the test for whether to use hardware tiling. Previously it assumed
that texture coordinates are in increasing order but this is not
the case since bug 1057 was fixed. The texture coordinates are now
sorted later. It also allowed negative coordinates which doesn't
make sense if the texture has waste.
timelines are more than 52 and continue to remove them
* clutter/clutter-score.c (traverse_children): Don't destroy the
entry in the handler for REMOVE_BY_ID. It will be removed again
anyway in the call to g_node_traverse. This was causing a
crash. Thanks to zhangwei for spotting.
`_glDrawRangeElements@24'
Resolve glDrawRangeElements with cogl_get_proc_address instead of
calling it directly because functions defined in GL > 1.1 are not
directly exported under Windows.
* clutter/cogl/common/cogl-mesh.c: Use the function pointer from
the context
* clutter/cogl/gl/cogl-context.c (cogl_create_context): Initialise
function pointer.
* clutter/cogl/gl/cogl-context.h (CoglContext): Add a function
pointer
* clutter/cogl/gl/cogl-defines.h.in: Add a typedef for the
function pointer.
* clutter/cogl/gl/cogl.c (_cogl_features_init): Resolve
glDrawRangeElements
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.
* clutter/clutter-actor.c:
(clutter_actor_set_property): Add sanity checks for NULL
boxed values when setting the rotation center.
* tests/interactive/test-animation.c:
(on_button_press): Add an example on how to use the rotation
properties to animate an actor.
* tests/interactive/test-pixmap.c (create_pixmap): Use a format
string instead of passing the error message directly to g_error.
* tests/interactive/test-easing.c (test_easing_main)
(on_button_press):
* tests/interactive/test-animation.c (on_button_press): Use
unsigned variables for the results from clutter_actor_get_size
otherwise it complains about the pointer signedness being
different.
* clutter/clutter-script.c (clutter_script_add_search_paths): Use
G_GSIZE_FORMAT instead of %d for a gsize parameter otherwise it
gets upset on 64-bit.
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.
* clutter/cogl/cogl-shader.h: Add a function for setting an
integer uniform, similar to cogl_program_uniform_1f().
* clutter/cogl/gl/cogl-program.c: Implement the GL version
of cogl_program_uniform_1i().
* clutter/cogl/gles/cogl-program.c: Implement the GLES version
of cogl_program_uniform_1i().

- 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.

Winkler)
* clutter/clutter-score.c: Emit the ::started signal.
* tests/interactive/test-score.c: Check the emission of the
Score signals.
* clutter/cogl/gles/cogl-gles2-wrapper.c:
Initialise the 'tex' sampler uniform to 0. The GLSL spec
specifically says that you must initialize sampler uniforms. This
fixes texturing for GLES 2 when using the PowerVR simulator via
software Mesa.
* 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
* clutter/clutter-behaviour-ellipse.c:
(clutter_behaviour_ellipse_applied): Do not reset the depth
of the actors to which the Ellipse behaviour has been applied
to, unless the behaviour is going to update it because it has
a tilt on the X or Y axis.
(clutter_actor_get_paint_visibility): Be sure to return exactly
TRUE or FALSE instead of zero or some non-zero value in these
functions that return a gboolean. Thanks to Kai Wei for spotting.
* clutter/cogl/cogl-color.h:
* clutter/cogl/cogl-path.h:
* clutter/cogl/cogl-types.h:
* clutter/cogl/common/cogl-color.c: Deprecated cogl_color()
in favour of cogl_set_source_color() and friends; store the
CoglColor components as unsigned bytes instead of fixed point
normalized values; add functions for allocating, copying and
freeing CoglColor, for use of language bindings.
* clutter/cogl/cogl.h.in:
* clutter/cogl/cogl-deprecated.h: Added cogl-deprecated.h,
an header file containing the deprecation symbols similar
to clutter-deprecated.h.

The Mesh API provides a means for submitting an extensible number of
per vertex attributes to OpenGL in a way that doesn't require format
conversions and so that the data can be mapped into the GPU (in vertex
buffer objects) for - hopefully - fast re-use.
There are a number of things we can potentially use this API for, but
right now this just provides a foundation to build on. Please read
the extensive list of TODO items in cogl-mesh.c for examples.
Please refer to the cogl-mesh section in the reference manual for
documentation of the API.

Bug 1238 - [PATCH] Pack bitfields in ClutterTexturePrivate
* clutter/clutter-texture.c:
Using 'guint my_field : 1' for booleans to save space only
makes sense if you group all such fields together. Fix
grouping for ClutterTexturePrivate. Thanks to Owen Taylor for
patch.
* clutter/clutter-actor.c:

* clutter/clutter-clone-texture.c:
* clutter/clutter-private.h:
* clutter/clutter-texture.c:
* clutter/x11/clutter-x11-texture-pixmap.c:
Attempt to lower overhead of updating TFP's (particularly mipmaped).
Compresses mipmap updates only for visible TFPs.
Avoiding updates for non visible TFP's whilst keeping visible
clones working ok.
* clutter/clutter-main.c (_clutter_id_to_color): When using fuzzy
picking to pick a color for an actor, it would previously set the
fuzzy bit and then all but the most significant of the remaining
unused bits. This meant that for 16-bit displays it would end up
with a strange pattern for the unused bits like 1011 which could
cause it to round up. Now it just sets all but the most
significant of all of the unused bits giving a pattern like
0111. Thanks to Guy Zadickario for the patch.
* clutter/cogl/common/cogl-fixed.c (cogl_fixed_sin)
(cogl_angle_sin, cogl_angle_tan, cogl_fixed_sqrt): Replaced uses
of 1 + ~x with just -x which is equivalent and easier to
understand.
64-bit multiplication macro instead of COGL_FIXED_FAST_DIV for
calculating xmax as was done previously. This fixes
test-perspective and other tests that had a gone a bit skewiff.
called on complete
* clutter/clutter-score.c (start_children_entries): Use the name
of the marker to start as the data parameter and only start child
timelines that have the same marker name. Previously the
ClutterScore would just start all child entries when a marker was
reached or the timeline completed regardless of whether they were
added with a marker or not. Thanks to Mihail Naydenov for
reporting the bug.
Bug 1231 - Build fails in gles flavour in revision 3442
* clutter/cogl/gles/cogl-context.h: Fix remaining use of
ClutterFixed over CoglFixed. (Michael Boccara)
* clutter/clutter-timeline.c (timeline_timeout_func): Move the
code for firing the new-frame and marker-reached signals into a
separate static function so that it can also be called when the
last frame is reached. Also fix an issue where the frame numbers
were changed in the wrong direction when detecting missed markers
in a reversed timeline. Based on a patch by Michael Boccara.
* tests/test-timeline.c: Now tries to automatically verify whether
the test worked by keeping track of all the signal emissions. The
timelines are run a second time with an extra timeout that causes
delays to simulate skipped frames.
* clutter/clutter-texture.c: (clutter_texture_set_filter_quality),
(clutter_texture_get_filter_quality):
Fix up some logic, typos.
* clutter/glx/clutter-glx-texture-pixmap.c:
Improve support for mipmaped TFP textures.
Bug 1200 - Crash with invalid DISPLAY
* clutter/clutter-main.c: Use the ClutterBackend wrapper API
instead of directly checking the class structure.
* clutter/glx/clutter-backend-glx.c: Return the correct value
in case of failure.

Bug 1211 - Drop ClutterFeatureFlags usage from COGL
* clutter/cogl/cogl.h.in:
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c: Do not use ClutterFeatureFlags
when CoglFeatureFlags will do. This removes the last usage
of Clutter API inside COGL.

* clutter/cogl/cogl-fixed.h:
* clutter/cogl/cogl.h.in:
* clutter/cogl/common/Makefile.am:
* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled
after the ClutterFixed. The CoglFixed API supercedes the ClutterFixed

use the API calls directly instead of loading an extension because
it is part of the core in GLES 2.

COGL_FEATURE_OFFSCREEN.
* clutter/cogl/gles/cogl-fbo.h (CoglFbo): Add gl_stencil_handle.

viewport_store
* tests/test-fbo.c (make_shader): Conditionally use the GLES 2
names of the shader variables
* clutter/clutter-main.c (_clutter_do_pick): After picking is
finished, restore the state of glEnable (GL_DITHER). Otherwise it
will cause the scene to look different after the first pick on low
depth displays. (Thanks to Michael Boccara for the patch)
* clutter/cogl/gl/cogl-texture.c (cogl_texture_polygon)
(_cogl_texture_quad_sw, _cogl_texture_quad_hw):

(_cogl_texture_upload_subregion_to_gl):
When uploading data to a sliced texture, fill the waste pixels
with copies of the edge of the real texture data. Otherwise the
value of the waste pixels are undefined so it will show artifacts
when the texture is scaled with GL_LINEAR and the pixels are
blended in.

* clutter/cogl/gl/cogl-texture.c
(_cogl_texture_upload_subregion_to_gl): When iterating over the
slices, discard ones that don't intersect immediatly otherwise it
will call glTexSubImage2D with a negative width/height and then
move the source position incorrectly. Thanks to Gwenole
Beauchesne.
* clutter/clutter-behaviour-bspline.c: Changed the CBZ_T_POW3 and
CBZ_T_MUL functions so that they preserve more of the least
significant bits. This fixes some of the jaggy behaviour with
longer paths.
reviewed by: Emmanuele Bassi <ebassi@linux.intel.com>
* clutter/clutter-color.[ch]: Add GParamSpec and GValue integration
for ClutterColor. With ClutterParamSpecColor it is possible to define
color properties; with the GValue integration it's possible to
automatically transform strings into colors and vice versa.
(clutter_color_free): Allow NULL parameter to match other boxed
types destructors.
(clutter_color_new): Add a constructor for the ClutterColor boxed
type, mostly for bindings.
* clutter/clutter-container.[ch]: Add checks to the Container
interface invocation methods, to avoid crashing or corrupting
the stack when an actor does not implement every virtual
function of the Container interface vtable. GObject allows this
to happen so we must handle the case gracefully. This also means
that we can classify some virtual function as mandatory (as is
the case for ::add, ::remove and ::foreach) and some other
optional.
Handle dropped motion events when computing crossing events,
based on a patch from Gwenole Beauchesne.
* clutter/clutter-main.c: (clutter_event_get_device): internal static
utility function.
(clutter_do_event): generate enter/leave events for all pointer
events.
(generate_enter_leave_events): modified enter/leave events generator
to work for all pointer event types. Enter/leave events are now
delivered before the motion/button event that caused the crossing to
happen.
* clutter/clutter-event.c: (clutter_event_copy), (clutter_event_free):
removed reference counting logic that is not needed when the crossing
events are directly delivered.
Bug 1130 - CLUTTER_MOTION is not emitted when time goes backwards.
* clutter/clutter-main.c (clutter_do_event): Check for time
rollbacks inside the motion event throttling. (Pierce Liu)
Bug 1154 - clutter_timeout_pool_new() documentation doesn't say
how to free
* clutter/clutter-timeout-pool.c: Update the documentation to
note that you must use g_source_unref() to free the timeout
pool. (Murray Cumming)
Bug 1124 - Clutter causes an additional size request in each
allocation
* clutter/clutter-actor.c:
(clutter_actor_store_old_geometry): Store the allocation instead
of causing a new size-request cycle. (Johan Bilien)
Bug 1125 - Save an extra pango_layout_get_size in many cases
* clutter/clutter-label.c:
(clutter_label_create_layout_no_cache): Add a simple check
before calling pango_layout_get_size(). (Johan Bilien)
* clutter/clutter-alpha.c:
(clutter_alpha_get_alpha): Do not return the cached value but
just compute the current alpha value. The use case is pretty
much straightforward: stop a timeline, advance it, and retrieve
the alpha value before starting the timeline to adjust an
animation dependent on the alpha. Caching the alpha value is
not needed because the behaviours will always pass the alpha
value inside the ::alpha-notify virtual function anyway, so
there is no need for them to call clutter_alpha_get_alpha().
This change makes it also possible to reliably unit-test
ClutterAlpha.
(timeline_new_frame_cb): Call clutter_alpha_get_alpha().
* clutter/clutter-main.c:
* clutter/clutter-main.h:
* clutter/clutter-private.h:
* clutter/x11/clutter-backend-x11.c:
(clutter_get_option_group_without_init):
Function to obtain clutter option group without opening display
(for use with foreign display and gtk_clutter_init). Bug 1033.
Stripped trailing whitespace.
* clutter/clutter-main.c: Don't free the ClutterMainContext so
that the main loop can be restarted.
* clutter/eglx/clutter-backend-egl.c:
* clutter/eglnative/clutter-backend-egl.c: Register an atexit
handler which disposes the backend object so that we are still
guaranteed to call eglTerminate on GLES.
Bug 1033 - Manually parsing command line options prevents
initializing clutter
* clutter/clutter-main.c:
(post_parse_hook), (clutter_init_with_args),
(clutter_parse_args), (clutter_init): Move the initialization
of Clutter at the end of the post-parse hook of Clutter's
GOptionGroup. Clutter must be initialized at the end of the
argument parsing.
* clutter/clutter-main.c: Properly document the
clutter_get_option_group() function and the invariant that
after parsing Clutter's option group the library will be
initialized. (Thanks to Tomas Frydrych for pointing this
out)
* clutter/x11/clutter-backend-x11.c: Properly document the
usage of clutter_x11_set_display().
* clutter/x11/clutter-x11.h: clutter_x11_set_display() is
public API and should be declared in the header we install.
* clutter/cogl/gl/cogl-texture.c (cogl_texture_set_region):
* clutter/cogl/gles/cogl-texture.c (cogl_texture_set_region):
Don't attempt to upload any data if the width or height of the
subregion is zero. Thanks to Gwenole Beauchesne.
* clutter/cogl/gles/cogl.c (cogl_get_viewport): Use glGetIntegerv
instead of glGetFixedv to read the viewport because the latter
converts incorrectly on some hardware.
* clutter/clutter-stage.c (clutter_stage_read_pixels): Use
OpenGL's coordinate system for the arguments to glReadPixels (so
that y zero is the bottom of the window). Use clutter_redraw
instead of clutter_stage_paint to ensure the right GL context is
selected. Set some of the glPixelStore parameters that might have
been changed by Cogl.
* tests/test-stage-read-pixels.c: Replace with a different test
that gets a sub-region of the stage around the cursor.
* clutter/glx/clutter-stage-glx.c (clutter_stage_glx_realize):
Don't set a backing pixel on the X window. Otherwise when the
window resizes it will flicker when X paints the background
immediatly before Clutter repaints the whole stage.
* clutter/clutter-actor.c
(clutter_actor_set_anchor_point_from_gravity)
(clutter_actor_move_anchor_point_from_gravity): Add documentation
to make it clear that the anchor point won't move when the actor
is resized.
window_style correction.
* clutter/win32/clutter-stage-win32.c (get_window_style): Remove
the WS_MAXIMIZEBOX style if the stage isn't resizable.
(clutter_stage_win32_set_user_resize): Queue a redraw of the
window frame when the user_resize property is changed.
* clutter/win32/clutter-event-win32.c (message_translate): Don't
update the size of the stage when handling WM_SIZE messages that
result from the stage being minimized. Thanks to Roman Yazmin.
* clutter/glx/clutter-glx-texture-pixmap.c:
* clutter/x11/clutter-x11-texture-pixmap.c:
TFP resyncing on MapNotify/ConfigureNotify (bug 1020; patch by
Andy Wingo <wingo@pobox.com>).
* clutter/clutter-main.c (_clutter_id_to_color): When choosing a
pick color, set all but the most significant of the unused
bits. This should make make it more likely that the GL
implementation will round down to the right value.
* tests/test-pick.c: Test case for picking. It creates 192 actors
at known positions and stores their gids. It then calls
clutter_stage_get_actor_at_pos with each position to check that
the right gid is returned.
* tests/Makefile.am (noinst_PROGRAMS): Add test-pick
* clutter/clutter-label.c: Bring back layout caching. This time it
will cache up to three different layouts. The width for which each
layout was generated is stored so that if the same width is
requested again it can use the cached version. If no cached
version is available it will try to replace the oldest
layout. 'Age' is determined by a counter which is incremented
every time a layout is created. The cache is cleared after any
property changes that might affect the layout.
(struct _ClutterLabelPrivate): Removed extents_width,
extents_height and context because they weren't used anywhere.
* tests/test-label-cache.c: Add a test which checks whether the
label is using a different layout when properties are
changed. Also compares the extents of the label's layout with an
independent layout and fails if they aren't the same.
* tests/Makefile.am (noinst_PROGRAMS): Add test-label-cache
* clutter/clutter-actor.c (clutter_actor_set_property): When
changing the anchor point properties, use set_anchor_pointu
instead of changing the value directly so that a redraw will be
queued.
(clutter_actor_set_anchor_pointu): Queue a redraw when the anchor
point is changed. Thanks to Johan Bilien.
Bug 1082 - Texture bitmap is destroyed in wrong way
* clutter/cogl/common/cogl-bitmap-pixbuf.c:
(_cogl_bitmap_from_file): Make a copy of the pixbuf data in
the internal image loader so that we can keep working under
the assumption that we are using the GLib memory allocation
and deallocation functions.
