The check for the version number was checking against the 2.0.0 micro
version number which isn't expected to change for a long time so the
test was useless.
The README file is generated by the configure script so that it can
include the required dependency version numbers. However there was no
corresponding AC_SUBST calls for the versions so the README would be
left with @THESE_MARKERS@.
The release template had the wrong version number and download URL and
the subject was slightly different from what we used in the previous
release. Also the parts split out from the README were including the
-- separator. These have been removed using tail -n +1. The
documentation section is updated to match the message used for the
1.7.0 release. There is now a note about the release being a
development snapshot that only gets added depending on
COGL_RELEASE_STATUS.
The function declarations for the GL_OES_EGL_image extension were
using the wrong name for the GLeglImageOES type so it was getting
build errors when compiling for GLES.
This adds a cogl-win32-renderer.h for the win32 specific cogl-renderer
API instead of having #ifdef guards in cogl-renderer.h

we've got into a bit of a mess with how we name platform specific
symbols and files, so this is a first pass at trying to tidy that up.
All platform specific symbols should be named like
cogl_<platform>_symbol_name and similarly files should be named like
cogl-<platform>-filename.c
This patch tackles the X11 specific renderer/display APIs as a start.

This adds Xlib and Win32 typesafe replacements for
cogl_renderer_handle_native_event, cogl_renderer_add_native_filter,
cogl_renderer_remove_native_filter. The old functions are kept as an
implementation detail so we can share code.

It used to be that we passed around NULL terminated arrays of
attributes, but since 3c1e83c7f we now explicitly pass an n_attributes
count instead. There were some leftovers of the old approach in the
cogl_vdraw_[indexed]_attributes functions and also there was an
off-by-one error with the n_attributes values passed on which was
causing crashes.

When setting a NULL texture on a CoglPipeline we would also reset the
texture target to a dummy value of 0. Reseting the target also had the
effect of making fragends discard any associated program. In cases where
the NULL texture was only transient until a replacement texture could be
set we were re-running lots of redundant codegen and shader
compilations.

There is a documented rule that layer changes should only be notified to
the fragend once; either as a pipeline change or as a layer change. When
the number of layers associated with a material changes then that should
get notified against the pipeline. All other layer changes get notified
against the layer.
There was a mistake in the _cogl_pipeline_add/remove_layer_difference
functions, in that we weren't using the 'inc/dec_n_layers' boolean to
determine if the fragend should be notified of the change.
It was also noticed that the logic of _cogl_pipeline_prune_to_n_layers
would also break this rule, by failing to notify some changes at all.

This adds API to let you override the choice of Cogl's winsys backend.
Previously it was only possible to override the winsys using the
COGL_RENDERER environment variable, but it's useful for something like
Clutter to be able to control the winsys via API without needing
environment variable tricks. This also adds API to query back the
winsys chosen by Cogl, in case you don't set an explicit override.

This exposes experimental cogl_framebuffer APIs for getting and setting
a viewport without having to refer to the implicit CoglContext. It adds
the following experimental API:
cogl_framebuffer_set_viewport
cogl_framebuffer_get_viewport4fv
cogl_framebuffer_get_viewport_x
cogl_framebuffer_get_viewport_y
cogl_framebuffer_get_viewport_width
cogl_framebuffer_get_viewport_height

This adds a _cogl_init function for Cogl that we expect to be the first
thing called before anything else is done with Cogl. It's not a public
API so it's expected that all entry points for Cogl that might be the
first function used should call _cogl_init().
We currently call _cogl_init() in these functions:
cogl_renderer_new
cogl_display_new
cogl_context_new
cogl_android_set_native_window
_cogl_init() can be called multiple times, and only the first call has
any affect.
For example _cogl_init() gives us a place check and parse the COGL_DEBUG
environment variable.
Since we don't have any need to parse command line arguments (we can
always get user configuration options from the environment) our init
function doesn't require argc/argv pointers.
By saying up front that we aren't interested in command line arguments
that means we can avoid the mess that is GOption based library
initialization which is extremely fragile due to its lack of dependency
tracking between modules.

The recommended command to check for differences from master to the
remote master was using git log with a range from the local master to
the remote master but this wouldn't work if the local master is ahead
of the remote master because the range is backwards. This patch
changes it to recommend git diff --stat instead because then the
command would work even if the two branches have diverged.
The "default" m4 conflicts with one of libtool's internal symbols, one
that is used to determine whether the -fPIC argument should be used;
this breaks compilation onf 64bit platforms.

So that our released tarballs can contain filenames longer than 99
characters we tell automake to create tarballs using the ustar format.
This is newer than the default v7 format but still old enough to be
considered widely portable.
Since gtk-doc is an optional dependency for Cogl then we need to special
case how EXTRA_DIST is initialized. It shouldn't be set when using
gtk-doc since gtk-doc.make expects to initialize EXTRA_DIST. If we
aren't using gtk-doc then it should be initialized to an empty value
instead of including gtk-doc.make so that the later lines that append
various extra png files to EXTRA_DIST won't fail.
This adds a --enable-profile option which enables uprof based profiling.
It was also necessary to fixup a CLUTTER_ENABLE_PROFILING #ifdef in
cogl-context.c to renamed COGL_ENABLE_PROFILING instead. By default Cogl
doesn't output uprof reports directly, instead it assumes a higher level
toolkit will output a report. If you want a report from Cogl you can
export COGL_PROFILE_OUTPUT_REPORT=1 before running your app.
The latest version of uprof can be fetched from:
git://github.com/rib/UProf.git
This update the x11-foreign test so that it checks for events on its X
display and forwards them on to Cogl. It will now also quit if any key
of button is pressed.
This explicitly renames the cogl-2.0 reference manual to
cogl-2.0-experimental and renames the cogl-2.0 pkg-config file to
cogl-2.0-experimental.pc. Hopefully this should avoid
miss-understandings.
The x11-foreign example directly uses the X11 API at it seems that more
recent versions of binutils complain if we don't directly link the test
with libX11 as opposed to relying on indirect linkage via cogl.
This reverts commit 3d2564df8f.
Since 01e1260aa the 'near' and 'far' defines are now undef'd on
Windows so we no longer have to remember not to use them in Cogl code.
This adds an extra header that gets included from config.h where we
can add configuration defines. This is used to #undef 'near' and 'far'
when building for Windows so that we don't have to avoid using them as
variable names in the Cogl code.
This allows to track the number of objects allocated by Cogl. The
results are displayed on the standard output by calling :
cogl_debug_print_instances ();
