a79d6228aa Remove the last few fixed-point entry points
The last fixed-point entry points are just a few, and trivial. The
end user is expected to do the conversion using the CoglFixed type
and macros.

4bed539b21 Add more ActorBox utility methods
ActorBox should have methods for easily extracting the X and Y
coordinates of the origin, and the width and height separately.

These methods will make it easier for high-level language bindings
to manipulate ActorBox instances and avoid the Geometry type.

275f292ab9 Add accessors for the boxed types
The Vertex and ActorBox boxed types are meant to be used across
the API, but are fairly difficult to bind. Their memory management
is also unclear, and has to go through the indirection of
g_boxed_copy() and g_boxed_free().

e1cac4fece Fix clutter_redraw() to match the redraw cycle
The clutter_redraw() function is used by embedding toolkits to
force a redraw on a stage. Since everything is performed by
toggling a flag inside the Stage itself and then letting the
master clock advance, we need a ClutterStage method to ensure
that we start the master clock and redraw.

33f5fe73b3 [stage] Rename fullscreen methods
The clutter_stage_fullscreen() and clutter_stage_unfullscreen() are
a GDK-ism. The underlying implementation is already using an accessor
with a boolean parameter.

This should take the amount of collisions between properties, methods
and signals to zero.

41e85f3073 introspection-friendly ClutterEvent accessors
ClutterEvent is not really gobject-introspection friendly because
of the whole discriminated union thing. In particular, if you get
a ClutterEvent in a signal handler, you probably can't access the
event-type-specific fields, and you probably can't call methods
like clutter_key_event_symbol() either, because you can't cast the
ClutterEvent to a ClutterKeyEvent.

The cleanest solution is to turn every accessor into ClutterEvent
methods, accepting a ClutterEvent* and internally checking the event
type.

Fixes bug:

54d8aadf1d [cogl] Move the texture filters to be a property of the material layer
The texture filters are now a property of the material layer rather
than the texture object. Whenever a texture is painted with a material
it sets the filters on all of the GL textures in the Cogl texture. The
filter is cached so that it won't be changed unnecessarily.

The automatic mipmap generation has changed so that the mipmaps are
only generated when the texture is painted instead of every time the
data changes. Changing the texture sets a flag to mark that the
mipmaps are dirty. This works better if the FBO extension is available
because we can use glGenerateMipmap. If the extension is not available
it will temporarily enable automatic mipmap generation and reupload
the first pixel of each slice. This requires tracking the data for the
first pixel.

The COGL_TEXTURE_AUTO_MIPMAP flag has been replaced with
COGL_TEXTURE_NO_AUTO_MIPMAP so that it will default to
auto-mipmapping. The mipmap generation is now effectively free if you
are not using a mipmap filter mode so you would only want to disable
it if you had some special reason to generate your own mipmaps.

ClutterTexture no longer has to store its own copy of the filter
mode. Instead it stores it in the material and the property is
directly set and read from that. This fixes problems with the filters
getting out of sync when a cogl handle is set on the texture
directly. It also avoids the mess of having to rerealize the texture
if the filter quality changes to HIGH because Cogl will take of
generating the mipmaps if needed.

0d5e17ecd1 [units] Rework Units into logical distance value
Units as they have been implemented since Clutter 0.4 have always been
misdefined as "logical distance unit", while they were just pixels with
fractionary bits.

Units should be reworked to be opaque structures to hold a value and
its unit type, that can be then converted into pixels when Clutter needs
to paint or compute size requisitions and perform allocations.

The previous API should be completely removed to avoid collisions, and
a new type:

        ClutterUnits

should be added; the ability to install GObject properties using
ClutterUnits should be maintained.

9c7afe0c5b [timeline] Remove the concept of frames from timelines
Timelines no longer work in terms of a frame rate and a number of
frames but instead just have a duration in milliseconds. This better
matches the working of the master clock where if any timelines are
running it will redraw as fast as possible rather than limiting to the
lowest rated timeline.

Most applications will just create animations and expect them to
finish in a certain amount of time without caring about how many
frames are drawn. If a frame is going to be drawn it might as well
update all of the animations to some fraction of the total animation
rather than rounding to the nearest whole frame.

The 'frame_num' parameter of the new-frame signal is now 'msecs' which
is a number of milliseconds progressed along the
timeline. Applications should use clutter_timeline_get_progress
instead of the frame number.

Markers can now only be attached at a time value. The position is
stored in milliseconds rather than at a frame number.

test-timeline-smoothness and test-timeline-dup-frames have been
removed because they no longer make sense.

ffd5fb172b [docs] Rework the API reference version generation
Clutter copies the gtk-doc from the usual gtk+ template, and
has a version.xml.in containing only:

  @VERSION@

Without a newline at the end. Unfortunately, it appears that
autoconf has started adding a newline to the generated version.xml
which then is used as the payload for the "version" XML entity.

Instead of using a secondary file we can make configure generate
the whole clutter-docs.xml and cogl-docs.xml files from a template;
this way we also get the ability to substitute more autoconf variables
into the documentation -- if needs be.

67544f38d4 [cogl-vertex-buffer] Add cogl_vertex_buffer_indices_get_for_quads
This function can be used as an efficient way of drawing groups of
quads without using GL_QUADS. It generates a VBO containing the
indices needed to render using pairs of GL_TRIANGLES. The VBO is
globally cached so that it only needs to be uploaded whenever more
indices are requested than ever before.

4afe1e9a8b [actor] Add allocate_available_size()
The allocate_available_size() method is a convenience method in
the same spirit as allocate_preferred_size(). While the latter
will allocate the preferred size of an actor regardless of the
available size provided by the actor's parent -- and thus it's
suitable for simple fixed layout managers like ClutterGroup -- the
former will take into account the available size provided by the
parent and never allocate more than that; it is, thus, suitable
for simple fluid layout managers.

12c8ff8606 [cogl] Remove cogl_{create,destroy}_context from the public API
cogl_create_context is dealt with internally when _cogl_get_default context
is called, and cogl_destroy_context is currently never called.

It might be nicer later to get an object back when creating a context so
Cogl can support multiple contexts, so these functions are being removed
from the API until we get a chance to address context management properly.

For now cogl_destroy_context is still exported as _cogl_destroy_context so
Clutter could at least install a library deinit handler to call it.

6bb6686666 [cogl-vertex-buffers] Support putting index arrays into VBOS
It's now possible to add arrays of indices to a Cogl vertex buffer and
they will be put into an OpenGL vertex buffer object. Since it's quite
common for index arrays to be static it saves the OpenGL driver from
having to validate them repeatedly.

This changes the cogl_vertex_buffer_draw_elements API: It's no longer
possible to provide a pointer to an index array at draw time. So
cogl_vertex_buffer_draw_elements now takes an indices identifier that
should correspond to an idendifier returned when calling
cogl_vertex_buffer_add_indices ()

f322da3794 [material] Reduce the material API in preperation for releasing Clutter 1.0
There were a number of functions intended to support creating of new
primitives using materials, but at this point they aren't used outside of
Cogl so until someone has a usecase and we can get feedback on this
API, it's being removed before we release Clutter 1.0.

f28d5e481b [cogl-material] Removes all the API made redundant by the blend strings API
This removes the following API:
  cogl_material_set_blend_factors
  cogl_material_set_layer_combine_function
  cogl_material_set_layer_combine_arg_src
  cogl_material_set_layer_combine_arg_op

These were rather awkward to use, so since it's expected very few people are
using them at this point and it should be straight forward to switch over
to blend strings, the API is being removed before we release Clutter 1.0.

33994caa71 [cogl-material] Support string based blending and layer combine descriptions
Setting up layer combine functions and blend modes is very awkward to do
programatically.  This adds a parser for string based descriptions which are
more consise and readable.

E.g. a material layer combine function could now be given as:
  "RGBA = ADD (TEXTURE[A], PREVIOUS[RGB])"
or
  "RGB = REPLACE (PREVIOUS)"
  "A = MODULATE (PREVIOUS, TEXTURE)"

The simple syntax and grammar are only designed to expose standard fixed
function hardware, more advanced combining must be done with shaders.

This includes standalone documentation of blend strings covering the aspects
that are common to blending and texture combining, and adds documentation
with examples specific to the new cogl_material_set_blend() and
cogl_material_layer_set_combine() functions.

Note: The hope is to remove the now redundant bits of the material API
before 1.0

36cfb60307 [cogl] Remove the COGL{enum,int,uint} typedefs
COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.

The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.

The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.

cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.

a5cdfdfd87 [cogl-offscreen] Cleans up the cogl offscreen API and adds documentation
There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.

There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.

The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.

The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.

This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.

216373047b [animation] Enhance consistency of the Animation API
The Animation API should follow this pattern:

  - functions with an Interval as part of the arguments should have
    "interval" inside their name, e.g.:

      clutter_animation_bind_interval
      clutter_animation_update_interval

  - functions dealing with property names should have "property"
    inside their name, e.g.:

      clutter_animation_has_property
      clutter_animation_unbind_property

    - unless -

  - functions dealing with a property and its value should not
    have any modifier, e.g.:

      clutter_animation_bind

The change from update_property() to update_interval() frees up
clutter_animation_update(), to be added at a later date.

89e3e3a4cc [animation] Add vector variants for ::animate()
Bug 1438 - Implicit Animation API could use animatev variants

The clutter_actor_animate* family of functions use va_lists to
handle the property/value pairs for the final state of the
animation.

Language bindings have problems with variadic arguments functions,
and usually prefer vector-based API which allow a greater level
of control and conversion from native data types.

For each variadic arguments function in the clutter_actor_animate*
family there should be a vector-based version that takes:

  - the number of property/value pairs
  - a constant array of constant strings
  - an array of GValues

Most of the internal implementation can be refactored from the
current one, thus both the var_args and the vector entry points
share a common implementation of the code; then, both versions
of the API are just loops over a list of arguments.

7d674db9d2 Clean up of the ClutterColor API
The ClutterColor API has some inconsistencies:

  - the string deserialization function does not match the rest of
    the conversion function naming policy; the naming should be:

        clutter_color_parse()   ->      clutter_color_from_string()

    and the first parameter should be the ClutterColor that will
    be set from the string, not the string itself (a GDK-ism).

  - the fixed point API should not be exposed, especially in the
    form of ClutterFixed values

  - the non-fixed point HLS conversion functions do not make any
    sense. The values returned should be:

      hue        := range [ 0, 360 ]
      luminance  := range [ 0,   1 ]
      saturation := range [ 0,   1 ]

    like the current fixed point API does. Returning a value in
    the [ 0, 255 ] range is completely useless

  - the clutter_color_equal() should be converted for its use inside
    a GHashTable; a clutter_color_hash() should be added as well

  - the second parameter of the clutter_color_shade() function should
    be the shading factor, not the result (another GDK-ism). this way
    the function call can be translated from this:

      color.shade(out result, factor)

    to the more natural:

      color.shade(factor, out result)

This somewhat large commit fixes all these issues and updates the
internal users of the API.

af0726480c [cogl-matrix] Documents that CoglMatrix members should be considered read only
In the future if we want to annotate matrices with internal flags, and add
caching of the inverse matrix then we need to ensure that all matrix
modifications are done by cogl_matrix API so we'd know when to dirty the
cache or update the flags.

This just adds documentation to that effect, and assuming the most likley
case where someone would try and directly write to matrix members would
probably be to load a constant matrix other than the identity matrix; I
renamed cogl_matrix_init_from_gl_matrix to cogl_matrix_init_from_array to
make it seem more general purpose.

03018f0c2a [Cogl] Renames cogl_paint_init to cogl_clear and adds a cogl_disable_fog function
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.

It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.

Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.

9cf02bfdb9 [text] Rename :alignment to :line-alignment
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.

Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.

3e68b23ea8 Merge branch 'scale-center'
Bug 1349 - Using the anchor point to set the scale center is messy

The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.

The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.

The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.

418fb995c8 Replace clutter_set_use_mipmapped_text with clutter_set_font_flags
The hope is that this function makes it easier to extend the font
settings with more flags without having to add a function for every
setting.

A new flag for enabling hinting has been added. If set, this changes
the font options on the global PangoContext and any newly created
PangoContexts. The options are only set if the flag is changed from
the default so it won't override any detailed setting chosen by the
backend.

134edac82c Bug 1361 - Unused ClutterStage::get_resolution() methods
The clutter_stage_get_resolution() and fixed-point API are just
shorthands for:

        clutter_backend_get_resolution (default_backend);

And as such do not fit at all in the ClutterStage class. The only
reason for their existence was the ClutterUnit conversion macros,
which have now been fixed to use the default backend through a
function call instead.

Thus, we can safely remove the stage entry points.

e338245827 Renames the mesh api to the "vertex buffer api".
This better reflects the fact that the api manages sets of vertex attributes,
and the attributes really have no implied form. It is only when you use the
attributes to draw that they become mesh like; when you specify how they should
be interpreted, e.g. as triangle lists or fans etc. This rename frees up the
term "mesh", which can later be applied to a concept slightly more fitting.
E.g. at some point it would be nice to have a higher level abstraction that
sits on top of cogl vertex buffers that adds the concept of faces. (Somthing
like Blender's mesh objects.) There have also been some discussions over
particle engines, and these can be defined in terms of emitter faces; so some
other kind of mesh abstraction might be usefull here.

Okey; to summarise the changes...

We have converted Clutter and Cogl over to using floating point internally
instead of 16.16 fixed, but we have maintained the cogl-fixed API as a
utility to applications in case they want to implement their own optimizations.

The Clutter API has not changed (though ClutterFixed and ClutterUnit are now
internally floats) but all Cogl entry points have been changed to accept floats
now instead of CoglFixed.

To summarise the rationale...

There have been a number of issues with using fixed point though out Clutter
and Cogl including: lack of precision, lack of range, excessive format
conversion (GPUs tend to work nativly with IEEE floats) and maintainability.
One of the main arguments for fixed point - performance - hasn't shown
itself to be serious in practice so far since we seem to be more limited
by GPU performance and making improvements regarding how we submit data to
OpenGL[ES]/the GPU has had a more significant impact.

Ref: The recent multiple rectangle queuing changes + the
cogl-texture-agressive-batching branch which show significant performance
gains, and that recent tests on the ipodtouch (ARM + MBX) also showed no
loss of performance running with floats.

So finally; please forgive the inevitable fallout, this is a far reaching
change. There are still a few known issues with the fixed to float
conversion but enough works for all our conformance tests to pass, and the
remaining issues hopefully wont be too tricky to solve. For reference two
tags will be available either side of this change: "cogl-fixed-end" and
"cogl-float-start"

In order to unify alpha functions and animation modes in ClutterAlpha
we should be able to register alpha functions and get a logical id
for them; the logical id will then be available to be used by
clutter_alpha_set_mode().

The registration requires API changes in ClutterAlpha constructors
and methods. It also provides the chance to shift ClutterAlpha
towards the use of animations modes only, and to alpha functions
as a convenience API for language bindings alone.
