Projection_method projection_method

# DESCRIPTION

This routine converts the chromaticities in the matrix "*input_mp" to RGB
using projection method designated by "projection_method". Not all projection
methods are valid, and sending this routine and invalid one is treated as a
bug. The value ones currently are DIVIDE_BY_RED, DIVIDE_BY_GREEN,
DIVIDE_BY_BLUE, and DIVIDE_BY_SUM.
# DISCLAIMER

This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
