Milestone beta3

Goals for this release:

• new rendering features
  • normal (dot3) texture maps (GHOP#335)
  • billboard meshes (GHOP#322)
  • liquid rendering (GHOP#336)
  • sun mesh for lights (GHOP#337)
  • 8 new standard materials (GHOP#320)
• cleaner threading
  • TransportLoop, WindowLoop, SceneLoop = CoreLoop
  • addition and removal from loops standardized
  • replace redundant Children array iterator with standard loop class function
• separate Window classes (#910)
  • soy.Window moved to soy.windows.Window
  • eliminate soy.Screen
  • create Fullscreen and Splash sub-classes to more cleanly implement those options
• audio support
  • implemented via OpenAL 1.1 standard
  • soy.audio akin to soy.textures as buffer container classes
  • add microphone setting properties to soy.bodies.Camera
  • add OpenAL device properties to soy.windows.Window
  • add non-3d music support to soy.widgets.Canvas
  • leave everyone slightly confused by the intuitive audio API
• more scenes
  • soy.Scene moved to soy.scenes.Scene (#903)
  • move physics processing from _coreLoop to Scene (#930)
  • additional scenes to add elements such as plane/heightmap collision (#928 #929)
  • will later offer optimized collision and rendering
• improved controller/action system
  • programmable functions executed in C
  • move EventLoop? to ActionLoop?
  • move python functions as actions into Action, all actions can process Python code
  • controllers provide details about event to actions, such as mouse location, key/button duration, and key/button release
• Video texture improved
  • captured (savable) frame or video of a Window
  • streamed video from a webcam via V4L or directmedia
  • contains an optional .audio object for videos with sound
• better .soy format
  • texture compression via wavelet+rice provides easy mipmapping, progressive loading, smaller file sizes
  • mesh and material support added
• unit tests
  • Mesh vertex/face ordering (GHOP#326)
  • Window creation/destruction, placement, title change
  • Widget stacking, resizing, reparenting
  • Color comparison, math, and hex string
  • Axis rotation

Features this release is unlikely to include:

• Audio capture/compression/playback/streaming
• Network support
• SVG textures
• Native OSX (Carbon) windowing
• Behavior (aka, AI)
• Skeletal mesh deformation
