github noob fix - change from flambe master
roll back entity change in master

confused by git
Added features to Rectangle

- Added top, right, left, bottom
Add Texture.subTexture.

A super handy API (shamelessly borrowed from PlayN) that makes it really
natural to work with sub-regions of a texture atlas.

    var texture = pack.getTexture("Atlas").subTexture(100, 0, 50, 50);
    trace(texture.width == 50); // true

    // Shows only the 50x50 subtexture
    var image = new ImageSprite(texture);

    // Repeats only the subtexture region
    var pattern = new PatternSprite(texture, 100, 100);
Remove BitmapSprite, use subTexture to draw the region instead.

If you were relying on one of the removed BitmapSymbol properties,
switch to using the properties on the SubTexture. eg: bitmap.x is now
bitmap.texture.x, bitmap.atlas is bitmap.texture.parent, etc.
These should be private.
Add Texture.split().
Switch movie frame durations to Float.
Add Library.fromFlipbooks().

Useful for flipbook (spritesheet) animations even if you don't want to
use Flump.
Build fix and hide away some minor implementation details.
Add flambe.util.Pool.
Add explicit return type.
Add Sprite.pointerIn/pointerOut for rollovers.
Hover event tweaks.
Ensure a pointerMove is always emitted before down and up events.
Merge pull request #226 from Jona85/Added-features-to-Rectangle

Added features to Rectangle
Document the new Rectangle fields.
Add Rectangle.centerX/centerY.
Fix completion in some editors, via @markknol.

Mark says this is still a rare issue, but for now close #216 and
close #220.
Implement stage.lockOrientation() in HTML.

Not implemented in most browsers, but coming soon to Chrome and IE
mobile. Note that you have to be in fullscreen first.

Also should work in Firefox, but fullscreen on mobile is awkward:
