Previously the alpha component of the test texture data was always set
to 255 and the data was read back as RGB so that the alpha component
is ignored. Now the alpha component is set to a generated value and
the data is read back a second time as RGBA to verify that Cogl is not
doing any premult conversions when the internal texture and target
data is the same.

The CSS Color Module 3, available at:
http://www.w3.org/TR/css3-color/
allows defining colors as:
rgb ( r, g, b )
rgba ( r, g, b, a)
along with the usual hexadecimal and named notations.
The r, g, and b channels can be:
• integers between 0 and 255
• percentages, between 0% and 100%
The alpha channel, if included using the rgba() modifier, can be a
floating point value between 0.0 and 1.0.
The ClutterColor parser should support this notation.
The Behaviour class and its implementations have been replaced by the
new animation framework API and by the constraints for layout-related
animations.
Currently, we need to make tests build, so we undef DISABLE_DEPRECATED
in specific test cases while they get ported.
When COGL_ENABLE_EXPERIMENTAL_2_0_API is defined cogl.h will now include
cogl2-path.h which changes cogl_path_new() so it can directly return a
CoglPath pointer; it no longer exposes a prototype for
cogl_{get,set}_path and all the remaining cogl_path_ functions now take
an explicit path as their first argument.
The idea is that we want to encourage developers to retain path objects
for as long as possible so they can take advantage of us uploading the
path geometry to the GPU. Currently although it is possible to start a
new path and query the current path, it is not convenient.
The other thing is that we want to get Cogl to the point where nothing
depends on a global, current context variable. This will allow us to one
day define a sensible threading model if/when that is ever desired.
We now prepend a set of defines to any given GLSL shader so that we can
define builtin uniforms/attributes within the "cogl" namespace that we
can use to provide compatibility across a range of the earlier versions
of GLSL.
This updates test-cogl-shader-glsl.c and test-shader.c so they no longer
needs to special case GLES vs GL when splicing together its shaders as
well as the blur, colorize and desaturate effects.
To get a feel for the new, portable uniform/attribute names here are the
defines for OpenGL vertex shaders:
#define cogl_position_in gl_Vertex
#define cogl_color_in gl_Color
#define cogl_tex_coord_in gl_MultiTexCoord0
#define cogl_tex_coord0_in gl_MultiTexCoord0
#define cogl_tex_coord1_in gl_MultiTexCoord1
#define cogl_tex_coord2_in gl_MultiTexCoord2
#define cogl_tex_coord3_in gl_MultiTexCoord3
#define cogl_tex_coord4_in gl_MultiTexCoord4
#define cogl_tex_coord5_in gl_MultiTexCoord5
#define cogl_tex_coord6_in gl_MultiTexCoord6
#define cogl_tex_coord7_in gl_MultiTexCoord7
#define cogl_normal_in gl_Normal
#define cogl_position_out gl_Position
#define cogl_point_size_out gl_PointSize
#define cogl_color_out gl_FrontColor
#define cogl_tex_coord_out gl_TexCoord
#define cogl_modelview_matrix gl_ModelViewMatrix
#define cogl_modelview_projection_matrix gl_ModelViewProjectionMatrix
#define cogl_projection_matrix gl_ProjectionMatrix
#define cogl_texture_matrix gl_TextureMatrix
And for fragment shaders we have:
#define cogl_color_in gl_Color
#define cogl_tex_coord_in gl_TexCoord
#define cogl_color_out gl_FragColor
#define cogl_depth_out gl_FragDepth
#define cogl_front_facing gl_FrontFacing
The size of the texture used for test-cogl-npot-texture was only using
1 pixel of waste and the texture was scaled down so it would be quite
likely that the test would still pass if only the top left slice was
rendered. It also didn't test using non-default texture
coordinates. These problems made it fail to pick up bug 2398. The
texture is now using the maximum amount of waste and rendered in four
parts at 1:1 scale.
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.

Unparented actors are owned by the Script instance, and if that goes
away then the actors go away with it. The fact that we needed an
explicit destroy() before was a hint of a memory management issue that I
blissfully - and regretfully - ignored for the sake of a passing test
suite.
They are generated at configure time, so it's a good idea to have them
in the main ignore file instead of adding them to the built ignore files
under tests.
By using a new signal, ::create-surface (width, height), it should be
possible for third party code and sub-classes to override the default
surface creation code in CairoSurface.
This commit takes a bit of the patch from:
http://bugzilla.clutter-project.org/show_bug.cgi?id=1878
which cleans up CairoTexture; the idea, mutuated from that bug, is that
the CairoTexture actor checks whether the surface it has it's an image
one, and in that case it uses a Cogl texture as the backing store. In
case the surface is not an image one we assume that the surface itself
has some way of updating the GL state and flush the surface.
Re-order the units into a sensible list, with basic tests at the
beginning, and per-class tests at the end - with Cogl last.
Also, start renaming the unit functions from test_<foo> to <foo>,
so that the executable wrappers and the reports have sensible names.
The TODO() macro for adding new tests to the test suite has always meant
to be implemented like the TODO block in Test::More, i.e. a test that is
assumed to fail, and which warns if it unexpectedly succeeds.
Since GTest lacks the expressivity of Test::More, the implementation
just verifies that the tests marked as TODO actually fail, and will fail
if they happen to succeed - at which point the developer will have to
change the macro to SIMPLE or SKIP.
Even if gtester-report doesn't use that information (yet), we should
store the revision of Clutter that generated the report, and the date in
which the test suite was ran.
Instead of trying to run ./test-conformance with the -l option to
generate a list of available tests it now runs sed on the
test-conform-main.c file instead. Running the generated executable is
a pain for cross-compiling so it would be nice to avoid it unless it's
absolutely necessary. Although you could tell people who are cross
compiling to just disable the conformance tests, this seems a shame
because they could still be useful along with the wrappers for example
if the cross compile is built to a shared network folder where the
tests can be run on the actual device.
The sed script is a little more ugly than it could be because it tries
to avoid using the GNU extensions '\+' and '\|'.
The script ends up placing restrictions on the format of the C file
because the tests must all be listed on one line each. There is now a
comment to explain this. Hopefully the trade off is worth it.

As a convenient test that clipped redraws are working correctly in
response to X pixmap damage this updates test-pixmap to have a repeating
1 second timeout that draws arcs on the pixmap.
*** This is an API change ***
The general pattern for axis-aligned arguments is:
x argument
y argument
If we consider columns an x-aligned argument, and row a y-aligned
argument, then we need to update the TableLayout functions to be:
column
row
and not:
row
column
Instead of calling clutter_init immediately, test-conformance now only
calls it as part of test_conform_simple_fixture_setup. The conformance
tests assert that only one test is run per instance of
test-conformance so it should never end up calling clutter_init
twice. Delaying clutter_init has the advantage that calling
"test-conformance -l" will still work even on systems with no X
server. This could be useful for automated build systems.
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.
This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:
- clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
- clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*
The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.
This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.
*** This is an API change ***
Replaced the original drag-threshold property with two separate
horizontal (x-drag-threshold) and vertical (y-drag-threshold)
thresholds.
It is some times necessary to have different drag thresholds for the
horizontal and vertical axes. For example, when a draggable actor is
inside a horizontal scrolling area, only vertical movement must begin
dragging. That can be achieved by setting the x-drag-threshold to
G_MAXUINT while y-drag-threshold is something usual, say, 20 pixels.
This is different than drag axis, because after the threshold
has been cleared by the pointer, the draggable actor can be dragged
along both axes (if allowed by the drag-axis property).

Creating new materials for every Texture instance results in a lot of
ARBfp programs being generated/compiled. Since most textures will just
be similar we should create a template material for all of them, and
then copy it in every instance. Cogl will try to optimize the generation
of the program and, hopefully, will reuse the same program most of the
time.
With this change, a simple test shows that loading 48 textures will
result in just two programs being compiled - with and without batching
enabled.

The tests/accessibility, tests/micro-bench and the examples directory
in the coobook create a lot of non-installed binaries. Since we know who
they are, and we ignore them, we can auto-generate the ignore files as
well.
The rest of Clutter is covered by the main ignore file.
