Put EGL specific code to a separate file and create the same functions for EAGL, the Apple's specific EGL implementaton. At this point, the EAGL version wasn't compiled or tested as there isn't any simple documented way to build 1.0 for iOS. This code for the EAGL version is still the 0.10 version, some updates should be made when 1.0 is buildable for iOS.
