[Fluxus] 0.14b1 on macos

[gabor papp]

distinguishing macos versions could be done in scons using:

if env['PLATFORM'] == 'darwin':
    from platform import mac_ver
    macos_version = mac_ver()[0].split('.')
    env.Append(CCFLAGS = ['-DMACOS_MAJOR_VERSION=' + macos_version[0],
                        '-DMACOS_MINOR_VERSION=' + macos_version[1]])


we could use MACOS_MAJOR_VERSION and MACOS_MINOR_VERSION in
PolyGlyph.cpp to switch between the gluTessCallback calls. these should
be 10 and 4 on tiger and 10 and 5 on leopard. what do you think?
