Set this to true when you want your cubemap to appear in world space rather than eye space.
When setUseCameraRotationInverse() is true the texture matrix is computed as:
matrix()*camera->modelingMatrix().as3x3()
This way matrix() represents the transform of the texture in world coordinates, for example if you want to reorient your cubemap in world space or when you want to rotate the direction of one or more highlights prerendered in a cubemap.
