Bug#959 - Multiple minor improvements
* configure.ac: pick up GDKPIXBUF_PREFIX from gdk-pixbuf-2.0
module, not pango
* clutter/clutter-keysyms-table.h: cosmetic fix for ifdef guard
name in the comment (leftover from earlier commit)
* tests/test-textures.c: don't depend on GdkPixbuf as we're not
using any actual features from it, just plain pixel buffer
manipulation
* clutter/clutter-timeline.c
* clutter/clutter-timeline.h (clutter_timeline_list_markers): Use
gsize* to return number of items, not guint*
* tests/test-paint-wrapper.c: use correct type (guint*) in call
to clutter_actor_get_size()
* tests/test-depth.c (janus_group): properly take height2 into
account when calculating needed height for the rectangle
* tests/test-cogl-tex-getset.c: use rowstride, not width*4, when
calculating pixel offsets
* tests/test-cogl-tex-getset.c: Don't assume/force RGBA format,
also support ARGB format (needed with quartz imageloader.)
clutter_timeline_set_direction instead of static state.
(raise_top): made rectangle remain at fixed depth and raise
above each other.
(janus_group): added a rectangle with two faces, one red and
one green, that spins around.
* clutter/clutter-behaviour-depth.h:
* clutter/clutter-behaviour-depth.c:
(clutter_behaviour_depth_set_bounds),
(clutter_behaviour_depth_get_bounds): Add the depth-start and
depth-end accessors.
* tests/test-depth.c (timeline_completed): Use set_bounds()
instead of g_object_set().
* clutter.symbols: Add clutter_behaviour_depth_set_bounds()
and clutter_behaviour_opacity_get_bounds() to the list of
public symbols.
* clutter/cogl/cogl.h: Add cogl_fog_set() abstracting the
glFog() functions and enabling the GL_FOG flag.
* clutter/cogl/gl/cogl.c: Add GL implementation of cogl_fog_set().
* clutter/cogl/gles/cogl.c: Add GL/ES implementation of
cogl_fog_set().
* clutter.symbols: Add new symbols.
* clutter/clutter-stage.h: Add API to enable depth cueing on
the stage using a linear GL fog, and to set the parameters
for it (#637).
* clutter/clutter-stage.c (clutter_stage_paint): Enable the
GL fog if the ClutterStage:use-fog property is true.
* tests/test-depth.c: Test the new stage API.
* clutter/clutter-behaviour-depth.c:
Modify to work like all other behvaiours in not forcing
increasing order in behaviour 'limits'. (#436)
Rename limit min/max props to start/end.
* tests/test-depth.c:
Simplify test-case to work with above change and
without multiple ramps
* clutter/clutter-behaviour-rotate.c:
Handle CW rotation when end > start and similar for CCW just
like ellipse behaviour.
* clutter/clutter-behaviour-depth.c: Clarify that what drives
the movement along the Z axis is the ClutterAlpha object (we
don't have the luxury of a rollover like the opacity does);
so, if you want to go from 0 to -100 you have to use a
decreasing function, just as well if you want to go from 100
to 0. Using a min-depth of 100 and a max-depth of 0 and an
increasing function is undefined behaviour.
* tests/Makefile.am:
* tests/test-depth.c: Add a test case for the depth behaviour.
