Completing swap-interval implementation for OSX's CALayer usage. Closing Bug 555

- Based on Andres Colubri's initiative and commit 218d67fc0222d7709b21c45792d44501351939c4.

- Reading real screen refresh rate ('stolen' from NEWT)

- Properly handling swap-interval and vsync-to in native code

- Increasing accuracy vsync-to to microseconds

Tested manually w/ TestGearsES2AWT.
