FlxEmitter rotation problem

[cyberpro4]

I've got some problems with FlxEmitter rotation: I've used some non-square image as particles but during rotation happen two things:

First, the particles was cutted: this was caused by loadRotatedGraphic in makeParticles function: the default AutoBuffer parameter is set to false and there's no way to force it to true via makeParticles() func.

Second, since my bitmap is trasparent I've notice an white solid fill in final rotation bitmap: in FlxSprite::loadRotatedGraphic() the brush variable is constructed with default fill color 0xFFFFFFFF ( solid white ).

At now, I've force these values, but I think this "bug" needs to be fixed.
