43edfc9400 Clean up clutter-private.h/4
Move the private Backend API to a separate header.

This also allows us to finally move the class vtable and instance
structure to a separate file and plug the visibility hole that left
the Backend class bare for everyone to poke into.

d2bb57c3b2 Emit a critical warning if features are not initialized
If you forgot to call clutter_init() then you currently end up with a
warning saying that the stage cannot be initialized because the backend
does not support multiple stages. Clearly not useful.

We can catch some of the missing initialization in the features API,
since we will likely end up asking for a feature at some point.

bf7e6ae587 Add error reporting for create_context() failures
We kind of assume that stuff will break well before during the
ClutterBackend::create_context() implementation if we fail to create a
GL context. We do, however, have error reporting in place inside the
Backend API to catch those cases. Unfortunately, since we switched to
lazy initialization of the Stage, there can be a case of GL context
creation failure that still leads to a successful initialization - and a
segmentation fault later on. This is clearly Not Good™.

Let's try to catch a failure in all the places calling create_context()
and report back to the user the error in a meaningful way, before
crashing and burning.

79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

As a side note: this commit closes the oldes bug in Clutter's bug
report tool.

5eb6fb74b6 feature: Make sure we have a GL context
Before asking Cogl and ClutterBackend for the list of features we must
have a GL backend ready.

c6fba47a52 Hide clutter_context_get_default()
The clutter_context_get_default() function is private, but shared
across Clutter. For this reason, it should be prefixed by '_' so
that the symbol is hidden from the shared object.

Bug #948 - Remove texture rectangle support

        * clutter/clutter-feature.c:
        * clutter/clutter-feature.h:
        * clutter/clutter-texture.c:
        * clutter/cogl/gl/cogl.c:
* clutter/glx/clutter-glx-texture-pixmap.c:
        Remove support for GL_TEXTURE_RECTANGLE_ARB (now using just regular
        2D textures, with optional npots extension). Simplifys code, + makes
        mipmap & shader support much more sane.

507f04a8f6 Add base initialisation function
Add a semi-private function, called clutter_base_init(), which initialises
the basic Clutter functionalities (at the moment, just the GLib type system)
without calling in the backend-specific code. This function is only useful
for gtk-doc, to introspect the library when generating documentation for
signals, properties and class hierarchy.

Also, change the documentation build system to use clutter_base_init() when
launching the scanner program.

Avoid clutter segfaulting when used without invoking
	clutter_init().  This is needed when using api documentation
	tools and every other tool relying on the GObject
	introspection API (esp. on a headless box).  see the
	note in clutter/clutter-feature.c:clutter_feature_init
	for a full explanation.

	* clutter/clutter-feature.c: Call clutter_feature_init()
	when needed by one of the accessors of the features
	structure.

	* clutter/clutter-main.c:
	* clutter/clutter-private.h: Remove clutter_feature_init()
	public declaration: the features support check is done the
	first time a feature is needed.

	* clutter/clutter-main.c: Do not ever access the clutter
	main context pointer directly; instead, obtain a pointer
	to it via clutter_context_get_default(), which will always
	return something valid.

* configure.ac: Enable debug messages also when
	--enable-debug is set to "minimum".

	* clutter/Makefile.am:
	* clutter/clutter-debug.h: Move all debugging macros inside
	this private header; make all debug macros depend on the
	CLUTTER_ENABLE_DEBUG compile time define, controlled by
	the --enable-debug configure switch; add G_LOG_DOMAIN define.

	* clutter/clutter-main.c: Clean up the debug stuff; add
	command line argument parsing using GOption; the debug
	messages now are triggered like this:

	  CLUTTER_DEBUG=section:section:... clutter-app
	
	or like this:

	  clutter-app --clutter-debug=section:section:...
	
	where "section" is one of the sections listed in clutter-main.c,
	or "all", for all sections; each section is bound to a flag,
	which can be used to define a domain when adding a debug note
	using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
	just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
	CLUTTER_NOTE() is used like this:

	  CLUTTER_NOTE (DOMAIN, log-function);
	
	where log function is g_printerr(), g_message(), g_warning(),
	g_critical() or directly g_log() - for instance:

	  CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));

	will print the warning only if the "pango" flag has been
	set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
	command line argument.

	similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
	command line switch; also, the --display and --screen command
	line switches have been added: the first overrides the DISPLAY
	envvar and the second controls the X screen used by Clutter to
	get the root window on the display.

	* clutter/clutter-main.h:
	* clutter/clutter-main.c: Add extended support for GOption
	in Clutter; use clutter_init_with_args() to let Clutter
	parse your own command line arguments; use instead
	clutter_get_option_group() to get the GOptionGroup used by
	Clutter if you want to do the parsing yourself with
	g_option_context_parse(). The init sequence has been verified,
	updated and moved into common functions where possible.

	* clutter/pango/pangoclutter-render.c:
	* clutter/*.c: Include "clutter-debug.h" where needed; use
	CLUTTER_NOTE() instead of CLUTTER_DBG().

	* examples/super-oh.c: Use the new clutter_init_with_args()
	function, and add a --num-hands command line switch to
	the SuperOH example code controlling the number of hands at
	runtime.

* clutter/clutter-behaviour-path.h:
	* clutter/clutter-behaviour-path.c: Add "since" strings; add
	a "knot" property which can be used to append a knot to the path;
	fix apidoc.

	* clutter/clutter-alpha.c: Add "since" strings.

	* clutter/clutter-feature.c: Add apidoc.

	* clutter/clutter-behaviour-opacity.c: Add the "opacity-start"
	and "opacity-end" properties; rewrite constructor to use them.

* clutter/clutter-alpha.h:
	* clutter/clutter-alpha.c: Add a data parameter to
	the ClutterAlphaFunc; add a data+destroy parameter
	to clutter_alpha_set_func() and to clutter_alpha_new(),
	and turned the latter into clutter_alpha_new_full();
	add a simple, empty constructor clutter_alpha_new().

	These changes makes writing bindings a tad more easy,
	as bindings require passing their own functions in
	order to call the real alpha function.

	* clutter/clutter-behaviour.h: Clean up the header.

	* clutter/clutter-behaviours.[ch]:
	* clutter/clutter-behaviour-opacity.[ch]:
	* clutter/clutter-behaviour-path.[ch]:
	* clutter/clutter-behaviour-scale.[ch]: Split the
	ClutterBehaviourPath, ClutterBehaviourOpacity and
	ClutterBehaviourScale into their own files as they
	have been growing a bit. Fix ClutterBehaviourPath
	API.

	* clutter/clutter-media.h: Remove the commented
	"metadata_available" signal: gtk-doc chokes up on that.

	* clutter/clutter-timeline.h:
	* clutter/clutter-timeline.c: Remove the useless
	ClutterTimelineAlphaFunc signature; add missing accessor
	methods for the properties; clean up a bit.

	* clutter/clutter-util.h:
	* clutter/clutter-util.c: Remove unneeded function
	clutter_util_can_create_texture().

	* clutter/clutter-feature.h: Sync the name of
	clutter_feature_get_all() with the name declared
	in clutter-feature.h.

	* clutter/Makefile.am:
	* clutter/clutter.h: Update.

	* examples/behave.c: Update to the new ClutterAlpha
	constructor.

	* examples/super-oh.c: Use the right pointer and avoid
	the compiler making a fuss about it.

* clutter/clutter-actor.h:
        * clutter/clutter-actor.c:
        Add new API clutter_actor_move_by(), clutter_actor_get_size()

        * clutter/clutter-alpha.c:
        * clutter/clutter-alpha.h:
        Add clutter alpha sine func

        * clutter/clutter-behaviours.h:
        * clutter/clutter-behaviours.c:
        Add a basic scale behaviour (needs work)

        * examples/behave.c: (main):
        More playing with new behaviour functionality

        * clutter/clutter-feature.c:
        * clutter/clutter-feature.h:
        * clutter/clutter-main.c:
        Add new experimental sync to vblank code
        Set env CLUTTER_VBLANK=none to disable.

* clutter/clutter-feature.c: No need to call clutter_feature_init()
	each time: it's private and should never be seen from the outside;
	add a warning, just in case something screws up and calls it more
	than once.

* clutter/clutter-private.h: Move clutter_feature_init()
	declaration here: you shouldn't even need to initialise
	features yourself.

	* clutter/clutter-feature.c: call clutter_feature_init()
	each time you try to access the feature list; add a static
	lock around the feature flags container; add api documentation.

	* clutter/clutter-feature.h: Add a type for the feature flags
	to make bindings happy.

* clutter/Makefile.am:
        * clutter/clutter-feature.c:
        * clutter/clutter-feature.h:

        Add new funcs for checking for available runtime GL
        extensions.

        * clutter/clutter-clone-texture.c:
        * clutter/clutter-texture.c:

        Add support for non power of two textures
       if GL_TEXTURE_RECTANGLE_ARB extension available ( at runtime ).
       Should lower texture memory needs a little.
