db6c452aaa pipeline: split out all layer state apis
As part of an on-going effort to get cogl-pipeline.c into a more
maintainable state this splits out all the apis relating just to
layer state. This just leaves code relating to the core CoglPipeline
and CoglPipelineLayer design left in cogl-pipeline.c.

This splits out around 2k more lines from cogl-pipeline.c although we
are still left with nearly 4k lines so we still have some way to go!

9b58b6f472 pipeline: split out all core state apis
Since cogl-pipeline.c has become very unwieldy this make a start at
trying to shape this code back into a manageable state. This patche
moves all the API relating to core pipeline state into
cogl-pipeline-state.c. This doesn't move code relating to layer state
out nor does it move any of the code supporting the core design
of CoglPipeline itself.

This change alone factors out 2k lines of code from cogl-pipeline.c
which is obviously a good start. The next step will be to factor
out the layer state and then probably look at breaking all of this
state code down into state-groups.

c7969a33af cogl: Bind the locale dir for the Cogl domain
dgettext (which Cogl is using) doesn't work unless you first tell
gettext where the locale dir is for the library's domain. This just

f1c2d7e965 2.0: Add cogl2-experimental.h + don't pollute .pc CFLAGS
Instead of adding -DCOGL_ENABLE_EXPERIMENTAL_2_0_API to the
cogl-2.0-experimental.pc file we now install a cogl2-experimental.h
that #defines COGL_ENABLE_EXPERIMENTAL_2_0_API before including
cogl.h.

The problem with having the define in the .pc file is that you might
develop a library that depends on the experimental 2.0 api internally
and then you might want to use that library with Clutter which still
uses the 1.0 API but the .pc file for your library will indirectly,
automatically enable the 2.0 api which can cause conflicts.

2ac4002084 cogl: Add support for reading a cogl.conf config file
When cogl initializes we now check for a cogl/cogl.conf in any of the
system config dirs (determined using $XDG_CONFIG_DIRS on linux) we then
also check the user's config directory (determined using XDG_CONFIG_HOME
on linux) for a cogl/cogl.conf file. Options specified in the user
config file have priority over the system config options.

The config file has an .ini style syntax with a mandatory [global]
section and we currently understand 3 keynames: COGL_DEBUG, COGL_DRIVER
and COGL_RENDERER which have the same semantics as the corresponding
environment variables.

Options set using the environment variables have priority over options
set in the config files. To allow users to undo the enabling of debug
options in config files this patch also adds a check for COGL_NO_DEBUG
environment variable which will disable the specified options which may
have been enabled in config files.

461bff1867 fragend-arbfp: Move the pipeline cache to a separate file
The pipeline cache is now handled in CoglPipelineCache instead of
directly in the ARBfp fragend. The flags needed to hash a pipeline
should be exactly the same for the ARBfp and GLSL fragends so it's
convenient to share the code. The hash table now stores the actual
pipeline as the value instead of the private data so that the two
fragends can attach their data to it. That way it's possible to use
the same pipeline key with ancestors that are using different
fragends.

The hash table is created with g_hash_table_new_full to set a
destructor for the key and value and there is a destructor for
CoglPipelineCache that gets called when the CoglContext is
destroyed. That way we no longer leak the pipelines and shader state
when the context is desroyed.

b2e735ff7f Dynamically load the GL or GLES library
The GL or GLES library is now dynamically loaded by the CoglRenderer
so that it can choose between GL, GLES1 and GLES2 at runtime. The
library is loaded by the renderer because it needs to be done before
calling eglInitialize. There is a new environment variable called
COGL_DRIVER to choose between gl, gles1 or gles2.

The #ifdefs for HAVE_COGL_GL, HAVE_COGL_GLES and HAVE_COGL_GLES2 have
been changed so that they don't assume the ifdefs are mutually
exclusive. They haven't been removed entirely so that it's possible to
compile the GLES backends without the the enums from the GL headers.

When using GLX the winsys additionally dynamically loads libGL because
that also contains the GLX API. It can't be linked in directly because
that would probably conflict with the GLES API if the EGL is
selected. When compiling with EGL support the library links directly
to libEGL because it doesn't contain any GL API so it shouldn't have
any conflicts.

When building for WGL or OSX Cogl still directly links against the GL
API so there is a #define in config.h so that Cogl won't try to dlopen
the library.

Cogl-pango previously had a #ifdef to detect when the GL backend is
used so that it can sneakily pass GL_QUADS to
cogl_vertex_buffer_draw. This is now changed so that it queries the
CoglContext for the backend. However to get this to work Cogl now
needs to export the _cogl_context_get_default symbol and cogl-pango
needs some extra -I flags to so that it can include
cogl-context-private.h

59f746d281 cogl-context: Remove the driver private data
Since the GL function pointers have move to the root of CoglContext,
the driver specific data for GLES became empty and the GL data had
only one varible which apparently nothing was using. It's therefore
convenient to remove the private driver data to make it easier to have
a build of Cogl which enables both GL and GLES support. If we ever
need driver private data later we might want to use
cogl_object_set_user_data instead.

dae02a99a5 Move all of the GL function pointers directly to CoglContext
Instead of storing all of the feature function pointers in the driver
specific data of the CoglContext they are now all stored directly in
CoglContext. There is a single header containing the description of
the functions which gets included by cogl-context.h. There is a single
function in cogl-feature-private.c to check for all of these
functions.

The name of the function pointer variables have been changed from
ctx->drv.pf_glWhatever to just ctx->glWhatever.

The feature flags that get set when an extension is available are now
separated from the table of extensions. This is necessary because
different extensions can mean different things on GLES and GL. For
example, having access to glMapBuffer implies read and write support
on GL but only write support on GLES. The flags are instead set in the
driver specific init function by checking whether the function
pointers were successfully resolved.

_cogl_feature_check has been changed to assume the feature is
supported if any of the listed extensions are available instead of
requiring all of them. This makes it more convenient to specify
alternate names for the extension. Nothing else had previously listed
more than one name for an extension so this shouldn't cause any
problems.

8bfde524f8 matrix: Flatten cogl-matrix-mesa.[ch] into cogl-matrix.[ch]
It has been overly cumbersome to work with the matrix code ever since we
pulled in the mesa code because we initially kept the mesa and the
original cogl code separate. We have made several updates to the mesa
code since integrating, and the coding style has changed a lot compared
to the original mesa code, so there's little point in keeping the two
files separate any longer.

17c9cb8d49 Add the code from FreeBSD for their linked-list/queue implementation
This directly copies in the header from the FreeBSD kernel for their
linked-list implementation. A later patch will modify it but this
patch is here so we can have a clear patch to show what the
changes are.

Using the list implementation from this header is beneficial as
opposed to using GList because it's possible to embed the list
pointers directly into another struct. This saves a separate
allocation and it also makes it possible to remove an item from the
list without having to iterate the entire list to find its list
node. The header provides four different list types: single and
doubley linked lists and each of them can either have a header with
pointers to the beginning and end or just to the beginning. Glib
effectively only provides single and doubley linked lists with a
pointer to the beginning or a doubley-linked list with a pointer to
both (GQueue).

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.

that for Cogl 2.0 we won't have a default context so this is a step in

f436582114 android: Add support for an EGL/Android winsys
The native window type of the EGL/Android winsys is ANativeWinow*. The
Android NDK gives you a pointer to this ANativeWindow and you just need
to configure that window using the EGLConfig you are choosing when
creating the context.

This means you have to know the ANativeWindow* window before creating
the context. This is solved here by just having a global variable you
can set with cogl_android_set_native_window() before creating the
context. This is a bit ugly though, and it conceptually belongs to the
OnScreen creation to know which ANativeWindow* to use. This would need a
"lazy context creation" mechanism, waiting for the user to create the
OnScreen to initialize the GL context.

07c0b9f89f Add CoglDepthState API
Instead of simply extending the cogl_pipeline_ namespace to add api for
controlling the depth testing state we now break the api out. This adds
a CoglDepthState type that can be stack allocated. The members of the
structure are private but we have the following API to setup the state:

    cogl_depth_state_init
    cogl_depth_state_set_test_enabled
    cogl_depth_state_get_test_enabled
    cogl_depth_state_set_test_function
    cogl_depth_state_get_test_function
    cogl_depth_state_set_writing_enabled
    cogl_depth_state_get_writing_enabled
    cogl_depth_state_set_range
    cogl_depth_state_get_range

This removes the following experimental API which is now superseded:

    cogl_material_set_depth_test_enabled
    cogl_material_get_depth_test_enabled
    cogl_material_set_depth_test_function
    cogl_material_get_depth_test_function
    cogl_material_set_depth_writing_enabled
    cogl_material_get_depth_writing_enabled
    cogl_material_set_depth_range
    cogl_material_get_depth_range

Once a CoglDepthState structure is setup it can be set on a pipeline
using cogl_pipeline_set_depth_state().

4a7762d6d7 cogl-context: Store winsys features in an array of unsigned ints
Previously the mask of available winsys features was stored in a
CoglBitmask. That isn't the ideal type to use for this because it is
intended for a growable array of bits so it can allocate extra memory
if there are more than 31 flags set. For the winsys feature flags the
highest used bit is known at compile time so it makes sense to
allocate a fixed array instead. This is conceptually similar to the
CoglDebugFlags which are stored in an array of integers with macros to
test a bit in the array. This moves the macros used for CoglDebugFlags
to cogl-flags.h and makes them more generic so they can be shared with
CoglContext.

1928f7ec0e backend: remove untested fruity backend
This backend hasn't been used for years now and so because it is
untested code and almost certainly doesn't work any more it would be a
burdon to continue trying to maintain it. Considering that we are now
looking at moving OpenGL window system integration code down from
Clutter backends into Cogl that will be easier if we don't have to
consider this backend.

efb570fdae Adds the ability to build Cogl standalone
This adds an autogen.sh, configure.ac and build/autotool files etc under
clutter/cogl and makes some corresponding Makefile.am changes that make
it possible to build and install Cogl as a standalone library.

Some notable things about this are:
A standalone installation of Cogl installs 3 pkg-config files;
cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for
compatibility with what clutter installed though I'm not sure that
anything uses it so maybe we could remove it. cogl-1.0.pc is what
Clutter would use if it were updated to build against a standalone cogl
library. cogl-2.0.pc is what you would use if you were writing a
standalone Cogl application.

A standalone installation results in two libraries currently, libcogl.so
and libcogl-pango.so. Notably we don't include a major number in the
sonames because libcogl supports two major API versions; 1.x as used by
Clutter and the experimental 2.x API for standalone applications.
Parallel installation of later versions e.g. 3.x and beyond will be
supportable either with new sonames or if we can maintain ABI then we'll
continue to share libcogl.so.

The headers are similarly not installed into a directory with a major
version number since the same headers are shared to export the 1.x and
2.x APIs (The only difference is that cogl-2.0.pc ensures that
-DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of
later versions is not precluded though since we can either continue
sharing or later add a major version suffix.

d40cdfa3e1 Moves all GLX code down from Clutter to Cogl
This migrates all the GLX window system code down from the Clutter
backend code into a Cogl winsys. Moving OpenGL window system binding
code down from Clutter into Cogl is the biggest blocker to having Cogl
become a standalone 3D graphics library, so this is an important step in
that direction.
