      Remove mentions of the FSF address · 79acb088
      Emmanuele Bassi authored
      Since using addresses that might change is something that finally
      the FSF acknowledge as a plausible scenario (after changing address
      twice), the license blurb in the source files should use the URI
      for getting the license in case the library did not come with it.
      Not that URIs cannot possibly change, but at least it's easier to
      set up a redirection at the same place.
      As a side note: this commit closes the oldes bug in Clutter's bug
      report tool.

      script: Use a node when resolving an animation mode · 09f91ff6
      Emmanuele Bassi authored
      Instead of taking a string and duplicating the "is it a string or an
      integer" check in both Alpha and Animation, the function in
      ClutterScript that resolves the animation mode values should take a
      JsonNode and do all the checks it needs.

      docs: Document the AnimationMode definition · 49cd887a
      Emmanuele Bassi authored
      Both ClutterAlpha:mode and ClutterAnimation:mode can be defined using:
        • an integer id
        • the "nick" field of the AnimationMode GEnumValue
        • a custom, tweener-like string
      All these methods should be documented.

      alpha: Allow setting the function in ClutterScript · f0ed71c7
      Emmanuele Bassi authored
      When defining an Alpha in ClutterScript we should allow setting
      the alpha function by using a custom property. This makes it
      possible to have both:
          "id" : "behaviour-1",
          "type" : "ClutterBehaviourDepth",
          "alpha" : { "timeline" : "timeline-1", "function" : "alpha_func" },

      [timeline] Remove the concept of frames from timelines · 9c7afe0c
      Neil Roberts authored
      Timelines no longer work in terms of a frame rate and a number of
      frames but instead just have a duration in milliseconds. This better
      matches the working of the master clock where if any timelines are
      running it will redraw as fast as possible rather than limiting to the
      lowest rated timeline.
      Most applications will just create animations and expect them to
      finish in a certain amount of time without caring about how many
      frames are drawn. If a frame is going to be drawn it might as well
      update all of the animations to some fraction of the total animation
      rather than rounding to the nearest whole frame.
      The 'frame_num' parameter of the new-frame signal is now 'msecs' which
      is a number of milliseconds progressed along the
      timeline. Applications should use clutter_timeline_get_progress
      instead of the frame number.
      Markers can now only be attached at a time value. The position is
      stored in milliseconds rather than at a frame number.
      test-timeline-smoothness and test-timeline-dup-frames have been
      removed because they no longer make sense.

      [alpha] Sanitize easing equations · d6ccecd7
      Emmanuele Bassi authored
      Bug 1561 - Bad code in clutter-alpha.c
      The implementation of the easing modes equations followed closely
      the JavaScript and ActionScript counterparts. Obviously, JS and AS
      are not C-compatible, so later versions of gcc (4.4.0 for instance)
      would complain about uninitialized variables and such. The code is
      also obfuscated and hard to debug/understand.
      For these reasons, the implementation should be unobfuscated and

      [animation] Implement new easing functions · ec3b1a7b
      Emmanuele Bassi authored
      Instead of using our own homegrown alpha functions, we should
      use the easing functions also shared by other animation frameworks,
      like jQuery and Tween, in the interests of code portability.
      The easing functions have been defined by Robert Penner and
      are divided into three categories:
              In    Out     InOut
      Each category has a particular curve:
      In addition, there are "physical" curves:
              Back (overshooting cubic)
              Bounce (exponentially decaying parabolic)
      Finally, the Linear curve is also provided as a reference.
      The functions are private, and are meant to be used only
      through their logical id as provided by the AnimationMode
      The tests should be updated as well to match the new
      easing functions.

      [animation] Move the alpha value to floating point · 7d7372af
      Emmanuele Bassi authored
      The current Alpha value is an unsigned integer that can be used
      implicitly as a fixed point value. This makes writing an alpha
      function overshooting below and above the current range basically
      impossible without complicating an already complex code, and
      creating weird corner cases.
      For this reason, the Alpha value should be defined as a floating
      point normalized value, spanning a range between 0.0 and 1.0; in
      order to allow overshooting, the valid range is extended one unit
      below and one unit above, thus making it -1.0 .. 2.0.
      This commit updates the various users of the ClutterAlpha API
      and the tests cases.
      This commit also removes all the current alpha functions exposed
      in the public API.

      To deal with all the corner cases that couldn't be scripted a number of patches

      [Automatic fixed-to-float.sh change] Applies all scripted changes · e82f6565
      Robert Bragg authored
      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
      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
      - Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
      angles and math.h replacements.

      [alpha] Allow registering alpha functions · 74213e0e

      In order to unify alpha functions and animation modes in ClutterAlpha
      we should be able to register alpha functions and get a logical id
      for them; the logical id will then be available to be used by
      The registration requires API changes in ClutterAlpha constructors
      and methods. It also provides the chance to shift ClutterAlpha
      towards the use of animations modes only, and to alpha functions
      as a convenience API for language bindings alone.
