When adding the frame callback API in 70040166 we decided on a common
idiom for adding callbacks which would return an opaque pointer
representing the closure for the callback. This pointer can then be
used to later remove the callback. The closure can also contain an
optional callback to invoke when the user data parameter is destroyed.
The resize callback didn't work this way and instead had an integer

This adds compiler symbol deprecation declarations for old Cogl APIs so
that users can easily see via compiler warning when they are using these

So that users of Cogl can manage when to show these warnings this

COGL_VERSION_MIN_REQUIRED can be defined to indicate the oldest Cogl api
that the application wants to use. Cogl will only warn about

When a pipeline is added to the cache, a normal copy would previously be
made to use as the key in the hash table. This copy keeps a reference
to the real pipeline which means all of the resources it contains are
retained forever, even if they aren't necessary to generate the hash.
This patch changes it to create a trimmed down copy that only has the
state necessary to generate the hash. A new function called
_cogl_pipeline_deep_copy is added which makes a new pipeline that is
directly a child of the root pipeline. It then copies over the
pertinent state from the original pipeline. The pipeline state is
copied using the existing _cogl_pipeline_copy_differences function.
There was no equivalent function for the layer state so I have added
one.
That way the pipeline key doesn't have the texture data state and it
doesn't hold a reference to the original pipeline so it should be much
cheaper to keep around.

Calculating the hash value for a pipeline can be a bit expensive.
Previously when adding a new pipeline to the hash table we would end
up calculating the hash value once when checking whether the pipeline
is already in the hash table and then again when adding the pipeline
to the hash table. Ideally GHashTable would provide some API to add an
entry with a precalculated hash value to avoid the recalculation, but
seeing as it doesn't do that we can force it to avoid recalculating by
storing the hash value as part of the struct we are using for the key.
That way the hash func passed to GHashTable can simply return the
precalculated value and we can calculate the hash outside of the
GHashTable calls.

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

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

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
