6436cd073d Declare interface types as void and remove cast macros
This declares the interface types CoglFramebuffer, CoglBuffer,
CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when
including the public cogl.h header so that users don't have to use lots
of C type casts between instance types and interface types.

This also removes all of the COGL_XYZ() type cast macros since they do
nothing more than compile time type casting but it's less readable if
you haven't seen that coding pattern before.

Unlike with gobject based apis that use per-type macros for casting and
performing runtime type checking we instead prefer to do our runtime
type checking internally within the front-end public apis when objects
are passed into Cogl. This greatly reduces the verbosity for users of
the api and may help reduce the chance of excessive runtime type
checking that can sometimes be a problem.

(cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7)

Since we can't break the 1.x api this version of the patch actually
defines compatible NOP macros within deprecated/cogl-type-casts.h

e4f24dba75 framebuffer: remove attribute drawing apis
Almost nothing draws attributes directly and for those things that do
it's trivial to adapt them to instead draw via the cogl_primitive api.
This simplifies the Cogl api a bit.

Symbols changed names, %1 makes gtk-doc sad and some referenced symbols
were missing in the -sections.txt file.

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.

4c49f83056 meta-texture: Support CLAMP_TO_EDGE
cogl_meta_texture_foreach_in_region() now directly supports
CLAMP_TO_EDGE wrap modes. This means the cogl_rectangle code will be
able to build on this and makes the logic accessible to anyone
developing custom primitives that need to support meta textures.

1d8fd64e1c meta-texture: This publicly exposes CoglMetaTexture
CoglMetaTexture is an interface for dealing with high level textures
that may be comprised of one or more low-level textures internally. The
interface allows the development of primitive drawing APIs that can draw
with high-level textures (such as atlas textures) even though the
GPU doesn't natively understand these texture types.

There is currently just one function that's part of this interface:
cogl_meta_texture_foreach_in_region() which allows an application to
resolve the internal, low-level textures of a high-level texture.
cogl_rectangle() uses this API for example so that it can easily emulate
the _REPEAT wrap mode for textures that the hardware can't natively
handle repeating of.
