a131b697d9 Add the layer's sampler and uniform declarations at the start
Previously the sampler uniform declarations such as cogl_sampler0 were
generated by walking the list of layers in the shader state. This had
two problems. Firstly it would only generate the declarations for
layers that have been referenced. If a layer has a combine mode of
replace then the samplers from previous layers couldn't be used by
custom snippets. Secondly it meant that the samplers couldn't be
referenced by functions in the declarations sections because the
samplers are declared too late.

This patch fixes it to generate the layer declarations in the backend
start function using all of the layers on the pipeline instead. In
addition it adds the sampler declarations to the vertex shader as they
were previously missing.

956d39ac30 Add fragment and vertex snippet hooks for global declarations
This adds hook points to add global function and variable declarations
to either the fragment or vertex shader. The declarations can then be
used by subsequent snippets. Only the ‘declarations’ string of the
snippet is used and the code is directly put in the global scope near
the top of the shader.

The reason this is necessary rather than just adding a normal snippet
with the declarations is that for the other hooks Cogl assumes that
the snippets are independent of each other. That means if a snippet
has a replace string then it will assume that it doesn't even need to
generate the code for earlier hooks which means the global
declarations would be lost.

fc86d0e12e win32: Minor build fixes for building for win32
This fixes some minor errors and warnings that were preventing Cogl
building with mingw32:

• cogl-framebuffer-gl.c was not including cogl-texture-private.h.
  Presumably something else ends up including that when building for
  GLX.

• The WGL winsys was not including cogl-error-private.h

• A call to strsplit in the WGL winsys was wrong.

• For some reason the test-wrap-rectangle-textures test was trying to
  include the GDKPixbuf header.

29983a7e2c buffer: Don't set the invalidate hint when requesting read access
glMapBufferRange is documented to fail with GL_INVALID_OPERATION if
GL_MAP_INVALIDATE_BUFFER_BIT is set as well as GL_MAP_READ_BIT. I
guess this makes sense when only read access is requested because
there would be no point in reading back uninitialised data. However,
Clutter requests read/write access with the discard hint when
rendering to a CoglBitmap with Cairo. The data is new so the discard
hint makes sense but it also needs read access so that it can read
back the data it just wrote for blending.

This patch works around the GL restriction by skipping the discard
hints if read access is requested. If the buffer discard hint is set
along with read access it will recreate the buffer store as an
alternative way to discard the buffer as it does in the case where the
GL_ARB_map_buffer_range extension is not supported.

f79e78f648 Don't #ifdef the call to glDiscardFramebuffer
When Cogl is compiled with support for both the GL and GLES drivers it
only includes the GL header and not the GLES header. That means in
that case it would not compile in the code for the
GL_EXT_discard_framebuffer extension even though it could be used on
the GLES driver. This patch makes it use the standard names for the
GL_COLOR, GL_STENCIL etc names instead of the _EXT suffixed names and
manually defines them if we are using the GLES headers. That way the
discard code can be used unconditionally.

cogl-pipeline-opengl.c was being cleared with the size of a pointer
instead of the size actually allocated for the array. Presumably this

Also the size of the array was slightly wrong because it was allocating
the size of a pointer for each layer instead of the size of an
unsigned long.

queued, it still makes sense to give the winsys a chance to add file
descriptors to the list. The winsys might be relying on the list of
CoglPollFDs passed to poll_dispatch to decide whether to read from a
file descriptor and that should happen even if Cogl also woke up the
main loop because the event queue isn't empty.

b34034217a Make it possible to call swap_buffers within a frame event callback
It seems like it would be quite a reasonable design for an application
to immediately paint the buffer and call swap_buffers within the
handler for the sync event. This previously wouldn't work.

When using the GLX winsys if swap_region is called then it immediately
tries to set the pending notification flag. However if this is called
from the event callback then when the callback is complete it will
clear the flag again and the pending notification will be lost. This
patch just makes it clear the pending flag before invoking the
callback so that it can be safely queued again.

With any winsys that doesn't directly handle the sync event
notification it would almost work except that it was iterating the
live list of pending events. If the callback causes another event to
be added to this list by issuing a buffer swap then the iteration
would never complete and cogl_poll_dispatch would never return. This
patch just makes it steal the list before iterating so that any
additions will be dispatched by a later call to cogl_poll_dispatch
instead.

4efd82a3b6 Convert the two SDL examples to use the frame callback
The two SDL examples now throttle their rendering to the
COGL_FRAME_EVENT_SYNC event. Previously the examples would redraw
whenever a mouse motion event is received but now they additionally
wait for the sync event which means that if another mouse event comes
immediately after rendering the last frame it theoretically could
avoid blocking waiting for the last frame to complete. In practice
however the SDL winsys doesn't support swap events so it will get the
sync event immediately anyway, but it's nice to have the code as an
example and a test.

This patch also changes the mainloop a bit to do the equivalent steps
without the outer main loop which I think makes it a bit easier to
follow.

24733abf68 onscreen: Add CoglFrameInfo and _add_frame_callback() api
Add a CoglFrameInfo object that tracks timing information for frames
that are drawn. We track a frame counter and frame timing information
for each CoglOnscreen. Internally a CoglFrameInfo is automatically
created for each frame, delimited by cogl_onscreen_swap_buffers() or
cogl_onscreen_swap_region() calls.

CoglFrameInfos are delivered to applications via frame event callbacks
that can be registered with a new cogl_onscreen_add_frame_callback()
api. Two initial event types (dispatched on all platforms) have been
defined; a _SYNC event used for throttling the frame rate of
applications and a _COMPLETE event used so signify the end of a frame.

Note: This new _add_frame_callback() api makes the
cogl_onscreen_add_swap_complete_callback() api redundant and so it
should be considered deprecated. Since the _add_swap_complete_callback()
api is still experimental api, we will be looking to quickly migrate
users to the new api so we can remove the old api.

5ce058c0e5 Prefer OML_sync_control over SGI_video_sync when waiting for swap
When we block waiting for the swap, prefer doing that using
glXWaitForMsc() from OML_sync_control because that returns a system
time value for the precise time of the swap.

013548c109 renderer: expose CoglOutputs
This adds a cogl_renderer_foreach_output() function that can be used to
iterate the display outputs for a particular renderer.

This also updates cogl-info to use this new api so it can dump out all
the output information.

88d8bd84f2 Add CoglOutput and track for the GLX backend
The CoglOutput object represents one output such as a monitor or
laptop panel, with information about attributes of the output such as
the position of the output within the global coordinate space, and
the refresh rate.

We don't yet publically export the ability to get output information but
we track it for the GLX backend, where we'll use it to track the refresh
rate.

23eca5c793 Support cogl_renderer_get_n_fragment_texture_units() for ARBfp
There is a cogl_renderer_get_n_fragment_texture_units() function which
is documented to return the number of texture units that are
accessible from a fragment program. This just directly returns the
value from GL_MAX_TEXTURE_IMAGE_UNITS which is available in either the
GLSL extensions or the ARBfp extension. Clutter-GST relies on this to
determine whether it can use a program to convert the YUV data on the
GPU.

When the GL3 driver was added in 66c9db993595b this was changed to
only query the value when the GLSL feature is available. Previously it
would always query the value when the GL or GLES2 driver is used. This
change makes sense on master because there is no API for an
application to make its own ARBfp programs so the only way to access
texture units from a program is via GLSL. However on the 1.14 branch
this patch broke clutter-gst when GLSL is disabled because it thinks
the ARBfp programs can't use multi-texturing.

This patch just changes it to also query the value when ARBfp support
is available.

Note: it's probably note a good idea to apply this patch to master,
but only to the 1.14 branch. On master the function probably needs to
be changed anyway because it is using _COGL_GET_CONTEXT().
