Bug 672 (NewtCanvasSWT): Reuse SWTAccessor.isOS_TYPE ; Impl NW.getLocationOnScreen(..) for X11 and Windows ; Allow unit test to run on all platforms.

- Reuse SWTAccessor.isOS_TYPE (public now)

- Impl NW.getLocationOnScreen(..) for X11 and Windows reusing existing native code

- Allow unit test to run on all platforms.

Note: NewtCanvasSWT unit tests require a 'wait for realized' while SWT dispatching.
Otherwise the 'sash unit test' will fail since realiziation happens later, at least on X11.

Hence extended AWTRobotUtil.waitForRealized(..) to use a 'waitAction'
which is used here w/ special SWT dispatch Runnable.

AWTRobotUtil.waitForRealized(..) operates on time-delta instead of iteration-counter,
allowing above 'waitAction' Runnable.

AWTRobotUtil.waitForRealized(..) removed 2nd 'glad.isRealized()' loop ..
