while here, enable introspection option by default.

Cogl 1.15.10 2013-09-02
• List of changes since Cogl 1.15.8
» Added API to set the onscreen template on a CoglDisplay outside of
the constructor.
» Added public API to configure the layout of displays when using
the KMS winsys.
» Added a cogl_point_coord builtin variable for snippets which can
be used to render point sprites in more dynamic ways.
» cogl_texture_new_with_size now returns NULL on failure. This
behaviour was accidentally changed in 1.14.0.
» Fixed a problem with setting the precision specifiers on GLES2
which was causing a lot of problems with the latest Mesa.
» Added a “webgl” driver to manage the differences in GLES2 when
compiling with emscripten.
» Fixed a bug with paths which was causing Clutter's texture-fbo
test to crash.
» Some issues with introspecting the cogl-pango API were fixed.
» Added an example using point sprites.
» Build fixes for building with MinGW32.
» Updates to the MSVC build files.
» Documentation fixes to the snippets API.

Cogl 1.15.8 2013-08-20
• List of changes since Cogl 1.15.6
Brown bag release to fix a problem with including cogl-path.h from
cogl.h that meant only code defining
COGL_ENABLE_EXPERIMENTAL_2_0_API would get access to the CoglPath
API.
We now ignore whether COGL_ENABLE_EXPERIMENTAL_2_0_API is defined so
clutter which does define it will see the api and so will clutter
users that don't define it.
Cogl 1.15.6 2013-08-19
• List of changes since Cogl 1.15.4
» Fixed runtime selection of egl-kms backend
» Split out the CoglPath api in-line with cogl master to reduce
divergence, but updated to not break the 1.x API/ABI
» Reverted the semantic change to cogl_offscreen_new_to_texture to
make it synchronously allocate as it did in cogl-1.14. A
replacement cogl_offscreen_new_with_texture api has been
introduced to support the asynchronous allocation behaviour
required to allow configuration of a framebuffer before
allocation.
» Fixed a problem with binding attribute locations with desktop GL
drivers, required to work with the latest Mesa.
» Some configure.ac documentation fixes
» In cogl-gst we make sure to only emit the "pipeline-ready" signal
once the new textures have actually been uploaded.
» Various MSVC build fixes
Note: we took some care to try and avoid breaking the ABI and
chaning the soname relative to the last 1.15.4 snapshot.

Cogl 1.15.4 2013-07-30
• List of changes since Cogl 1.15.2
» Added experimental API to directly expose atlas textures.
» Added new_from_file/data/bitmap APIs for sliced textures.
» Added new_from_file APIs for 2D textures.
» Added cogl_primitive_draw as a new name for the
cogl_framebuffer_draw_primitive function.
» Removed the attribute drawing APIs. Instead applications should
create a primitive and draw that.
» Fixed bug where Cogl would busy-wait with 100% CPU if the Wayland
compositor is closed.
» The COGL_FRAME_EVENT_SYNC events are now sent based on the frame
callback with the Wayland backend.
» New cogl_gst_video_sink_is_ready() function to determine whether a
Cogl-GST video sink is ready to have the pipeline queried.
» Fixed a potential bug with the blending enabled state when copying
a pipeline.
» Fixed detecting the Mesa vendor when GL 3 is used.
» Fixed a reference leak on the CoglRenderer.
» Fixes to the Visual Studio build files.

Cogl 1.15.2 2013-07-09
• List of changes since Cogl 1.14.0
» Lots of Wayland backend work, including updated compositor support
» Updated cogland, a simple example wayland compositor using Cogl
» Made the onscreen resize callback work the same as the frame callback
» New cogl_onscreen_swap_buffers_with_damage api
» New fence API
» New Emscripten support (only basic at the moment)
» Improved blend state tracking
» New cogl_onscreen_add_dirty_callback() api for window systems
that need to notify application of dirty/damaged regions that must
be redrawn by the application
» Started adding internal unit tests to complement the conformance
tests
» New support for per-vertex point sizes
» New cogl-gst sub-library added enabling gstreamer integration into
Cogl based applications. Notably the design is compatible with
applications adding custom shader snippets to a CoglPipeline that
handles video sampling so application will be able to chain
together shader based affects without requiring intermediate
renderers.
» Adds HSL color conversion apis
» The Conformance test suite can now be installed with a .test file
enabling them to be run by the gnome-desktop-testing-runner for example.
• Bugzilla bugs closed since 1.14.0:
#691752 - add fence/sync API

Cogl is a small open source library for using 3D graphics hardware for
rendering. The API departs from the flat state machine style of OpenGL and is
designed to make it easy to write orthogonal components that can render without
stepping on each others toes.
As well as aiming for a nice API, we think having a single library as opposed
to an API specification like OpenGL has a few advantages too; like being
able to paper over the inconsistencies/bugs of different OpenGL
implementations in a centralized place, not to mention the myriad of OpenGL
extensions. It also means we are in a better position to provide utility
APIs that help software developers since they only need to be implemented
once and there is no risk of inconsistency between implementations.
Having other backends, besides OpenGL, such as drm, Gallium or D3D are
options we are interested in for the future.
