- Camelcased the minified files (it feels weird both ways anyway...)

- Face4 with MeshBitmapMaterial gap fixed

- `three_debug.js` checks for broken UVs and display these faces with pink color instead

* `Face4` now supports `MeshBitmapUVMappingMaterial`
* Changed order of `*StrokeMaterial` parameters. Now it's `color`, `opacity`, `lineWidth`.
* `BitmapUVMappingMaterial` > `MeshBitmapUVMappingMaterial`
* `ColorFillMaterial` > `MeshColorFillMaterial`
* `ColorStrokeMaterial` > `MeshColorStrokeMaterial`
* `FaceColorFillMaterial` > `MeshFaceColorFillMaterial`
* `FaceColorStrokeMaterial` > `MeshFaceColorStrokeMaterial`
* `ColorStrokeMaterial` > `LineColorMaterial`
* `Rectangle.instersects` returned false with rectangles with 0px witdh or height

Old Vector and Matrix constructor functions would create all methods and
make assignments with each call. A lot of speed-ups can be made by using
shared properties through the prototype chain. Since methods and
initialized properties are shared among all instances they're only
created once.

Some tests can be seen at examples/performance-test.html

Some results:

    Chrome

    //6.4 times faster
    performance-test.html:25 Vector2 x 5000000: 213ms
    performance-test.html:30 Vector2Orig x 5000000: 1366ms

    //8.3 times faster
    performance-test.html:37 Vector3 x 5000000: 241ms

    Firefox

    //6.8 times faster
    Vector2 x 50000: 45ms
    Vector2Orig x 50000: 307ms

    //11.5 times faster
    Vector3 x 50000: 48ms
    Vector3Orig x 50000: 550ms

    //3.8 times faster
    Vector4 x 50000: 61ms
    Vector4Orig x 50000: 234ms

    //9.4 times faster
    Matrix4 x 50000: 199ms
    Matrix4Orig x 50000: 1878ms

where "Orig" are old versions of the objects.

Running these tests multiple times can yeild different results due to
browser cache. However the results are always kind of similar in terms
of speedup.

* `Particle` now use `ParticleCircleMaterial` instead of `ColorFillMaterial`
* `Particle.size` > `Particle.scale.x` and `Particle.scale.y`
* `SVGRenderer` currently out of sync

- Seems like new dev version of Blender has some Python API changes. (Can't wait until Blender 2.5 gets released :D)

- Matrix4.lookAt fix (CanvasRenderer and SVGRenderer now handle the -Y)
- Color class now using 0-1 floats instead of 0-255 integers

- Enabled Scene.removeObject
- Removed computeNormals() from Geometry

- Simplified lookAt in Matrix4
- Added cross() in Vector3

- Object3D.overdraw = true to enable CanvasRenderer screen space point expansion hack.

- Fixed overdraw when using stroke materials

* Removed SVG rgba() workaround for WebKit. (WebKit now supports it);
