4f6fe6f0e2 Fixes for --disable-glib
This fixes some problems which were stopping --disable-glib from
working properly:

• A lot of the public headers were including glib.h. This shouldn't be
  necessary because the API doesn't expose any glib types. Otherwise
  any apps would require glib in order to get the header.

• The public headers were using G_BEGIN_DECLS. There is now a
  replacement macro called COGL_BEGIN_DECLS which is defined in
  cogl-types.h.

• A similar fix has been done for G_GNUC_NULL_TERMINATED and
  G_GNUC_DEPRECATED.

• The CFLAGS were not including $(builddir)/deps/glib which was
  preventing it finding the generated glibconfig.h when building out
  of tree.

13f228fe69 Remove all remaining _EXP suffix defines
To delimit which symbols were considered experimental we used to use
some preprocessor defines to gives experimental symbols an _EXP suffix
so that anyone monitoring the ABI for changes would easily be able to
discount changes made to clearly experimental functions.

These days we simply rely on the gtk-doc "Stability: unstable"
annotation to serve this purpose because changing the actual symbol name
made it slightly more awkward to debug Cogl using GDB and was an extra
mechanical step we decided we could do without.

This patch removes the last remaining _EXP suffix defines in Cogl

54735dec84 Switch use of primitive glib types to c99 equivalents
The coding style has for a long time said to avoid using redundant glib
data types such as gint or gchar etc because we feel that they make the
code look unnecessarily foreign to developers coming from outside of the
Gnome developer community.

Note: When we tried to find the historical rationale for the types we
just found that they were apparently only added for consistent syntax
highlighting which didn't seem that compelling.

Up until now we have been continuing to use some of the platform
specific type such as gint{8,16,32,64} and gsize but this patch switches
us over to using the standard c99 equivalents instead so we can further
ensure that our code looks familiar to the widest range of C developers
who might potentially contribute to Cogl.

So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this
switches all Cogl code to instead use the int{8,16,32,64}_t and
uint{8,16,32,64}_t c99 types instead.

Instead of gsize we now use size_t

For now we are not going to use the c99 _Bool type and instead we have
introduced a new CoglBool type to use instead of gboolean.

09642a83b5 Removes all remaining use of CoglHandle
Removing CoglHandle has been an on going goal for quite a long time now
and finally this patch removes the last remaining uses of the CoglHandle
type and the cogl_handle_ apis.

Since the big remaining users of CoglHandle were the cogl_program_ and
cogl_shader_ apis which have replaced with the CoglSnippets api this
patch removes both of these apis.

(cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0)

  Since the original patch was done after removing deprecated API
  this back ported patch doesn't affect deprecated API and so
  actually this cherry-pick doesn't remove all remaining use of
  CoglHandle as it did for the master branch of Cogl.

ee940a3d0d Move all types/prototypes from cogl.h -> cogl[1]-context.h
So we can get to the point where cogl.h is merely an aggregation of
header includes for the 1.x api this moves all the function prototypes
and type definitions into a cogl-context.h and a new cogl1-context.h.

Ideally no code internally should ever need to include cogl.h as it just
represents the public facing header for accessing the 1.x api which
should only be used by Clutter.

92c3063014 framebuffer: Add cogl_framebuffer draw methods
This adds cogl_framebuffer_ apis for drawing attributes and primitives
that replace corresponding apis that depend on the default CoglContext.
This is part of the on going effort to adapt the Cogl api so it no
longer depends on a global context variable.

All the new drawing functions also take an explicit pipeline argument
since we are also aiming to avoid being a stateful api like Cairo and
OpenGL. Being stateless makes it easier for orthogonal components to
share access to the GPU. Being stateless should also minimize any
impedance miss-match for those wanting to build higher level stateless
apis on top of Cogl.

Note: none of the legacy, global state options such as
cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or
cogl_program_use() are supported by these new drawing apis and if set
will simply be silently ignored.

8cf76ee36b primitive: Add n_indices arg to _set_indices function
When associating indices with a CoglPrimitive you are now forced to
specify the number of indices that should be read when drawing.

It's easy to forget to call cogl_primitive_set_n_vertices() after
associating indices with a primitive (and anyway you can see that someone
could be led to believe Cogl can determine that implicitly somewhow) so
this should avoid a lot of mistakes with using the API.

We'd expect that setting indices and updating the n_vertices property
would go hand in hand 99% of the time anyway so this change should
be more convenient as well as less error prone.

This patch adds some documentation for cogl_primitive_set_indices and
cogl_primitive_get/set_n_vertices. It also tries to clarify how the
CoglPrimitive:n_vertices property is updated and what that property
means in relation to other functions too.

3c1e83c7f5 Don't pass around NULL terminated CoglAttribute arrays
For the first iteration of the CoglAttribute API several of the new
functions accepted a pointer to a NULL terminated list of CoglAttribute
pointers - probably as a way to reduce the number of arguments required.
This style isn't consistent with existing Cogl APIs though and so we now
explicitly pass n_attributes arguments and don't require the NULL
termination.

ce7c06dc03 Rename CoglVertexArray to CoglAttributeBuffer
This is part of a broader cleanup of some of the experimental Cogl API.
One of the reasons for this particular rename is to switch away from
using the term "Array" which implies a regular, indexable layout which
isn't the case. We also want to have a strongly implied relationship
between CoglAttributes and CoglAttributeBuffers.

87c990a29c cogl: s/Cogl*Vertex/CoglVertex*/
We have a bunch of experimental convenience functions like
cogl_primitive_p2/p2t2 that have corresponding vertex structures but it
seemed a bit odd to have the vertex annotation e.g. "P2T2" be an infix
of the type like CoglP2T2Vertex instead of be a postfix like
CoglVertexP2T2. This switches them all to follow the postfix naming
style.

a03a5814e7 primitive: Adds convenience constructors
This adds convenience primitive constructors named like:
  cogl_primitive_new_p3 or
  cogl_primitive_new_p3c4 or
  cogl_primitive_new_p3t2c4
where the letters correspond to the interleved vertex attributes layouts
such as CoglP3Vertex which is a struct with 3 float x,y,z members for
the [p]osition, or CoglP3T2C4Vertex which is a struct with 3 float x,y,z
members for the [p]osition, 2 float s,t members for the [t]exture
coordinates and 4 unsigned byte r,g,b,a members for the [c]olor.

The hope is that people will find these convenient enough to replace
cogl_polygon.

9498d505dd cogl: Adds experimental CoglPrimitive API
A CoglPrimitive is a retainable object for drawing a single primitive,
such as a triangle strip, fan or list.

CoglPrimitives build on CoglVertexAttributes and CoglIndices which
themselves build on CoglVertexArrays and CoglIndexArrays respectively.

A CoglPrimitive encapsulates enough information such that it can be
retained in a queue (e.g. the Cogl Journal, or renderlists in the
future) and drawn at some later time.
