Texture matrix bug?

[Kesshi]

Currently we have problems to convert our materials to BabylonJs.
The problem is that Texture rotation and scaling is not behaving as expected.

Lets say i have a texture (amiga.jpg in my example) and set the uScale to 10 and the rotation to 30°.
What i expect is this:

What i get with BabylonJs is this: (playground: http://www.babylonjs-playground.com/#1RD35E#3 )

In BabylonJs the rotation is applied first and then the scale. This results in a shearing. I would expect it to be the otherway around.
Is this a bug or the intended behavior? If it is not a bug, would it be possible to set a custom texture matrix on the texture?
At the moment i modify the internally cached texture matrix directly to get what i want but this seems like a hack.

    tex.wAng = BABYLON.Tools.ToRadians(30)/tex.uScale;

@eboo that will not help, the result is not identical to my first picture

it need correct steps order in default fragment shader i think

Correct

You can change the default behavior by overloading texture.getTextureMatrix = function(){

}

So, its not a bug ... its a feature :-)
Ok i will create a derived texture class then and implement a custom getTextureMatrix() function.
Thx.
