cogl-pango: Use a seperate cache of pipelines Instead of creating just two materials (one for texturing and one for solid primitives) the pango renderer now maintains a cache of pipelines. The display list can request a pipeline for a texture from the cache. The same pipeline cache is used by all display lists so that the pipelines can be shared. This avoids changing the texture on the material during a paint run.

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.

cogl-pango: Updates to no longer require a default context This updates the Cogl Pango api to no longer require a default context and also cleans up the public api a bit. The CoglPangoRenderer type has been made private to be consistent with other pango backends where the renderer is merely an implementation detail. The drawing apis such as cogl_pango_render_layout where made more consistent with other pango backend apis so we now have replacements like cogl_pango_show_layout(). Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit bba2defe8c08a498b2dcb84bcf5b5a33f16eed27) Note: API changes were reverting in cherry-picking this patch

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. Reviewed-by: Neil Roberts <neil@linux.intel.com> (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.
