------------------------------- -------------------------------
* The Pango renderer API has been exposed as public API, after
a full rename from PangoClutter to CoglPango, to avoid namespace
collisions with upstream Pango. The Pango font map, renderer and
glyph cache can be used by third party code and depend only on
COGL.
* Both Clutter and COGL only allow including <clutter/clutter.h> * Both Clutter and COGL only allow including <clutter/clutter.h>
and <cogl/cogl.h> directly, respectively. This allows avoiding and <cogl/cogl.h> directly, respectively. This allows avoiding
