  Bugfixes

libavg 1.7.0.pre1 - Oct 29, 2011

  svn revision 6871

  Major New Features:
    * Expanded effects support: New HueSatFXNode and InvertFXNode by Richard Klemm, major
      speed improvements.
    * Polished multitouch gesture support.
    * New Contact class that delivers per-touch data, per-touch callbacks that make
      event handling a lot easier.
    * SVG support.
    * New BitmapManager that allows loading of bitmaps in a background thread (OXullo
      Intersecans).

  Other Changes:
    * Lots of performance optimizations.
    * Linux ATI graphics are supported now.
    * Major speed improvements to VideoWriter. Saving full HD videos is not a problem
      anymore and costs little performance for the main rendering thread.
    * Callbacks don't hold references to python objects anymore - this should make
      freeing nodes a lot easier.
    * New StateMachine class.
    * Added Player.getPixelsPerMM(), getPhysicalScreenDimensions(), assumePixelsPerMM()
    * Added touch feedback class.

      XInput 2.1 and LibMTDev. Drivers are autodetected if possible.
    * (Finally!) Added clean windows build files for VS 2010 to the open source 
      distribution.

  Other Changes:
    * (Finally!) Found an invisible workaround for the Linux/Mesa graphics segfault
      that's been plaguing us for years (Chase Douglas).

    * libavg can be built with binutils-gold under linux.
    * Intelligent fallback for multisampling.
    * FXNodes can now change the size of the node - necessary e.g. for blur and shadow.
    * Added Player.getTimeSinceLastFrame().
    * Added avg_checkvsync.py utility.

    * Multitouch emulation module added to AVGMTApp.
    * masks now work with words nodes.
    * Added video.volume property and video.hasAudio() method.

      it a lot easier to avoid memory leaks. 
    * Lots of bug fixes:
      - Windows gamma is now reset correctly on program end.
      - Linux vsync now much more stable.
      - Setting node.pos.x now throws an error instead of being ignored. 
        Same for all other Point2D attributes.

  svn revision 4100

  Major new features:

    * Support for vector node types: Line, PolyLine, Curve, Circle, Polygon,
      Rectangle. Vector nodes can be textured, with the closed vectors taking two
      textures: one for the outline, one for the fill. Vector drawing is GPU-based.
    * Plugin support. Plugins written in C++ can define complete new node types.
    * Powerful (but still experimental) new animation framework.
    * Unified & much more stable camera drivers. Consistent support for all 
      resolutions & framerates we could test. Support for more than one camera on all
      platforms. fw800 is supported.
    * Uniform support for aggregate types in node interfaces (node.pos, node.pivot, 
      ...)

  Other improvements:
    * gcc 4.4 and ffmpeg 0.5.0 compatibility.
    * Added letterspacing support to words node.
    * Threaded videos are now the default.
    * Improved video seek and loop performance.
    * New Node::getElementByPos() method that returns the node at that point on the
      screen.
    * Added avg.svnrevision and avg.svndate properties so the avg version can be 
      queried.
    * New avg_showfont.py utility to help font selection.
    * New avg_showcamera.py utility to help camera setup.
    * New avg.getMemoryUsage function that returns the resident set size.
    * New Words.addFontDir().
    * Added support for mipmapping node textures, including videos.
    * rasternode.maskhref to support static alpha masks for any videos, word nodes,
      etc.

  Syntax and semantic changes:
    * In the course of adding aggregate types for node attributes, several attributes
      have changed:
      - words.size is now called words.fontsize.
      - pivotx and pivoty have been replaced by pivot.
    * right-aligned and centered words nodes are positioned differently.
    * avgtrackerrc syntax has changed significantly; see src/avgtrackerrc.minimal.
    * Support for firewire cameras using libdc1394 ver. 1 has been phased out. Please 
      install ver. 2.x.
    * The old python-based anim framework is marked deprecated. You need to explicitly
      use the namespace anim to access it.
