small 'Quad.set color' optimization (refs #424)
avoiding multiple dispatching of 'addedTo'- and 'removedFromStage' events (closes #426)
new parameter 'transparent' on 'stage.drawToBitmapData' (closes #427)
raised AIR version to 3.9
removed internal closure in 'draw' method to avoid GC issues (closes #417)

Thanks to Jonathan Hart for the fix!
added some information about profile limitations of 'Stage.drawToBitmapData' (refs #427)
'AssetManager.enqueueWithName' now also supports File instances
fixed timing issues when calling 'purgeQueue' and 'loadQueue' in succession (closes #429)
added information about filter disposing (closes #432)
fixed MovieClip docs, contained outdated event info
fixed that ADDED_TO_STAGE event was not dispatched in some situations (closes #437, refs #426)
not calling 'advanceTime' any longer when context is lost (closes #430)

Previously, I only avoided 'render' calls; however, there's also normal user-code that will fail while the context is invalid (e.g. creating a texture). So I shouldn't call any user-code before the context is restored.
now making sure that the correct Starling instance is used when creating assets (closes #433)
now pinning down the starling instance only on 'loadQueue'; added more documentation (refs #433)
fixed wrong method name in API docs
added support for rotated SubTextures (closes #86)
making sure 'mTextBounds' is not null when text field is restored after context loss (closes #453)
added 'rgb' and 'alpha' arguments to 'RenderTexture.clear' (closes #460)
added static 'defaultTextureFormat' property to TextField (closes #461)
