journal and not involving the GPU. With this disabled we
will always flush the journal, rendering to the framebuffer and then use
glReadPixels to get the result.

1bdb0e6e98 cogl: Implements a software only read-pixel fast-path
This adds a transparent optimization to cogl_read_pixels for when a
single pixel is being read back and it happens that all the geometry of
the current frame is still available in the framebuffer's associated
journal.

The intention is to indirectly optimize Clutter's render based picking
mechanism in such a way that the 99% of cases where scenes are comprised
of trivial quad primitives that can easily be intersected we can avoid
the latency of kicking a GPU render and blocking for the result when we
know we can calculate the result manually on the CPU probably faster
than we could even kick a render.

A nice property of this solution is that it maintains all the
flexibility of the render based picking provided by Clutter and it can
gracefully fall back to GPU rendering if actors are drawn using anything
more complex than a quad for their geometry.

It seems worth noting that there is a limitation to the extensibility of
this approach in that it can only optimize picking a against geometry
that passes through Cogl's journal which isn't something Clutter
directly controls.  For now though this really doesn't matter since
basically all apps should end up hitting this fast-path. The current
idea to address this longer term would be a pick2 vfunc for ClutterActor
that can support geometry and render based input regions of actors and
move this optimization up into Clutter instead.

Note: currently we don't have a primitive count threshold to consider
that there could be scenes with enough geometry for us to compensate for
the cost of kicking a render and determine a result more efficiently by
utilizing the GPU. We don't currently expect this to be common though.

Note: in the future it could still be interesting to revive something
like the wip/async-pbo-picking branch to provide an asynchronous
read-pixels based optimization for Clutter picking in cases where more
complex input regions that necessitate rendering are in use or if we do
add a threshold for rendering as mentioned above.

e289e85397 matrix: fix transform/project_points() APIs
Both cogl_matrix_transform_points and _project_points take points_in and
points_out arguments and explicitly allow pointing to the same array
(i.e. to transform in-place) The implementation of the various internal
transform functions though were not handling this possability and so it
was possible the reference partially transformed vertex values as if
they were original input values leading to incorrect results. This patch
ensures we take a temporary copy of the current input point when
transforming.

23ed01d4e9 cogl: Adds _cogl_util_point_in_polygon API
This adds a utility function that can determine if a given point

use this for a software based read-pixel fast path that avoids using the
GPU to rasterize journaled primitives and can instead intersect a point
being read with quads in the journal to determine the correct color.
