To avoid clashing with all the scripted changes, clutter-fixed.h and
clutter-units.h were manually converted to internally use floats instead of
16.16 fixed numbers.
Note: again no API changes were made in Clutter.
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.
Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
so that applications may still take advantage of fixed point if they
desire for certain optimisations where lower precision may be acceptable.
Note: no API changes were made in Clutter, only in Cogl.
Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.
- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.
- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.
- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.
Bug 1209 - Move fixed point API in 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
one and avoids the dependency of COGL on Clutter's own API.
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-primitives.c:
* clutter/cogl/common/cogl-primitives.h: Update internal usage of
ClutterFixed to CoglFixed.
* clutter/cogl/gl/Makefile.am:
* clutter/cogl/gl/cogl-primitives.c:
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gl/cogl.c: Ditto, in the GL implementation of the
COGL API.
* clutter/cogl/gles/Makefile.am:
* clutter/cogl/gles/cogl-fbo.c:
* clutter/cogl/gles/cogl-gles2-wrapper.c:
* clutter/cogl/gles/cogl-primitives.c:
* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gles/cogl.c: Ditto, in the GLES implementation of
the COGL API.
* clutter/pango/pangoclutter-glyph-cache.c:
* clutter/pango/pangoclutter-glyph-cache.h: Ditto, in the Pango
renderer glyphs cache.
* clutter/clutter-fixed.c:
* clutter/clutter-fixed.h: ClutterFixed and related API becomes
a simple transition API for bindings and public Clutter API.
* clutter/clutter-actor.c:
* clutter/clutter-alpha.c:
* clutter/clutter-backend.c:
* clutter/clutter-behaviour-depth.c:
* clutter/clutter-behaviour-ellipse.c:

* clutter/clutter-behaviour-rotate.c:
* clutter/clutter-behaviour-scale.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-color.c:
* clutter/clutter-entry.c:
* clutter/clutter-stage.c:
* clutter/clutter-texture.c:
* clutter/clutter-timeline.c:
* clutter/clutter-units.h: Move from the internal usage of
ClutterFixed to CoglFixed.
* doc/reference/clutter/clutter-sections.txt:
* doc/reference/cogl/cogl-docs.sgml:
* doc/reference/cogl/cogl-sections.txt: Update the documentation.
* tests/test-cogl-tex-tile.c:
* tests/test-project.c: Fix tests after the API change
* README: Add release notes.
* clutter/clutter-fixed.h:
* clutter/clutter-units.h: Fix the upper and lower boundaries of
ClutterFixed and ClutterUnit types; G_MAXINT16 and G_MININT16
were not enough to describe those values.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gl/cogl.c: The clip planes are now set using the
inverse projection matrix as the modelview matrix so that they can
be specified in screen coordinates.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Added a member to
cache the inverse projection matrix
* clutter/clutter-fixed.h: Added a constant for converting from
radians to degrees.
* clutter/clutter-fixed.c (clutter_atani, clutter_atan2i): Added
fixed-point versions of atan and atan2.
* tests/test-clip.c: Added a test for clipping with various
rotations and depths.
* tests/Makefile.am (noinst_PROGRAMS): Added test-clip
* clutter/clutter-units.h:
* clutter/clutter-fixed.h: Add boundaries for fixed point
and units values.
* doc/reference/clutter-sections.txt: Update the documentation.
* clutter/clutter-fixed.[ch]: Add a ClutterFixed fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding
ClutterFixed values. This allows creating GObject properties
using fixed point values.
* doc/reference/clutter-sections.txt: Document the newly
added API.
* autogen.sh: Clean up a bit
* clutter/clutter-fixed.[ch]:
(clutter_double_to_fixed),
(clutter_double_to_int),
(clutter_double_to_uint): Make these functions public, as they
are expanded by their respective macros. This fixes the errors
from the linker trying to resolve their name.
* clutter/clutter-fixed.c:
* clutter/clutter-fixed.h:
(clutter_sqrti):
Added extra iteration to the Newton-Rapson algorithm for argumens
lesser than 342 to improve precission.
* clutter/Makefile.am:
* clutter/clutter-debug.h:
* clutter/clutter-fixed.h:
* clutter/clutter-main.c:
* clutter/cogl/gles/Makefile.am:
* clutter/cogl/gles/cogl-defines.h:
* clutter/cogl/gles/cogl.c:
* clutter/egl/clutter-backend-egl.c:
* clutter/egl/clutter-backend-egl.h:
* clutter/egl/clutter-stage-egl.c:
* configure.ac:
Populate most stubs for cogl GL/ES implementation.
(against vincent - see http://svn.o-hand.com/repos/misc/ogles)
Add various fixups to EGL backend.
Code builds and runs (on 16bpp) but yet displays much (is close!)
* clutter/pango/pangoclutter-render.c:
comment out some rouge glBegin/end calls.
* clutter/clutter-fixed.h: Remove some inline documentation to
make the header more readable.
* clutter/clutter-behaviour.c: The actors are store inside a
GSList and not in a GList, so change the list operations to
use the right API.
* clutter/clutter-feature.c: Use clutter_vblank_method() to
get the VBlank method name from the environment variable OR
the command line switch.
(clutter_feature_do_init): Move the check on the features
state here, to avoid an expensive function call, and inline
the function.
* clutter/clutter-fixed.c: Fix gtk-doc.
* clutter/clutter-main.c: Add a --clutter-vblank command line
switch controlling the VBlank method to be used: it overrides
the CLUTTER_VBLANK environment variable.
(pre_parse_hook), (clutter_init),
(clutter_init_with_args): Move thread initialisation before
type init, to avoid the warning that comes with newer GLib
versions.
* clutter/clutter-group.h:
* clutter/clutter-group.c: Mark clutter_group_show_all() and
clutter_group_hide_all() as deprecated.
* clutter/clutter-fixed.h:

* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-group.c:
* clutter/clutter-stage.c:
* examples/super-oh.c: (main):
Add scale API and functionality.
Rework group sizing. Now group size requests have no effect
but can be scaled.
