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.

1cd313477b [clutter-actor] Use G_STMT_START/END instead of do { } while (0)
In the TRANSFORM_ABOUT_ANCHOR_COORD macro it now uses G_STMT_START and
G_STMT_END instead of directly using do/while because it's more
readable.

d7c275f5e5 [cogl-texture] Fix order of tex coords when compensating for waste
When drawing a texture with waste in _cogl_multitexture_unsliced_quad
it scales the texture coordinates so that the waste is not
included. However the formula was the wrong way around so it was
calculating as if the texture coordinates are ordered x1,x2,y1,y2 but
it is actually x1,y1,x2,y2.

eda1d08f76 Fix rectangles_with_multitexture_coords for sliced without tex coords
When the texture is sliced it drops back to a fallback function and
passes it the texture coordinates from the rectangle. However if no
tex coords are given it would crash. Now it passes the default
0.0->1.0 tex coords instead.

7df1987652 Fix _cogl_texture_unsliced_quad when no texture coordinates are given
If no texture coordinates are given then texture_unsliced_quad tries
to generate its own coordinates. However it also tries to read the
texture coordinates to check if they are in [0.0,1.0] range so it will
crash before it reaches that.

6b9da72ab0 Directly set backend font options in clutter_set_font_flags
Instead of having a separate set of font options that override the
backend options when clutter_set_font_flags is called, it now just
directly sets the backend font options. So now the font flags are just
a convenience wrapper around the backend font options.

This also makes the ClutterText labels automatically update when the
font flags are changed because they will respond to the 'font-changed'
signal from the backend.

89b0b00dd1 Listen for the font-changed signal on the backend in ClutterText
Whenever a ClutterText is created it now connects to the font-changed
signal. When it is emitted the layout cache is dirtied and a relayout
is queued. That way changes to the font options or resolution will
cause an immediate update to the labels in the scene.

86e95a779a Remove CloneTexture from the API
ClutterClone supercedes ClutterCloneTexture, since it can clone
every kind of actor -- including composite ones.

This is another "brain surgery with a shotgun" kind of commit: it
removes CloneTexture and updates every test case using CloneTexture
to ClutterClone. The API fallout is minimal, luckily for us.

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.

28f9749e8e clutter-{clone-,}texture weren't updating their material opacity.
cogl_set_source_color4ub was previously used to set a transparent
white source color according to the actors opacity, but since
cogl_set_source_color now always implies you want a solid fill we
we use cogl_material_set_color4ub to achieve the same result.

60e81f0fda Normalizes gl vs gles code in preperation for synching material changes
This changes all GLES code to use the OpenGL function names instead of
the cogl_wrap_* names. For GLES2 we now define the OpenGL name to point
to the wrapper, as opposed to defining the wrapper to point to the
OpenGL name for GLES1.

I've also done a quick pass through gl/cogl.c and gles/cogl.c to make
them more easily comparable. (most of the code is now identical)

5985eef44c Fully integrates CoglMaterial throughout the rest of Cogl
This glues CoglMaterial in as the fundamental way that Cogl describes how to
fill in geometry.

It adds cogl_set_source (), which is used to set the material which will be
used by all subsequent drawing functions

It adds cogl_set_source_texture as a convenience for setting up a default
material with a single texture layer, and cogl_set_source_color is now also
a convenience for setting up a material with a solid fill.

"drawing functions" include, cogl_rectangle, cogl_texture_rectangle,
cogl_texture_multiple_rectangles, cogl_texture_polygon (though the
cogl_texture_* funcs have been renamed; see below for details),
cogl_path_fill/stroke and cogl_vertex_buffer_draw*.

cogl_texture_rectangle, cogl_texture_multiple_rectangles and
cogl_texture_polygon no longer take a texture handle; instead the current
source material is referenced. The functions have also been renamed to:
cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords
and cogl_polygon respectivly.

Most code that previously did:
  cogl_texture_rectangle (tex_handle, x, y,...);
needs to be changed to now do:
  cogl_set_source_texture (tex_handle);
  cogl_rectangle_with_texture_coords (x, y,....);

In the less likely case where you were blending your source texture with a color
like:
  cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */
  cogl_texture_rectangle (tex_handle, x, y,...);
you will need your own material to do that:
  mat = cogl_material_new ();
  cogl_material_set_color4ub (r,g,b,a);
  cogl_material_set_layer (mat, 0, tex_handle));
  cogl_set_source_material (mat);

Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use
cog_rectangle_with_texure_coords since these are the coordinates that
cogl_rectangle will use.

For cogl_texture_polygon; as well as dropping the texture handle, the
n_vertices and vertices arguments were transposed for consistency. So
code previously written as:
  cogl_texture_polygon (tex_handle, 3, verts, TRUE);
need to be written as:
  cogl_set_source_texture (tex_handle);
  cogl_polygon (verts, 3, TRUE);

All of the unit tests have been updated to now use the material API and
test-cogl-material has been renamed to test-cogl-multitexture since any
textured quad is now technically a test of CoglMaterial but this test
specifically creates a material with multiple texture layers.

Note: The GLES backend has not been updated yet; that will be done in a
following commit.

86e4e89bf1 Rename ActorClone to Clone/2
Step two: rename the object and its methods.

practises; rename :clone-source to :source; add a setter method
for the :source property; take a reference on the source actor
to avoid it disappearing while we're still accessing it.

2be9cdc267 [timeline] Documentation and comment fixes
The long description of the ClutterTimeline class is very C
developer-oriented. Since many language bindings will refer to
the C API reference we should probably be more verbose and
language agnostic -- at least in the class description.

The methods documentation also requires a little pass to increase
the consistency of the terminology, the grammar and the syntax.

Finally, comments never killed anyone.

763de185e9 [timeline] Create markers hash tables on demand

to the marker API itself, and adds the relative checks.

1e071ed859 [timeline] Limit timelines to 1000 frames per second
Since we are using milliseconds granularity to integrate timelines
with the GLib main loop, we cannot allow values of the :fps
property bigger than 1000. This means validating the fps value both
in the GParamSpec and the clutter_timeline_set_speed() accessor
function.

This should also fix floating point exceptions when trying to
perform "n_frames = milliseconds / (1000 / fps)".

54f4ed775c Set the SYNC_MATRICES flag when a stage is first realized
The stage will usually be painted before the first ConfigureNotify
arrives so we need to set the SYNC_MATRICES flag to ensure that the
viewport will be correct for that paint. Unfortunately this means that
the viewport will be set again once the ConfigureNotify is received
but compared to rendering an initial invalid scene I think it is the
lesser of two evils.

171a7647b9 Bug 1395 - apply and get_nth_actor are inconsistent
When calling clutter_behaviour_apply() the new actor is prepended
to the list of actors to which a behaviour is applied; this breaks
the rest of methods working on the actors list, e.g.:

  # adding actors
  apply(actor_0);
  apply(actor_1);
  apply(actor_2);

  # expected: [ actor_0, actor_1, actor_2 ]
  [ actor_2, actor_1, actor_0 ] = get_actors();

  # expected: actor_2
  actor_0 = get_nth_actor(2);

This commit fixes the inconsistency in the returned values.

ba068f6bc9 Fix the Cogl primitives for the GLES backend
The Cogl primitives broke for GLES 1.1 and 2 after the cogl-float
branch merge.

CoglPathNode was still being declared as GLfixed for the GLES backend
but it was being filled with float values so they were all ending up
as numbers < 1.

glDrawArrays was being called with GL_FIXED so this has been changed
to GL_FLOAT.

The scanline rasterizer had a leftover hardcoded ClutterFixed constant
to add a small amount to the height of each line.

struct _CoglFloatVec2 has been removed because it is no longer used
anywhere.

4d7caa4bd5 [clutter-timeline] Remove the code for backwards timelines in get_progress
The special check to invert the progress when the timeline direction
is backwards is not necessary because the actual frame number will be
decreasing in that case. Inverting just makes it progress forwards
again.

This is more apparent since the float-alpha-value branch merge because
the clutter_linear function directly returns the value from
get_progress. For example in test-depth, the animations loop instead
of oscillating back and forth.

9ea6ab76fb Fix gtk-doc reference since the anchor point changes

point will move when the actor changes size if it was specified using

d5e5d35316 Convert the rotation centers to be AnchorCoords
Currently only the Z axis rotation center can be set using a gravity
but the other rotations also store their center as an AnchorCoord for
consistency. Specifying the center as a gravity makes less sense for
the other axes because the actors have no size along the Z axis.

The rotation angles are now stored as gdoubles and the fixed point *x
entry points have been removed.

The Z rotation can now be set with a gravity center using the
following new function:

void clutter_actor_set_z_rotation_from_gravity (ClutterActor   *self,
                                                gdouble         angle,
                                                ClutterGravity  gravity);

e10d255b83 Add a scale center property to ClutterActor
This sets the center point from which the scaling will occur. This can
be used insetad of the anchor point to avoid moving the actor. Like
the anchor point, it can be specified as either a coordinate in units
or a gravity enum.

To set the center you can use two new variants of set_scale:

clutter_actor_set_scale_full (ClutterActor *self,
                              gdouble       scale_x,
                              gdouble       scale_y,
                              int           center_x,
                              int           center_y);

or

clutter_actor_set_scale_with_gravity (ClutterActor   *self,
                                      gdouble         scale_x,
                                      gdouble         scale_y,
                                      ClutterGravity  gravity);

The ClutterFixed variants of the set_scale functions have been removed
and the scale value is now always stored as a double.

a24b9a32e5 Store when the anchor point is set from a gravity
This makes it so when the anchor point is set using a gravity enum
then the anchor point moves when the actor changes size. A new
property is added for the anchor point gravity. If the anchor point is
set from gravity then the position in units can also be retreived with
the regular API.

A new union type is used to store the anchor point with helper
accessor functions. The hope is these can be reused for the scale and
rotation center points.

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.
