Apothecary: FreeImage 3.16.0 Working for iOS/OSX

- Finally fixed it. Tested and Working!!!!
I was able to cmake a Xcode project using an old OGRE engine dependancy generator built for FreeImage 2.8. I swapped in 3.16.0 and was able to use Xcode to fix all the very broken code FreeImage 3.16.0 has.
I've e-mailed the main author of FreeImages with these fixes, but they will do fine for us.
