f947fe958f cogl-texture-2d: Add an internal wrapper around glCopyTexSubImage2D
This adds a function called _cogl_texture_2d_copy_from_framebuffer
which is a simple wrapper around glCopyTexSubImage2D. It is currently
specific to the texture 2D backend.

5cc062c16c cogl-framebuffer: Add _cogl_blit_framebuffer
This adds the _cogl_blit_framebuffer internal function which is a
wrapper around glBlitFramebuffer. The API is changed from the GL
version of the function to reflect the limitations provided by the
GL_ANGLE_framebuffer_blit extension (eg, no scaling or mirroring).

5a159fcef4 cogl-gles: Check for the GL_ANGLE_framebuffer_blit extension
This extension is the GLES equivalent of the GL_EXT_framebuffer_blit
extension except that it has some extra restrictions. We need to check
for some extension that provides glBlitFramebuffer so that we can
unconditionally use ctx->drv.pf_glBlitFramebuffer in both GL and GLES
code. Even with the restrictions, the extension provides enough
features for what Cogl needs.

80bae51c01 cogl-atlas-texture: Make copying a texture out more robust
Previously when _cogl_atlas_texture_migrate_out_of_atlas is called it
would unreference the atlas texture's sub-texture before calling
_cogl_atlas_copy_rectangle. This would leave the atlas texture in an
inconsistent state during the copy. This doesn't normally matter but
if the copy ends up doing a render then the atlas texture may end up
being referenced. In particular it would cause problems if the texture
is left in a texture unit because then Cogl may try to call
get_gl_texture even though the texture isn't actually being used for
rendering. To fix this the sub texture is now unrefed after the copy
call instead.

e57aa3ca3e cogl-framebuffer: Separate the draw and read buffer
The current framebuffer is now internally separated so that there can
be a different draw and read buffer. This is required to use the
GL_EXT_framebuffer_blit extension. The current draw and read buffers
are stored as a pair in a single stack so that pushing the draw and
read buffer is done simultaneously with the new
_cogl_push_framebuffers internal function. Calling
cogl_pop_framebuffer will restore both the draw and read buffer to the
previous state. The public cogl_push_framebuffer function is layered
on top of the new function so that it just pushes the same buffer for
both drawing and reading.

When flushing the framebuffer state, the cogl_framebuffer_flush_state
function now tackes a pointer to both the draw and the read
buffer. Anywhere that was just flushing the state for the current
framebuffer with _cogl_get_framebuffer now needs to call both
_cogl_get_draw_buffer and _cogl_get_read_buffer.

3d8445807a backend-glx: Remove redundant glFlush()
As noted in commit ce3f55292a an explict glFlush is needed for
both glBlitFramebuffer and glXCopySubBuffer.

_clutter_backend_glx_blit_sub_buffer was already doing an explicit
flush when using glBlitFramebuffer, so just do it unconditonally
and remove the call from clutter_stage_glx_redraw.

a297fb0394 offscreen: Fix partially off-stage actors being clipped in the fbo
If an actor was partially off of the stage, it would be clipped because
of the stage viewport. This produces problems if you use an offscreen
effect that relies on the entire actor being rendered (e.g. shadows).

Expand the viewport in this scenario so that the offscreen-rendering isn't
clipped.

2ee7052d89 cogl-framebuffer: Fix flushing the framebuffer on push
When pushing a framebuffer it would previously push
COGL_INVALID_HANDLE to the top of the framebuffer stack so that when
it later calls cogl_set_framebuffer it will recognise that the
framebuffer is different and replace the top with the new
pointer. This isn't ideal because it breaks the code to flush the
journal because _cogl_framebuffer_flush_journal is called with the
value of the old pointer which is NULL. That function was checking for
a NULL pointer so it wouldn't actually flush. It also would mean that
if you pushed the same framebuffer twice we would end up dirtying
state unnecessarily. To fix this cogl_push_framebuffer now pushes a
reference to the current framebuffer instead.

3afa732bce cogl-framebuffer: Remove all dependencies after a flush

645ca56208 cogl: Set the layer matrix on the right layer instead of a random one
When uploading the layer matrix to GL it wasn't first calling
glActiveTextureMatrix to set the right texture unit for the
layer. This would end up setting the texture matrix on whatever layer
happened to be previously active. This happened to work for
test-cogl-multitexture presumably because it was coincidentally
setting the layer matrix on the last used layer.

ef4688fd0e Avoid direct access to the main context events queue
The GQueue that stores the global events queue is handled all over the
place:

  • the structure is created in _clutter_backend_init_events();
  • the queue is handled in clutter-event.c, clutter-stage.c and
    clutter-backend.c;
  • ClutterStage::dispose cleans up the events associated with
    the stage being destroyed;
  • the queue is destroyed in ClutterBackend::dispose.

Since we need to have access to it in different places we cannot put it
inside ClutterBackendPrivate, hence it should stay in ClutterMainContext;
but we should still manage it from just one place - preferably by the
ClutterEvent API only.

20b1350614 wayland: check for egl extensions explicitly
eglGetProcAddress() returns non-null function pointers
whether or not they're actually supported by the driver,
since it can be used before any driver gets loaded. So
we have to check if the extensions are advertised first,
which requires having an initialized display, so we split
the display creation code into its own function.

The exception to extension-checking is EGL_MESA_drm_display,
since by definition it's needed before any display is even
created.

55e26e23df cogl-vertex-buffer: Use a ref count on the pipeline private data
The pipeline private data is accessed both from the private data set
on a CoglPipeline and the destroy notify function of a weak material
that the vertex buffer creates when it needs to override the wrap
mode. However when a CoglPipeline is destroyed, the CoglObject code
first removes all of the private data set on the object and then the
CoglPipeline code gets invoked to destroy all of the weak children. At
this point the vertex buffer's weak override destroy notify function
will get invoked and try to use the private data which has already
been freed causing a crash.

This patch instead adds a reference count to the pipeline private data
stuct so that we can avoid freeing it until both the private data on
the pipeline has been destroyed and all of the weak materials are
destroyed.

5740a5a38a cogl-pipeline: Fix comparing the color in set_layer_combine_constant
In cogl_pipeline_set_layer_combine_constant it was comparing whether
the new color is the same as the old color using a memcmp on the
constant_color parameter. However the combine constant is stored in
the layer data as an array of four floats but the passed in color is a
CoglColor (which is currently an array of four guint8s). This was
causing valgrind errors and presumably also the check for setting the
same color twice would always fail.

This patch makes it do the conversion to a float array upfront before
the comparison.

2ded18933e cogl-matrix: Get rid of the *_packed variants
cogl_matrix_project_points and cogl_matrix_transform_points had an
optimization for the common case where the stride parameters exactly
match the size of the corresponding structures. The code for both when
generated by gcc with -O2 on x86-64 use two registers to hold the
addresses of the input and output arrays. In the strided version these
pointers are incremented by adding the value of a register and in the
packed version they are incremented by adding an immediate value. I
think the difference in cost here would be negligible and it may even
be faster to add a register.

Also GCC appears to retain the loop counter in a register for the
strided version but in the packed version it can optimize it out and
directly use the input pointer as the counter. I think it would be
possible to reorder the code a bit to explicitly use the input pointer
as the counter if this were a problem.

Getting rid of the packed versions tidies up the code a bit and it
could potentially be faster if the code differences are small and we
get to avoid an extra conditional in cogl_matrix_transform_points.

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.

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.

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.

We have a bunch of experimental convenience functions like

seemed a bit odd to have the vertex annotation e.g. "P2T2" be an infix

CoglVertexP2T2. This switches them all to follow the postfix naming
style.
