9389d9755d Add the ability to set the text direction
The direction of the text depends on the locale, and it is the
basic setting needed to enable internationalization of user
interfaces.

This commit allows setting the direction of the PangoContext instance
used by Clutter by using the CLUTTER_TEXT_DIRECTION environment
variable, or by passing the --clutter-text-direction command line
argument. Valid values are:

        ltr     - for left-to-right locales
        rtl     - for right-to-left locales

The default is LTR.

Ideally, this should be a value set by the localization teams on the
PO file, but this step requires some build system surgery to allow
the translation of the Clutter strings.

b4a3944b2b Return the default font name if no font name is set
When calling clutter_backend_get_font_name(), if no default font
name has previously been set, we just set the default and return
a pointer to it - like we do for the font options.

e3785f4f45 Use the default font from the Backend
Instead of storing the default font name and size as a pre-processor
macro, use the newly added ClutterBackend API to retrieve the current
default font from the backend.

7262542155 Store the default font name inside ClutterBackend
The default backend stores some of the global defaults, like the
font options, text resolution, double click settings. It should also
store the default font name, to allow various text-based actors to
share the same settings.

When the font name changes, the ::font-changed signal is emitted,
to allow actors to pick up the change.

977bdcf89b Update the PangoContext on backend changes
When the ClutterBackend notifies of changes in the resolution or
font options, update the PangoContext stored by Clutter's main
context. This allows changing the backend font-related settings at
runtime.

213d8f0e4e Store the PangoContext inside the main context
The PangoContext should be stored once, and inside the main
Clutter context. Each actor for which clutter_actor_get_pango_context()
has been called will hold a reference on the Pango context as well.

This makes it possible to update the text rendering for Clutter
by using only public API.

a865a5d4ea Create the PangoContext of the Text actor
Instead of creating a single, private PangoContext for every

78628edf2f Add a per-actor PangoContext
Rendering text inside an actor is pretty much impossible without
using internal API to create the various pieces like the PangoContext
and the font map.

Each actor should have the ability to create a PangoContext, which
is the only object needed to generate layouts and change the various
Pango settings.

This commit adds a clutter_actor_get_pango_context() function that
creates a PangoContext inside the ClutterActor private data and allows
the creation of PangoLayouts when needed. If the actor already
has a PangoContext, the same instance is returned.

The PangoContext is created only on demand.

b8b8b155c4 Add signals for Backend options
The ClutterBackend instance at the moment lacks the ability to
notify runtime changes of the font options and the resolution.

For this reason, this commit adds a ::resolution-changed and a
::font-changed signals to the Backend class.

The ::resolution-changed signal is emitted when set_resolution()
is called with a different DPI; ::font-changed is emitted when the
cairo_font_options_t* changes from the default.

b021f518c1 Use "" as the default value for the :text property
This follows the convention of GtkLabel/GtkEntry in GTK+ and the old
ClutterEntry.

It makes it easier to use strlen/strcmp etc on the output, since we can
assume that it is always a string.

This commit also updates the test unit for ClutterText to verify that
the clutter_text_get_text() function also returns an empty string when
a ClutterText actor has been created.

4a934c363c Do not include cogl-pango.h multiple times
The clutter-private.h header already includes cogl-pango.h with
the correct inclusion path, because the main context stores a
pointer to the font map.

There is no need for clutter-text.c to include cogl-pango.h
again since it already includes clutter-private.h.

3a6ffe3b7d [build] Replaces use of #include <cairo/cairo.h> with #include <cairo.h>
The cairo pkg-config is crafted such that #include <cairo.h> should be used.
If building with a private build of cairo installed to a custom prefix
<cairo/cairo.h> can cause an un-intended cairo header to be picked up during
compilation due to /usr/include being in the header search path.

4e493d1937 Avoid masking math.h exported variables
Our beloved math.h exports, from bits/mathcalls.h, a bare "y1" symbol.
Apparently, it's unthinkable for code including <math.h> to also declare
arguments or variable named "y0", "y1" and "yn".

Anyway, the quick fix already used elsewhere in Clutter's codebase is
to rename the colliding variables "y_0", "y_1" and "y_n" - and
obviously everything similar to them as well, using the same pattern.

81541e6940 [docs] Parameter naming fixes
The name of the parameter in the header and the one in the gtk-doc
annotation on top of a function must match.

Unfortunately, there is an index() function declared inside strings.h
which makes gcc complain for the "index" argument as soon as we
enable the extra compiler flags we use when distchecking.

Hence, we need to rename "index" to "index_" in the header and in
the source files.

64de0411ea [cairo-texture] Remove the construct only restriction on surface size
It is possible to change the surface size after construction with
clutter_cairo_texture_set_surface_size so it doesn't seem right to
restrict changing the properties.

clutter_cairo_texture_resize_surface_internal is called in a handler
for the notify signal. It is called there rather than directly in the
set_property handler so that changing both properties in a single
g_object_set will only cause one resize. The constructed override is
no longer needed.

resize_surface_internal will now bail out if the size of the surface
is already the right size.

cf5d69139d [texture] Do not mix fixed point and units values

cdb78ec4d2 [units] Do not use fixed point and units interchangeably
Clutter units are, at the moment, implemented as a value in fixed point
notation using the same format as CoglFixed. This is, though, an
implementation detail. For this reason, units should not be treated as
CoglFixed values and should be converted to and from fixed point using
the provided macros.

This commit updates the usage of units and fixed point values in
ClutterActor and rationalises some of the transformation code that
heavily relied on the equivalency between them.

for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.

2bf815131a [clutter-interval] Fix calculation of interval for unsigned types
The patch makes it cast to double before subtracting the original
value from the target value. Otherwise if the target value is less
than the original value then the subtraction will overflow and the
factor will be multiplied by a very large number instead of the
desired interval.

The problem is demonstrable using the border-width property of
ClutterRectangle.

e130e0c9b3 [cairo-texture] Silently discard 0x0 surfaces
The current CairoTexture can be created with a surface size of 0
by 0 pixels, but a warning will be printed.

Worse, the surface can be resized to be 0 by 0 pixels without a
warning. The :surface-width and :surface-height properties accept
a minimum value of 0, and not check is performed on either the
constructor or set_surface_size() parameters to enforce the "greater
than zero" rule.

The correct and consistent behaviour is to allow a 0 by 0 pixels
surface size everywhere; inside surface_resize_internal(), the
current surface will be destroyed and if either :surface-width or
:surface-height are set to 0, the resizing terminates.

Attempting to create a Cairo context from a CairoTexture with
either :surface-width or :surface-height set to 0 will result in
a warning.

This allows:

  - creating a CairoTexture with :surface-width or :surface-height
    set to zero and delaying the surface resize at a later point;
  - resizing the surface to 0 by 0 pixels to destroy the image
    surface used internally;
  - increase the consistency in the usage of CairoTexture.

ff92cc9766 Convert clutter_path_get_position to take a gdouble instead of an alpha value
The gdouble value represents an interval along the path from 0.0 to
1.0. This makes more sense than using an alpha value because paths are
not directly related to ClutterAlphas and the rest of the Clutter API
tends to expose gdouble arguments.

7ebb9ff6b7 Allow selecting with line-start and line-end bindings
Instead of installing the line-start and line-end key bindings
using the bare ClutterBindingPool API, we can use the internal
clutter_text_add_move_binding(), which automatically installs
the same key binding with the Shift modifier mask.

This allows selecting when pressing Shift+Home or Shift+End.

The selection behaviour is still incorrect around the zeroeth
position, with all the text after the first line being selected.

ffb500d3a6 Remove unused page up/down key bindings
Moving the text by a "page" depends on being able to define a

cf9dea7cf6 Print a warning when creating a cairo_t while painting
If you create a Cairo context in the middle of a paint run and then
you destroy it, the CairoTexture will have to upload the contents of
the image surface to the GL pipeline. This usually leads to slow
downs and general performance degradation.

ClutterCairoTexture will warn to the console if Clutter has been
compiled with the debug messages and if create() or create_region()
are called while an actor is in the middle of a paint.

2ca7cb46f9 Use the paint opacity when painting a ClutterText
ClutterText should use the paint opacity for both text and
cursor.

ClutterLabel had the wrong behaviour, as it set the actor's
opacity using the text color's alpha channel, and ClutterEntry
completely disregarded the actor's opacity when painting the
cursor.

This commit harmonizes the ClutterText behaviour to always
use a composition of the actor's paint opacity and the text
and cursor alpha channel values, thus behaving more
consistently with the rest of Clutter.

position - and one of the invariants we inherited from ClutterEntry
is that inserting characters programmatically does not change the
cursor position.

35172a7615 Change the binding propagation when truncating a selection
If a selection has been truncated inside a key binding handler,
we should just return and let the usual key event handler continue.

This fixes the case where we deleted a selection using the Delete
or the Backspace keys.

eae98800d2 Use ClutterBindPool inside ClutterText
ClutterText should use the newly added ClutterBindingPool API to
handle key events, instead of its homegrown code.

This commit removes the action/mapping code and defers the entire
key binding matching to a ClutterBindingPool created inside the
Text class initialization function.

b1c366a143 Add Text::get_chars() implementation and tests
The clutter_text_get_chars() function returns a section of the
contents of the Text actor, delimited by a start and an end position.

This commit adds the implementation for that function and a test
unit that guarantees the offset-to-bytes computations are correct.

fc168a3482 Merge the ClutterLabel properties into ClutterText
ClutterText should have the same properties as ClutterLabel.

While at it, we can finally fix the disconnect between the wrap

from GtkLabel.

The ClutterText:line-wrap property and ClutterText:line-wrap-mode
are mapped to the set_line_wrap(), get_line_wrap() and
set_line_wrap_mode(), get_line_wrap_mode() accessor functions
respectively. This should simplify bindings the Vala ones that
map a property into a method.

The TidyText actor is meant as a replacement for both ClutterLabel

bc6a107ff6 Do not modify parameters in place
When the apply_transform_to_point() and its relative variant
landed in Clutter 0.3, the initial approach was to modify the
passed vertex as an in-out parameter. This was later dropped
in favour of a more consistent out parameter.

Unfortunately, the implementation never changed: both methods
where modifying the passed vertex with the partial results of
the computations.

This commit copies the contents of the "point" ClutterVertex
argument inside a stack variable and, for good measure, constifies
the argument.

Thanks to Thomas Steinacher for catching this in Python.

1ce98c97cf Bug 1280 - clutter_score_append_at_marker lead to segmentation
fault in trunk and incorrect appearance in clutter-0.8

	* clutter/clutter-score.c (start_children_entries): Check whether
	the child timeline is actually attached at a marker before
	comparing whether the marker's name matches the marker
	reached. This fixes a crash that happens when a marker is reached
	on a timeline that also has child timelines attached at the
	end. Thanks to zhangwei for spotting.

eeab42b765 Fixed some trivial compiler warnings
* tests/interactive/test-pixmap.c (create_pixmap): Use a format

39aa5c27b5 A comparison of gl/cogl-texture.c and gles/cogl-texture.c, to reduce
differences and improve maintainability.

	* clutter/cogl/gl/cogl-context.h:
	Adds a CoglTextureGLVertex typedef + texture_vertices and
	texture_vertices_size members to CoglContext for using vertex arrays
	like GLES does

	* clutter/cogl/gl/cogl-context.c:
	Initializes texture_vertices + texture_vertices_size members

	* clutter/cogl/gl/cogl-internal.h:
	Adds COGL_ENABLE_COLOR_ARRAY

	* clutter/cogl/gl/cogl.c:
	Add COGL_ENABLE_COLOR_ARRAY support to cogl_enable

	* clutter/cogl/gles/cogl-context.h:
	Change the CoglTextureGLVertex to use GLfloat for the position
	and texture coord attributes and GLubyte for the color.

	* clutter/cogl/gles/cogl-texture-private.h:
	Adds a wrap_mode member like GL has.

	* clutter/cogl/gl/cogl-texture.c
	* clutter/cogl/gles/cogl-texture.c:
	Improves the comparability of the files, such that the remaining
	differences, better reflect the fundamental differences needed
	between GL and GLES. Notably GL no longer uses glBegin/glEnd for
	submitting vertices, it uses vertex arrays like GLES and this gives
	a small but measurable fps improvement for test-text.

Bug 1014 - Clutter Animation API Improvements

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

	* clutter/clutter-types.h: Add AnimationMode, an enumeration
	for easing functions.

	* clutter/clutter-alpha.[ch]: Add the :mode property to
	control the function bound to an Alpha instance using an
	enumeration value. Also add six new alpha functions:

		- ease-in, ease-out, ease-in-out
		- sine-in, sine-out, sine-in-out

	* clutter/clutter-deprecated.h: Deprecate the #defines for
	the alpha functions. They will be replaced by entries in the
	ClutterAnimationMode.

	* clutter/clutter-interval.[ch]: Add ClutterInterval, an
	object for defining, validating and computing an interval
	between two values.

	* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
	object responsible for animation the properties of a single
	actor along an interval of values. ClutterAnimation memory
	management is automatic. A simple wrapper method for
	ClutterActor is provided:

		clutter_actor_animate()

	which will create, or update, an animation for the passed
	actor.

	* clutter/clutter-debug.h:
	* clutter/clutter-main.c: Add a new 'animation' debug note.

	* clutter/clutter-script.c: Clean up the alpha functions
	whitelist, and add the new functions.

	* doc/reference/clutter/Makefile.am:
	* doc/reference/clutter/clutter-sections.txt: Update the
	API reference.

	* doc/reference/clutter/clutter-animation.xml: Renamed to
	doc/reference/clutter/clutter-animation-tutorial.xml to
	avoid clashes with the ClutterAnimation section.

	* doc/reference/clutter/clutter-docs.sgml: Renamed to
	doc/reference/clutter/clutter-docs.xml, as it was an XML
	file and not a SGML file.

	* tests/Makefile.am:
	* tests/interactive/Makefile.am:
	* tests/interactive/test-animation.c:
	* tests/interactive/test-easing.c: Add two tests for the
	new simple animation API and the easing functions.

3d2a1e2d81 Gets the mesh API working with GLES2
* clutter/cogl/common/cogl-mesh.c:
	Make sure we use the appropriate cogl_wrap_gl* funcs as appropriate

	* clutter/cogl/gles/cogl-gles2-wrapper.c
	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	In our glColorPointer wrapper we needed to mark our color attribute
	as normalized.

	* tests/conform/Makefile.am:
	When creating unit test symlinks we use the -l gtester option to
	list tests, but when using the PVR SDK the test binary also spews
	out some extra info that caused lots of random symlinks to be
	created. We now grep for lines starting with a '/'

	* tests/conform/test-mesh-contiguous.c
	* tests/conform/test-mesh-mutability.c:
	Use cogl_set_source_color instead of directly calling glColor4ub

	normalized values; add functions for allocating, copying and
	freeing CoglColor, for use of language bindings.

	* clutter/cogl/cogl.h.in:
