Previously cogl_set_fog would cause a flush of the Cogl journal and
would directly bang the GL state machine to setup fogging. As part of
the ongoing effort to track most state in CoglMaterial to support
renderlists this now adds an indirection so that cogl_set_fog now just
updates ctx->legacy_fog_state. The fogging state then gets enabled as a
legacy override similar to how the old depth testing API is handled.
This is a blind patch because I don't know enough about the osx backend
and the osx backend probably doesn't even work these days anyway but
since people have filed bugs specifically on OSX that imply they don't
have a depth or stencil buffer this tries to fix that.
Maybe someone will eventually pick up the osx backend again and verify
if this helps.

Since we'll want to share the fallback logic with CoglVertexArray this
moves the malloc based fallback (for when OpenGL doesn't support vertex
or pixel buffer objects) into cogl-buffer.c.
Explicitly warn if we detect that a CoglBuffer is being freed while it
is still mapped. Previously we silently unmapped the buffer, but it's
not something we want to encourage.
This makes CoglBuffer track the last used bind target as a private
property. This is later used when binding a buffer to map instead of
always using the PIXEL_UNPACK target.
This also adds some additional sanity checks that code doesn't try to
nest binds to the same target or bind a buffer to multiple targets at
the same time.
Normally the asynchronous nature of X means that setting the clutter
stage size may really happen an indefinite amount of time later but
since the tests are so short lived and may only render a single frame
this is not an acceptable semantic.
This way we should be able to remove all the hacky sleeps and frame
count delays from our tests.
Since we now run every test in a separate process there is no need to
try and avoid state leakage between tests. This removes the code to
cleanup all children of the stage and disconnect handlers from the
stage paint signal. We now explicitly print a warning if the users tries
to run multiple tests in one process.
This adds three new feature flags COGL_FEATURE_TEXTURE_NPOT_BASIC,
COGL_FEATURE_TEXTURE_NPOT_MIPMAP and COGL_FEATURE_TEXTURE_NPOT_REPEAT
that can tell you if your hardware supports non power of two textures,
npot textures + mipmaps and npot textures + wrap modes other than
CLAMP_TO_EDGE.
The pre-existing COGL_FEATURE_TEXTURE_NPOT feature implies all of the
above.
By default GLES 2 core supports npot textures but mipmaps and repeat
modes can only be used with power of two textures. This patch also makes
GLES check for the GL_OES_texture_npot extension to determine if mipmaps
and repeating are supported with npot textures.
I had changed the build so CSS files get put into
the HTML build directory; but done it in such
a way that they were then being ignored during
install. Fixed this.
There was a note about constants for keys and
where they are defined in Clutter header files; but
the sentence about where key modifiers are defined
was outside the note. Logically, they belong
together.
In some cases, there were blocks of text which
were really asides/interrupts to the flow, but
which weren't explicitly marked as such. I fixed
them by turning them into <note> blocks.
Made usage of docbook elements consistent across
recipes; to ensure the conventions are kept by others,
added a section about how to write and style recipes.
glDisableVertexAttribArray was defined to glEnableVertexAttribArray so
it would probably cause crashes if it was ever used. Presumably
nothing is using these yet because the generic attributes are not yet
tied to shader attributes in a predictable way.
We now always aim to use pkg-config based configuration when possible,
but when not configure.ac now knows the difference between GLES_CM
libraries that contain EGL symbols (I.e. a separate EGL library doesn't
need to be found) and GLESv1_CM libraries that don't contain EGL
symbols.

In the .json file used for the test, there is no null -> "base"
transition defined only a "clicked" -> "base", when the "clicked" state
is removed the "base" state will also disappear.
I was fed up to cd into the tests/conform or tests/interactive directories
to launch a specific test. Now, with the power the abs_ variants of
builddir and srcdir we can run specific test from any directory.

For testing purposes, either to identify bugs in Cogl or the driver or
simulate lack of PBO support COGL_DEBUG=disable-pbos can be used to
fallback to malloc instead.
The pango renderer was causing lots of override materials to be allocated
because the vertex_buffer API converts AUTOMATIC mode into REPEAT for
backwards compatibility. By explicitly setting the wrap mode to
CLAMP_TO_EDGE when creating the glyph_material then the vertex_buffer
API will leave it untouched.
This allows you to tell Cogl that you are planning to replace all the
buffer's data once it is mapped with cogl_buffer_map. This means if the
buffer is currently being accessed by the GPU then the driver doesn't
have to stall and wait for it to finish before it can access it from the
CPU and can instead potentially allocate a new buffer with undefined
data and map that.
There was a missing '* 4' and '* i' in the for() loops that initialized
the first test buffer, so it was containing uninitialized data causing
the test to fail.
Make Cally follow the single-include header file policy of Clutter and
Cogl; this means making cally.h the single include header, and requires
a new cally-main.h file for the functions defined by cally.h.
Also:
• clean up the licensing notice and remove the FSF address;
• document the object structures (instance and class);
• G_GNUC_CONST-ify the get_type() functions;
• reduce the padding for CallyActor sub-classes;
• reduce the amount of headers included.
Initialize the accessibility support calling cally_accessibility_init
Take into account that this is required to at least be sure that
CallyUtil class is available.
It also modifies cally_accessibility_module_init in order to return
if the initialization was fine (and the name, removing the module word).
It also removes the gnome accessibility hooks, as it is not anymore
module code.
Solves CB#2098
This commit includes a method to init the a11y support. Two main purposes:
* Register the different Atk factories.
* Ensure that there are a AtkUtil implementation class available.
Part of CB#2097
The Clutter Accessibility Library is an implementation of the ATK,
the Accessibility Toolkit, which exposes Clutter actors to accessibility
tools. This allows not only writing accessible user interfaces, but also
allows testing and verification frameworks based on A11Y technologies to
inspect and test a Clutter scene graph.

Since CoglPixelBuffer was renamed to CoglPixelArray the test entry point
was also renamed to test_cogl_pixel_array, but mistakenly the
corresponding test-conform-main.c change wasn't pushed at the same time.
This changes the cogl_is_XYZ function prototypes generated when using
the COGL_OBJECT_DEFINE macro to take a void * argument instead of a
CoglHandle argument.
This removes cogl_pixel_array_new which just took a size in bytes.
Without the image size and pixel format then the driver often doesn't
have enough information to allocate optimal GPU memory that can be
textured from directly. This is because GPUs often have ways to
spatially alter the layout of a texture to improve cache access patterns
which may require special alignment and padding dependant in the images
width, height and bpp.
Although currently we are limited by OpenGL because it doesn't let us
pass on the width and height when allocating a PBO, the hope is that we
can define a better extension at some point.
The usage hint should be implied by the CoglBuffer subclass type so the
public getter and setter APIs for manually changing the usage hint of a
CoglBuffer have now been removed.
Instead of having to extend cogl_is_buffer with new buffer types
manually this now adds a new COGL_BUFFER_DEFINE macro to be used instead
of COGL_OBJECT_DEFINE for CoglBuffer subclasses. This macro will
automatically register the new type with ctx->buffer_types which will
iterated by cogl_is_buffer. This is the same coding pattern used for
CoglTexture.
