Conversion from ProjectionParametersPerspective.

Parameters

flip has to be used if a gl rendered texture is used but BIAS ProjectionParameters, since up and down interpretation is the other way around (got it?). flip does not have to be true if an BIAS image is uploaded without a previous call to BIAS::ImageBase::Flip(). (However it afterall depends on what you want to achieve!)
