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:

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 ();

When validating a user pipeline before drawing with a CoglVertexBuffer
we sometimes find we have to make some overrides and we handle that by
creating a pipeline which is a weak copy of the user pipeline. The weak
pipeline gets associated with the original pipeline so if that pipeline
is used multiple times then we can re-use the same override pipeline and
skip validation. Because it's a weak pipeline we get notified when the
original material is destroyed or changed so we know our weak pipeline
is now invalid.
When we get notified that the weak material is invalid we should unref
it, but instead we were just discarding our reference to it. This was
resulting in leaking weak materials and in some cases those materials
referenced textures which would then also be leaked.
The wrapper for the can_hardware_repeat had a cut and paste error so
it would call the wrong function on the child texture.
Many thanks to Owen Taylor for finding this bug.
When rendering a box for an unknown glyph it would previously just use
the average glyph size for the font. This causes problems because the
size calculations for the layout assume a different size so it can end
up rendering outside of the expected ink rectangle. This patch changes
it to query the size of the glyph in the font. Pango should end up
reporting the size of what would be the hex box which should be the
same as the sized used for the extents calculation.

The COGL_DEBUG=disable-texturing debug variable disables texturing in
the fixed function fragend by not bothering to enable the texture
targets. This wasn't working for the programmable fragends because the
texture targets don't need to be enabled to use them. This patch
modifies the two programmable backends to generate a constant value
for the texture lookups in the shader when the debug variable is
given.
Instead of using _cogl_xlib_add/remove_filter we now use
_cogl_renderer_add/remove_native_filter. The _cogl_xlib_add_filter API
was only required as a stop gap while EGL support was still in Clutter
because in that case we were using the stub winsys and didn't have a
CoglRenderer.
This removes the redundant _cogl_xlib_trap/untrap_errors functions that
simply wrap equivalent functions in the _cogl_renderer_xlib namespace.
These were originally only required while the EGL winsys was being
handled in clutter and so there wasn't a CoglRenderer in all cases.
This adds an example cogl compositor to test the
_cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4
output displays but doesn't support input since Cogl doesn't deal with
input. It's quite a minimal example of what it takes to write a wayland
compositor so could be interesting to anyone learning about wayland.
In the winsys vtable .xlib_get_visual_info and
.onscreen_x11_get_window_xid should be guarded by the
COGL_HAS_EGL_PLATFORM_POWERVR_X11_SUPPORT because they need to be there
if cogl is configured with --enable-xlib-egl-platform but not if just
configured with --enable-xlib.
When iterating through all the possible window systems trying to find
one we can successfully connect we now associated the current winsys
vtable with the renderer before calling winsys->renderer_connect in case
the implementation calls some other Cogl API that expects to be able to
determine the current winsys. For example calling _cogl_get_proc_address
when querying winsys extensions as part of a successful connect will
need to get at the current winsys vtable.
This adds internal API to be able to wrap a wayland buffer as a
CoglTexture2D. There is a --enable-wayland-egl-server option to decide
if Cogl should support this feature and potentially any EGL based winsys
could support this through the EGL_KHR_image_base and
EGL_WL_bind_display extensions.
By using the EGL_KHR_image_base/pixmap extensions this adds support for
wrapping X11 pixmaps as CoglTexture2D textures. Clutter will
automatically take advantage of this if using the
ClutterX11TexturePixmap actor.
This adds an internal texture_2d constructor that can wrap an EGLImage
as a CoglTexture2D. The plan is to utilize this for texture-from-pixmap
support with EGL as well as creating textures from wayland buffers.
This moves the --enable-cairo check because it was put in the middle of
the logic that handles the --enable-debug option. This moves the
--enable-cairo check down after the --enable-debug logic and adds a
comment header to delimit the option like we have for other options.
Instead of the stub winsys being a special case set of #ifdef'd code
used when COGL_HAS_FULL_WINSYS wasn't defined, the stub winsys now
implements a CoglWinsysVtable like all other winsys backends (it's just
that everything is a NOP). This way we can get rid of the
COGL_HAS_FULL_WINSYS define and also the stub winsys can be runtime
selected whereas before it was incompatible with all other winsys
backends.
Since we no longer have any xlib based backends in Clutter that depend
on the stub winsys in Cogl we can now remove all the special case code
we had for this in cogl-xlib.c
This exposes a CoglTexture2D typedef and adds the following experimental
API:
cogl_is_texture_2d
cogl_texture_2d_new_with_size
cogl_texture_2d_new_from_data
cogl_texture_2d_new_from_foreign
Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.
Note: With these new entrypoints we now expect a CoglContext pointer to
be passed in, instead of assuming there is a default context. The aim is
that for Cogl 2.0 we won't have a default context so this is a step in
that direction.
Until we have a standalone quartz winsys we don't want to define a
winsys name called "quartz" which is what the current --enable-quartz
option does. For now anyone building for OSX needs to use the stub
winsys and setup their own GL context.
This validates that the viewport width and height arguments are positive
values in _cogl_framebuffer_set_viewport. In addition, just before
calling glViewport we also assert that something else hasn't gone amiss
and that the internal viewport width/height values we track are still
positive before passing to glViewport which generates an error for
negative values.
