Use this code in DemoFlower::onEnter():
`
ParticleDemo::onEnter();

_emitter = ParticleFlower::create();
_emitter->setEmissionRate(50);
_emitter->setRotation(-30);
_emitter->setAngleVar(0);
_emitter->setAngle(90);
_emitter->setRadialAccel(0);
_emitter->setTangentialAccel(0);
_emitter->retain();
_background->addChild(_emitter, 10);
_emitter->setTexture( Director::getInstance()->getTextureCache()->addImage(s_stars1) );

_background->stopAllActions();

setEmitterPosition();`

Move the particle by mouse/finger, the emitted particle will follow the emitter.

Since we have ParticleSystem::setAngleVar(); and ParticleSystem::setAngleVar(); method, the demand of rotate a ParticleSystem is not that common.
Fix this bug has lots of "transform" work to do, without an inclusive test, add this fix to 3.0 is not safety, and it also has some performance lost.
So I changed this issue to "Candidate for next 3.0 release".
And here is the PR link for someone who urgent need this fix:
