Started Mac port, so restructuring things to support this. Mac test application somewhat functional.
Added a FilterShowcase example to the Mac port and added an AV Foundation video camera input to the Mac.
Ported several filters to the Mac, along with some base classes. Expanded the FilterShowcase Mac example.
Ported another set of filters to the Mac.
