47     interpolation qualifiers that are available for fragment shader inputs:
49     interpolation should be used. This is mandatory for integer-type
50     variables. The 'smooth' qualifier indicates that interpolation should be
53     that interpolation should be performed linearly in screen space.
56     two types of interpolation that most commonly used, there are important
57     use cases for linear (noperspective) interpolation.  In particular, in
59     linear interpolation can result in performance and/or power improvements.
61     The smooth and flat interpolation qualifiers are already supported in
63     interpolation to OpenGL ES.
