Commit [r12498] Maximize Restore History

Add doxygen documentation of plcolorbar arguments that were previously

undocumented. This change should finalize the plcolorbar API
documentation in preparation for copying it to the DocBook API
chapter. In addition, this change and a few other minor doxygen
changes eliminated the last of the argument inconsistency warnings
previously generated for pllegend.c by doxygen.
