Continuation of the fix in commit 00a3c69868.
Instead of using a separate flag for the resize process, just
delay the setting of the CLUTTER_ACTOR_SYNC_MATRICES flag on the
stage to the point when we receive a ConfigureNotify event from
X11.
This commit will break the stage embedding into other toolkits.
There is a race condition when we resize a stage before showing
it on X11.
The race goes like this:
- clutter_init() creates the default stage and realize it, which
will cause a 640x480 Window to be created
- call set_size(800, 600) on the stage will cause the Window to be
resized to 800x600
- call show() on the stage for the first time will cause COGL
to set up an 800 by 600 GL viewport
- the Window will be mapped, which will cause X to notify the
window manager that the Window should be resized to 800x600
- the window manager will approve the resize
- X resizes the drawable to 800x600
To fix the race, we need to defer COGL from setting up the viewport
until we receive a ConfigureNotify event and the X server has resized
the Drawable.
In order to defer the call to cogl_setup_viewport() we add a new
private flag, CLUTTER_STAGE_IN_RESIZE; the flag is checked whenever
we need to change the viewport size along with the SYNC_MATRICES
private flag. Thus, cogl_setup_viewport() will be called only if
SYNC_MATRICES is set and IN_RESIZE is not set.
Some of the read-write properties of ClutterText were missing
an implementation in clutter_text_get_property(), as well as
the :position and :selection-bound properties being wrongly
converted from fixed point to integer, passing through floating
point values.
ClutterUnits should not be used interchangeably as, or with
ClutterFixed values. ClutterUnits should also not be assumed
to be integers.
This commit fixes the last few improper usages of ClutterUnit
values, and adds a CLUTTER_UNITS_FORMAT macro for safely printing
ClutterUnit values with printf().

Instead of limiting the use of ClutterAnimation to ClutterActor
instances, relax the constraint to include all GObject classes.
ClutterAnimation is not using actor-specific API, since it is
only using properties.
The only actor-based API is the clutter_actor_animate() family
of functions.
ClutterAnimation should check if the object is implementing the
Animatable interface, and if so delegate to it the computation
of the value along the interval initial and final value, depending
on the progress.
The ClutterAnimatable interface is meant to be used by GObject
classes to override the value computation for an animatable
property within the boundaries of an interval.
It is composed of a single virtual function, animate_property();
its implementation will receive the ClutterAnimation used to
animate the object; the property name; the initial and final
interval values; and the progress factor as retrieved by the
Alpha object bound to the Animation instance.
The CoglAngle type can still be used for focused optimisations since the type
and macros remain. Uses of CoglAngle within Cogl have been replaced with floats;
COGL_ANGLE_FROM_DEG is no longer used anywhere and the replacements for
cogl_angle_cos -> cosf (same for sin) have been fixed to convert float values
in degrees to radians. This fixes the cogl-primitives API.
A ClutterInterval can change the way the progress is computed
by subclassing and overriding the ::compute_value() virtual function.
It should also be possible to register a custom progress function
in the same way it is possible to register a custom transformation
function between two GValues.
This commit adds an internal, global hash table that maintains a
GType <-> progress function association; each ClutterInterval
will check if there is a progress function registered for the
GType of the initial and final values of the interval and, if
it has been found, it will call it to compute the value of the
interval depending on the progress factor.
If the computation of the interval value depending on the progress
was not successful, ClutterInterval::compute_value() should return
this information to the caller.
Bug 1289 - Draw multiple glyphs at once
The multiple-texture-rectangle branch adds a new Cogl texture function
called cogl_texture_multiple_rectangles which is used to draw multiple
rectangles out of a texture using a single GL call. This is
significantly faster than drawing the rectangles with individual calls
on some platforms. The Pango renderer now uses this to speed up
rendering.
The conflicts are just due to the whitespace fixes in cb569a5.
Conflicts:

An editable ClutterText should not use pango_layout_set_markup(),
as the contents of the text actor will not match the text.
Only read-only text actors should parse the contents for Pango
markup.
If the Text actor is neither editable nor has its cursor set
to visible, then we should not be ensuring the cursor position.
This fixes a failure in the conformance test unit for the
layout cache.

The cursor should be slightly smaller than the height of the actor, to
allow for painting a border. Let's pad it by 1 pixel on the top and 1
on the bottom.
Also, we should use the cursor size everywhere and not use hardcoded
magic numbers.
Allow using ClutterText as a single line text field. This is useful for
text fields that accept just a single line of contents by default, and
respond to the Enter key press to execute some action.
The :single-line-mode property enables this behaviour inside ClutterText
by clipping and scrolling the contents of the PangoLayout if they do
not fit the allocated width of the Text actor.
When using the delete-prev action from the end of the text we end
up either missing the first glyph we have to delete or falling
through the last one in the text.
This commit fixes both issues.
Since clutter_text_set_text() measures the length of the text
each time, we should use the cached length instead of recomputing
the text length each time. This should save us some time when
dealing with long, multi-byte texts.
It's necissary to replace COGL_FIXED_FROM_INT with a (float) cast otherwise
the replacement maths may end up with integer rounding errors. This was
causing text to not be displayed due to the texture coordinate calculation
always rounding to (0,0)
The previous patch broke some of the normalization done before the sine value
gets multiplied with CLUTTER_ALPHA_MAX. This e.g. broke test-actors when sine
values went through to -1, as the o-hands were scaled so large all you saw was
the red 'O'.
The rest of Cogl expects the texture mode to be GL_MODULATE so it
needs to be restored after calling cogl_material_rectangle. Otherwise
cogl_texture_rectangle will fail to blend with the Cogl color properly
and all of the labels will be black.
Check that the contents of the Text actor are unaffected by the
:password-char property; that the accessors are correct; and finally
that the initial value for a newly constructed Text actor is valid.
Using two properties to set a password entry can be construed as
both cumbersome and a gtk-ism. And rightly so on both counts.
The :text-visible property has also conflicting semantics with the
:cursor-visible one: while the latter hides the cursor, the former
changes the display of the contents of the Text actor. It is, thus,
not a matter of "visibility" but of "rendering".
Instead of setting the :text-visible and :invisible-char properties
to have a password text field, the Text actor should just have a
single :password-char property holding a Unicode character. If the
value of the :password-char is non-zero, the Text actor will use the
Unicode character to render the contents of the text entry.
This commit removes the following methods:
clutter_text_set_text_visible()
clutter_text_get_text_visible()
clutter_text_set_invisible_char()
clutter_text_get_invisible_char()
And the following properties:
ClutterText:text-visible
ClutterText:invisible-char
In favour of:
clutter_text_set_password_char()
clutter_text_get_password_char()
And:
ClutterText:password-char
Thus making obvious what use the property and accessor methods are
for and simplifying the process of creating a simple password text
field to:
text = clutter_text_new ();
clutter_text_set_password_char (CLUTTER_TEXT (text), '*');
The locale translators of Clutter are also the ones that should set
the default direction of the text in a Clutter user interface.
This commit adds a translatable string that defines the direction
of the text; the translation authors will change it to the correct
value and that will determine the default direction.
The default text direction can be overridden by using the
CLUTTER_TEXT_DIRECTION environment variable, or by using the
--clutter-text-direction command line switch. In any other case,
the locale will determine the text direction, as it should.
