Clutter uses checks on various environment variables and installs
various command line switches. The API reference should list them
and document them both.
The environment variable to disable mipmapping should also be
a command line switch, and be handled like the rest of Clutter's
environment variables/command line switches.
Clutter is able to show debug messages written using the CLUTTER_NOTE()
macro at runtime, either by using an environment variable:
CLUTTER_DEBUG=...
or by using a command line switch:
--clutter-debug=...
--clutter-no-debug=...
Both are parsed during the initialization process by using the
GOption API.
COGL would benefit from having the same support.
In order to do this, we need a cogl_get_option_group() function in
COGL that sets up a GOptionGroup for COGL and adds a pre-parse hook
that will check the COGL_DEBUG environment variable. The OptionGroup
will also install two command line switches:
--cogl-debug
--cogl-no-debug
With the same semantics of the Clutter ones.
During Clutter initialization, the COGL option group will be attached
to the GOptionContext used to parse the command line options passed
to a Clutter application.
Every debug message written using:
COGL_NOTE (SECTION, "message format", arguments);
Will then be printed only if SECTION was enabled at runtime.
This whole machinery, like the equivalent one in Clutter, depends on
a compile time switch, COGL_ENABLE_DEBUG, which is enabled at the same
time as CLUTTER_ENABLE_DEBUG. Having two different symbols allows
greater granularity.
The ClutterFixed type and symbols are now equivalent to the native
float type. In order to remove ambiguity and clean up the code, any
usage of ClutterFixed and relative macros has been removed.

Mipmapped text is enabled by default in Clutter but it can cause
problems on some drivers so it is convenient to have an environment
variable to disable it for all apps.

Bug #1457 - Creating a new texture messes up the cogl material state
cache; reported by Neil Roberts
We still don't have caching of bound texture state so we always have to
re-bind the texture when flushing the GL state of any material layers.

Bug #1460 - Handling of flags in cogl_material_set_color
Cogl automatically enables/disables blending based on whether the source color
has an alhpa < 1.0, or if any textures with an alpha component are in use, but
it wasn't doing it quite right.
At the same time I removed some of the dirty flags which on second thought
are nothing more than micro-optimsations that only helped clutter the code.

Since the CoglMatrix type was added for supporting texture matrices recently
it made sense to be consistent accross the Cogl API and use the Cogl type
over the GL style GLfloat m[16] arrays.

That was a misunderstanding on my part, and makes it impossible

The INCLUDES directive should only contain pre-processor flags, since
we're passing it also to the introspection scanner.
Using AM_CFLAGS for compiler flags, like debug flags and maintainer
flags, is more indicated.

Bug 1442 - multistage, same-window resize events invalidate stage
When ensuring that the GL context is attached to the correct
ClutterStage we need to set the SYNC_MATRICES flag on the stage
itself. This is needed in case the size of the new stage does
not match the size of the old -- thus requiring a call to
glViewport() when the paint cycle starts.
cogl_wrap_glActiveTexture needs to call the GL version of
glActiveTexture otherwise the subsequent calls to glBindTexture will
all be using texture unit 0. This fixes test-cogl-multitexture.

Previously the texture unit settings were stored in growable GArrays
and every time a new texture unit was encountered it would expand the
arrays. However the array wasn't copied when stored in a
CoglGles2WrapperSettings struct so all settings had the same
array. This meant that it wouldn't detect that a different program is
needed if a texture unit is disabled or enabled.
The texture unit settings arrays are all now a fixed size and the
enabledness of each unit is stored in a bit mask. Therefore the
settings can just be copied around by assignment as before.
This puts a limit on the number of texture units accessible by Cogl
but I think it is worth it to make the code simpler and more
efficient. The material API already poses a limit on the number of
texture units it can use.

configure.ac: Check for gobject-introspection
build/introspection.m4: Include the file that defines the
GOBJECT_CHECK_INTROSPECTION m4 macro in case we want to disable
the introspection data generation.
clutter/json/Makefile.am: Build the .gir for "ClutterJson"
(json-glib as part of the Clutter library)
clutter/Makefile.am: Build the .gir for clutter, compile the
Clutter and ClutterJson girs into typelibs, and install them.
Also move GCC_FLAGS from $(INCLUDES) to $(AM_CFLAGS) since it includes
non-preprocessor flag like -Wall.

Add annotations such as (transfer-none) (out) (element-type ClutterActor),
and so forth to the doc comments as appropriate.
The annotations added here are a combination of the annotations previously
in gir-repository for Clutter and annotations found in a review of all
return values with that were being parsed with a transfer of "full".

The new stable release of gtk-doc provides the --name-space
option for the mkdb utility. This option allows to specify a
namespace for the symbols that will get stripped, so that we
don't get a symbols index containing only "C".
Bug 1464 - clutter_timeline_list_markers should set n_markers=0 when
there are no markers
If no markers are registered and we bail out we should also set the
n_markers out parameter to 0 so that code checking the number of
markers will still work.
Bug 1465 - clutter_path_parse_description should check p==NULL
When accepting a stringified path description, ClutterPath methods
and the parser should not accept NULL or empty strings.
Bug 1463 - clutter_color_lighten(darken) unexpected because of
ClutterFixed=>float
These two functions contained ClutterFixed constants represented as
integers which are no longer valid since the cogl-float branch
merge. They are now converted to ClutterFixed from float constants
using CLUTTER_FLOAT_TO_FIXED (which is now a no-op).

The ChangeLog should only be generated by dist-hook and as a temporary
file to avoid overwriting the stub we use to direct people to the
commit log when cloning the repository.
When generated, the ChangeLog should be copied inside the distdir so
that the autotools will not freak out.
