ARB programs wishing to use this added functionality need only add: OPTION NV_fragment_program2; to the beginning of their fragment programs. New functionality provided by this extension, above and beyond that already provided by the NV_fragment_program_option extension, includes: * structured branching support, including data-dependent IF tests, loops supporting a fixed number of iterations, and a data-dependent loop exit instruction (BRK), * subroutine calls, * instructions to perform vector normalization, divide vector components by a scalar, and perform two-component dot products (with or without a scalar add), * an instruction to perform a texture lookup with an explicit LOD, * a loop index register for indirect access into the texture coordinate attribute array, and * a facing attribute that indicates whether the fragment is generated from a front- or back-facing primitive.
