OSX Fixes: bug 548 (another regression: pixelfmt), ctx creation failure -> no exception,

- bug 548: Another regression: pixelfmt failed for 10.6.7 and/or software OpenGL
  - enforcing accelerated leads to no pixelformat,
  - using the NSOpenGLView defaultPixelFormat causes to SIGSEGV

- ctx creation failure shall just lead to return null, no immediate exception
