I don't know solution

var stage = new PIXI.Container();
//dont forget to change that every resize!
stage.position.y = renderer.height / renderer.resolution;
stage.scale.y = -1;

// you need to flip every texture too! 
var texture = PIXI.Texture.fromImage("myTexture.png");
texture.rotate = 8;

// that stuff isnt changed, code like you did it before
var spr = new PIXI.Sprite(texture);
spr.position.x = 100;
spr.position.y = 100;
stage.addChild(spr);

renderer.render(stage);

 

Dont forget to flip ALL the textures you are using. According to http://pixijs.github.io/examples/index.html?s=demos&f=texture-rotate.js&title=Texture%20Rotate&v=dev it can be done by assigning 8 to texture.rotate.
