Thx to Emmanuel Puybaret

Bug 816 (OSX CALayer pos): Fix location on 'inner CALayer' calculation

'inner CALayer' is the outter AWT Window client space (content).

+++

Pseudo-Code:
  p0 = c.locationOnScreen();
  p0 -= c.getOutterComp.getPos();
  p0 -= c.getOutterComp.getInsets();

Where 'locationOnScreen()' is:
 p0 = 0/0;
 while( null != c ) {
   p0 += c.getPos();
 }

JAWTWindow.getLocationOnScreenNonBlocking(..) validated against
AWT's Component.getLocationOnScreen() - OK for all use-cases.
(Validation enabled w/ DEBUG)

All unit tests manually validated on OSX 10.7 w/ jdk7u40.

Bug 816 (OSX CALayer pos): Add detailed description (pseudo code) to JAWTUtil.JAWT_OSX_CALAYER_QUIRK_LAYOUT

Bug 548: GLRendererQuirks.GLFlushBeforeRelease is needed on OSX < 10.7.3 w/ NV GPU [was comparing against 1.7.3 instead 10.7.3] !

Bug 818: Enable new quirk GLSLNonCompliant on OSX < 10.7 w/ NV GPU; GLJPanel: Don't use GLSL flip if quirk GLSLNonCompliant is present.
