added new wedge shape.  cleaned up shape comments.  added degToRad and radToDeg helper in Type utility
cleaned up some cropping logic in Image, and added a cropping unit test
optimized line shape drawing logic, and also added image cropping performance tests
wrapped all modules with anonymous func.  moved Canvas to root dir because it's now coupled to KineticJS logic.  removed whitelisting arrays from Global.  Did some prep work for AMD and Node support
setup test for require.js support
changed test to warn for node and shape selector unit test, and added more info in the README Testing section
improved Testing README
adjusted testing subtitle size
Update src/shapes/Sprite.js

Sprites now scale to their width and height correctly in the same way as images
Merge pull request #184 from soulBit/master

Sprites not respecting width and height
changed around the logic from the previous pull, and also added spriteTests to the unit test build
removed unecessary rect draw in sprite scene graph draw func, and changed width and height logic in sprite hit graph draw func
decided to totally revert the pull request.  the frame width and height should be used to define the width and height of the sprite frame, not the shape level width and height.  This is because the frame height and width can change for different frames
fill patterns can now be translated, rotated, scaled, and offset like nodes
added transform property normalization in setFill() method and also added fill transform unit tests
moved dashArray attr to Shape level and hooked into native setLineDash method now that it's in the spec.  This enables dashed lines for any type of stroke, not just straight lines
moved all rendering logic into the Canvas renderer modules.  Shape draw funcs are now passed a renderer object, not a canvas context.  The context is accessible via canvas.getContext()
updated .gitignore and added more performance tests around image cropping and scaling in order to understand the value of a SpriteSheet plugin
fixed several bugs with toImage().  toImage() can now also accept x and y params.  added extensive caching unit test.  removed drawBuffer logic as it is no longer needed
fixed up stage toImage() translation problem
