dd6935f129 stb_image: use glib sized types
Instead of creating typedefs like uint8, uint16 and uint32 we now use
the glib sized typedefs in stb_image to avoid conflict with the uint8,
uint16 and uint32 typedefs on android.

b2964b6910 ext-functions: Don't assume GLchar typedef
We shouldn't assume the GLchar is a valid typedef with all GL headers
when declaring all the symbols in cogl-ext-functions.h to lookup. GLchar
may not be avilable with gles1 for example so we were seeing build

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.

9270412495 cogl-blend-string: Fix TEXTURE_N sources
The parser couldn't cope with TEXTURE_N source arguments because the
sources are checked in turn to find one that matches the beginning of
the argument. The TEXTURE_N source was checked last so it would end up
matching the regular 'TEXTURE' source and then the parser would choke
when it tries to parse the trailing parts.

This patch just moves the check for TEXTURE_ to the top. It also also
changes it so that the argument only needs to be at least 8 characters
long instead of 9. This is necessary because the parser doesn't
consider the digits to be part of the name of the argument so while we
are parsing 'TEXTURE_0' the length is only 8.

d4dc51849e egl: Make sure to free the underlying egl objects when the display is freed
If the display has been setup up, we should destroy the underlying
objects that the winsys has created. This can be done by calling the
winsys->destroy_display() function in _free.

Then, in that function, and for the NULL and GDL EGL platform we can
destroy the surface we have created in the setup_display() function
(through create_context()).

This allows to have clutter create a "dummy" display in
cogl_renderer_check_onscreen_template(), then free it, then recreate the
context and the surface that will be the final ones.

b8b37f6c41 quaternion: fix init_from_array and get_rotation_axis
In cogl_quaternion_init_from_array we were passing the address of the x
component as the destination for memcpy, but that was wrong at least
because w is actually the first member in the structure.  Another
concern raised was whether it was safe to assume that there was no
padding within the CoglQuaternion struct with some compilers so we also
switch to explicitly indexing each element of the array we want to copy.
In practice I think it's pretty safe to assume that padding will only be
introduced to ensure members are naturally aligned, but being explicit
is readable and it can't hurt to be extra cautious.

Another good catch in bug #655228 was that in
cogl_quaternion_get_rotation_axis we had a copy and paste error at the
end where we finally extract the axis and we were repeatedly calculating
just the x component. Now we calculate the y and z components too.

Thanks to Bug #655228 for identifying these issues.

d259a87602 Don't use the 'NULL' GModule to resolve GL symbols
Previously, _cogl_get_proc_address had a fallback to resolve the
symbol using g_module_open(NULL) to get the symbol from anywhere in
the address space. The EGL backend ends up using this on some drivers
because eglGetProcAddress isn't meant to return a pointer for core
functions. This causes problems if something in the process is linking
against a different GL library, for example Cairo may be linking
against libGL itself. In this case it may end up resolving symbols
from the GL library even if GLES is being used.

This patch removes the fallback. The EGL version now has its own
fallback instead which passes the existing libgl_module from the
renderer to g_module_symbol so that it should only get symbols from
that library or its dependency chain. The GLX and WGL winsys only call
glXGetProcAddress and wglGetProcAddress. The stub winsys does however
continue using the global symbol lookup.

The internal _cogl_get_proc_address function has been renamed to
_cogl_renderer_get_proc_address because it needs a connected renderer
to work so it could be considered to be a renderer method. The pointer
to the renderer is passed down to the winsys backends so that it can
use the data attached to the renderer to get the module pointers.

a9184d5cb7 Export API for uploading a tex subregion from a CoglBuffer
This exposes 2 experimental functions that make it possible to upload a
subregion of a texture from a CoglBuffer by first wrapping the buffer as
a CoglBitmap and then allowing uploading of a subregion from a
CoglBitmap. The new functions are:

cogl_bitmap_new_from_buffer() and
cogl_texture_set_region_from_bitmap()

Actually for now we are exporting this API for practical reasons since
we already had this API internally and it enables a specific feature
that was requested, but it is worth nothing that it's quite likely we
will replace these with functions that don't involve the CoglBitmap API
at some point.

For reference: The CoglBitmap API was actually removed from the 2.0
experimental API reference manual some time ago because the hope was
that we'd come up with a neater replacement. It doesn't seem entirely
clear what the scope of the CoglBitmap api is so it has became a bit of
a dumping ground.  CoglBitmap is used for image loading, as a means to
represent the layout of image data and also internally deals with format
conversions.

Note: Because we are avoiding including CoglBitmap as part of the 2.0
API these functions aren't currently included in the 2.0 reference
manual.

52a5fae136 gles: don't check for glClientActiveTexture
in cogl-ext-functions.h we had one multitexture feature that checked for
the ARB_multitexture extension and if found it then expected to find
glActiveTexture and glClientActiveTexture. The problem is that the
multitexture extension is part of the core GLES 1 and 2 APIs except that
for GLES2 there is no glClientActiveTexture function. By trying to
handle it as one feature that meant that Cogl would fail to check the
multitexture extension which is a hard requirement for Cogl.

The reason this went unnoticed is because Cogl can indirectly end up
linked to an OpenGL library via cairo and so we were finding a
glClientActiveTexture symbol there. This highlights that we should
probably stop using g_module_open (NULL) when checking features and
instead we should use the module we opened in cogl-renderer.c.

03c4b20931 Specify the full filename when g_module_open'ing the GL library
Instead of using g_module_build_path with the short name of the GL
library (eg, "GL") and relying on glib to add the suffix and prefix,
the configure script now directly encodes the full name including the
version number (eg, "libGL.so.1"). This is necessary because distros
don't always install the non-versioned suffix for the library.

The GLES libraries are left without the version suffix because it's
not clear what should be placed here and I can't find any
documentation from Khronos to clarify this. Mesa seems to install a
file called libGLESv2.so.2 but the IMG SDK doesn't install any
versioned library. There is an example of dynamically loading
libGLESv2 in the Chromium source code and that does not use the
version suffix even though it does use the version suffix for GL. This
implies that it's at least fairly normal to load the unversioned name
for GLES.

The CoglPipelineCache is now extended to store templates for state
affecting vertex shaders and combined programs. The GLSL fragend,

When a new pipeline is created it will now get hashed three times if
the GLSL backends are in use (once for the fragend, once for the
vertend and once for the progend). Ideally we should add some way for
the progend to check its cache before the fragends and vertends are
checked so that it can bypass them entirely if it can find a cached
combined program.

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.

d69d49fada pipeline: Unify how the backends store private data
Previously the fragends had a separate private data pointer which was
used by the GLSL and ARBfp fragends to store a tiny struct containing
a single pointer to the ref-counted shader state. The space for the
private data pointer is reserved in all of the pipelines for all of
the potential backends. The vertends and progends however did this
differently by directly storing the pointer to the ref counted data
using cogl_object_set_user_data. This patch unifies the different
methods so that they all use cogl_object_set_user_data and the
fragends don't bother with the separate tiny allocation for the
private data. The private data pointer array has been removed from
CoglPipeline and the corresponding fragend virtual to free the private
data has also been removed because this can instead be done with the
destroy notify from the object user data.

The variable names used have been unified so that all of the vertends
and fragends name their data struct CoglPipelineShaderState and use a
variable called shader_state to refer to it. The progend uses
CoglPipelineProgramState and a variable called program_state.

This should also fix two potential bugs. the ARBfp fragend was
apprently leaking a reference to the private state when it creates the
private data because it was adding a reference before stroring the
pointer to the newly allocated data but the ref count is already set
to 1 on creation. The other potential bug is that the free function
for CoglPipeline was only calling the free_priv virtual for the
currently used fragend of the pipeline. The design of the fragends is
meant to allow a pipeline to have multiple fragend priv datas because
a child pipeline could be attaching its fragend data to the ancestor
and its allowed to pick a different fragend.

cogl-winsys-egl-feature-functions.h wasn't being listed as source and so
it wasn't ending up in dist tarballs.

c3b91da414 fix namespace for cogl_context_egl_get_egl_context
This renames cogl_context_egl_get_egl_context to
cogl_egl_context_get_egl_context to be consistent with other platform
specific APIs.

09e7174b1d Remove cogl_context_set_default API
For cogl 2.0 we don't want to have a default context. In the meantime
we can simply assume that calling cogl_context_new() implicitly
sets that context as the default context before returning.

38b67e2884 onscreen: make platform specific onscreen apis consistent
There were several CoglOnscreen functions named like:
cogl_onscreen_<platform>_blah instead of cogl_<platform>_onscreen_blah
so this patch updates those to be consistent with other platform
specific apis we have in cogl.
