Espresso3D Version 0.4 changelog (this is not a definitive list, lots more has changed than this)

New Features
=============
-Multi-texturing:  Added ability to add up to 2 additional detail textures to objects that will be blended with the main texture.

-Backface Culling: If desired, backface culling can be enabled by calling engine.setBackfaceCullingEnabled(true/false) 

-Sectors have the isLit and setLit properties now.  If lit is set to false, the sector geometry will be fullbright.

-Added ARB_PointSprite sprites that will take effect whenever the video card running the app supports it.  These are MANY times faster
 than legacy sprites
 
-2D and 3D sound support with wavefile loading.  Doppler effect will be available in 0.5.

-Added a logger to the engine that defaults to espresso3d.log.  Engine messages are written here and it is accessible from the engine for 
 your own messages.
 
 

Fixes/Changes (many more things than this were fixed, this is NOT a definitive list)
============================================================================
-E3DTriangle's have been modified to contain E3DTexturedVertex for vertices.  This changed the way actual vertex
 positions are obtained slightly:  Instead of E3DTriangle.getVertexA(), use E3DTriangle.getVertexPosA(), B, C, etc.
 getVertexA will now return an actual vertex object.  This was a necessary step to allow multitexturing.
 
-E3DQuad's had the same changes made as E3DTriangle's detailed above.

-Modified actor file format -  Triangle information goes on a separate line AFTER the triangle definition.  This
 makes it match up exactly to the map file format.  They were inconsistant and I chose to go with the map format.
 
-Improved file loaders - The file loaders didn't cope well with tabs and spacing that wasn't precise to the format,
 this has been improved so spacing and tabbing should be a lot more flexible in the map and actor files.
 
-Collision detection's checkCollision function got a revamp.  This was necessary to make collision detection
 much more powerful.  Collision detectors are now completely independent of each other, so new detectors and
 bounding objects can be added much more easily (before, a detector had to know how to handle every type of
 bounding object/detector.  This is no longer necessary).
 
-Fixed sprite and particle system/particle collision detection problems.

-isActorLit/setActorLit for an actor was renamed to isLit and setLit.  This standardizes it across sectors and actors

-engine.getCollisionDetect has been renamed to getCollisionHandler. This is to remain consistant with names.
  There is now an inputHandler, collisionHandler, and soundHandler sub-systems associated with the engine so
  they should be easier to identify.
  
-Position, left, up, forward vectors are not directly accessed from Actors, sprites, etc, any longer.  You must use
 the orientation object for those (ie: actor.getOrientation().getForward())

-Triangle /Geometry information for objects with getOrientation() methods are now always given in the objects
 local coordinate system NOT in world coordinates.  To get world coords do a theobject.getOrientation().getWorldVector(vec) 
 and theobject.getOrientation().getLocalVector(vec) to convert world coords to an objects local coordinate system.

-Actors are defaulted to Lit not without having to explicitly set it.

-onCollisionDuringUpdate for E3DParticle's was changed to have a boolean return type.  This facilitates being able to ignore a collision for 
 a single particle to keep it moving normally.

-Major speed increases 

-Fixed file loading from a jar problems.  Resources should be located without problems from jars now.
