* clutter-color.h:
* clutter-color.c: Reimplement ClutterColor as a boxed type;
add convenience API for color handling, like: add, subtract,
shade, HSL color-space conversion, packing and unpacking.
* clutter-private.h: Update ClutterMainContext, and export the
main context pointer here.
* clutter-rectangle.h:
* clutter-rectangle.c: Update the color-related code; make
clutter_rectangle_new() and empty constructor and provide
clutter_rectangle_new_with_color(); provide color setter
and getter API.
* clutter-label.h:
* clutter-label.c: Rename the "font" property to "font-name";
update the color-related code to the new ClutterColor object;
rename clutter_label_new() to clutter_label_new_with_text(),
and add setters and getters for the properties.
* clutter-marshal.list: Add VOID:OBJECT and VOID:BOXED marshallers
generators.

* clutter-stage.c: Rework the API: provide a default constructor
for a singleton object, named clutter_stage_get_default(), which
supercedes the clutter_stage() function in clutter-main; provide
new events: button-press-event, button-release-event,
key-press-event and key-release-event; update the color-related
code;
(clutter_stage_snapshot): Allow negative width and height when
taking a snapshot (meaning: use full width/height).

Remove Units from the public API
With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.
ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.
So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:
- we have to maintain twice the amount of entry points in ClutterActor
- we still do an integer-to-float implicit conversion
- we introduce a weird impedance between pixels and "pixels with
fractionary bits"
- language bindings will have to choose what to bind, and resort
to manually overriding the API
+ *except* for language bindings based on GObject-Introspection, as
they cannot do manual overrides, thus will replicate the entire
set of entry points
For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:
void clutter_actor_set_x (ClutterActor *self,
gfloat x);
void clutter_actor_get_size (ClutterActor *self,
gfloat *width,
gfloat *height);
gfloat clutter_actor_get_height (ClutterActor *self);
etc.
The issues I have identified are:
- we'll have a two cases of compiler warnings:
- printf() format of the return values from %d to %f
- clutter_actor_get_size() taking floats instead of unsigned ints
- we'll have a problem with varargs when passing an integer instead
of a floating point value, except on 64bit platforms where the
size of a float is the same as the size of an int
To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:
- we remove ambiguity in the API with regard to pixels and units
- we remove entry points we get to maintain for the whole 1.0
version of the API
- we make things simpler to bind for both manual language bindings
and automatic (gobject-introspection based) ones
- we have the simplest API possible while still exposing the
capabilities of the underlying GL implementation

Remove Units from the public API
With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.
ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.
So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:
- we have to maintain twice the amount of entry points in ClutterActor
- we still do an integer-to-float implicit conversion
- we introduce a weird impedance between pixels and "pixels with
fractionary bits"
- language bindings will have to choose what to bind, and resort
to manually overriding the API
+ *except* for language bindings based on GObject-Introspection, as
they cannot do manual overrides, thus will replicate the entire
set of entry points
For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:
void clutter_actor_set_x (ClutterActor *self,
gfloat x);
void clutter_actor_get_size (ClutterActor *self,
gfloat *width,
gfloat *height);
gfloat clutter_actor_get_height (ClutterActor *self);
etc.
The issues I have identified are:
- we'll have a two cases of compiler warnings:
- printf() format of the return values from %d to %f
- clutter_actor_get_size() taking floats instead of unsigned ints
- we'll have a problem with varargs when passing an integer instead
of a floating point value, except on 64bit platforms where the
size of a float is the same as the size of an int
To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:
- we remove ambiguity in the API with regard to pixels and units
- we remove entry points we get to maintain for the whole 1.0
version of the API
- we make things simpler to bind for both manual language bindings
and automatic (gobject-introspection based) ones
- we have the simplest API possible while still exposing the
capabilities of the underlying GL implementation

* clutter-color.h:
* clutter-color.c: Reimplement ClutterColor as a boxed type;
add convenience API for color handling, like: add, subtract,
shade, HSL color-space conversion, packing and unpacking.
* clutter-private.h: Update ClutterMainContext, and export the
main context pointer here.
* clutter-rectangle.h:
* clutter-rectangle.c: Update the color-related code; make
clutter_rectangle_new() and empty constructor and provide
clutter_rectangle_new_with_color(); provide color setter
and getter API.
* clutter-label.h:
* clutter-label.c: Rename the "font" property to "font-name";
update the color-related code to the new ClutterColor object;
rename clutter_label_new() to clutter_label_new_with_text(),
and add setters and getters for the properties.
* clutter-marshal.list: Add VOID:OBJECT and VOID:BOXED marshallers
generators.
* clutter-stage.h:
* clutter-stage.c: Rework the API: provide a default constructor
for a singleton object, named clutter_stage_get_default(), which
supercedes the clutter_stage() function in clutter-main; provide
new events: button-press-event, button-release-event,
key-press-event and key-release-event; update the color-related
code;
(clutter_stage_snapshot): Allow negative width and height when
taking a snapshot (meaning: use full width/height).
(clutter_stage_get_element_at_pos): Rename clutter_stage_pick().
* clutter-element.c (clutter_element_paint): Clean up the
stage and color related code.
* clutter-event.h:
* clutter-event.c: Add generic ClutterAnyEvent type; add
clutter_event_new(), clutter_event_copy() and clutter_event_free();
make ClutterEvent a boxed type.
* clutter-main.h:
* clutter-main.c: Remove clutter_stage(); add clutter_main_quit(),
for cleanly quitting from clutter_main(); add multiple mainloops
support; allocate the ClutterCntx instead of adding it to the
stack; re-work the ClutterEvent dispatching.
* clutter-group.c (clutter_group_add), (clutter_group_remove): Keep
a reference on the element when added to a ClutterGroup.
* examples/rects.py
* examples/test.c:
* examples/test-text.c:
* examples/video-cube.c:
* examples/super-oh.c:
* examples/test-video.c: Update.

Eliminate G_CONST_RETURN
The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy.
We always used it to conform to the platform, at least for public-facing
API.
At first I assumed it has something to do with brain-damaged compilers
or with weird platforms where const was not really supported; sadly,
it's something much, much worse: it's a define that can be toggled at
compile-time to remove const from the signature of public API. This is a
truly terrifying feature that I assume was added in the past century,
and whose inception clearly had something to do with massive doses of
absynthe and opium — because any other explanation would make the
existence of such a feature even worse than assuming drugs had anything
to do with it.
Anyway, and pleasing the gods, this dubious feature is being
removed/deprecated in GLib; see bug:
https://bugzilla.gnome.org/show_bug.cgi?id=644611
Before deprecation, though, we should just remove its usage from the
whole API. We should especially remove its usage from Cally's internals,
since there it never made sense in the first place.
