Fix GLCanvas's JAWTWindow reference ; Add ES2 test in TestAWT01GLn ; Ubuntu 12.04/Pandaboard(Omap4, PowerVR SGX 540) 103/108 tests passed (before freeze) of 124 total

Fix GLCanvas's JAWTWindow reference
  - drawable.getNativeSurface() may not be a JAWTWindow
    due to our EGL WrappedSurface. Hence store the created JAWTWindow reference locally.

Add ES2 test in TestAWT01GLn
  - test EGL/ES2 w/ AWT GLCanvas

Ubuntu 12.04/Pandaboard(Omap4, PowerVR SGX 540): 103/108 tests passed (before freeze) of 124 total
  - machine freezes around test 108 ..
  - new passed unit test high for ES2 incl. AWT tests
