SWT Update: SWT GLCanvas creates lazy when resource is ready; Create new NewtCanvasSWT allowing to parent NEWT windows natively.

SWT GLCanvas creates lazy when resource is ready
  - Ensures drawable and context are created when size > zero and native visualID is valid.
    The latter is platform dependent.
  - Note that you cannot utilize custom GLCapabilities w/ this one,
    since the configurations is already realized - use NewtCanvasSWT.

Create new NewtCanvasSWT allowing to parent NEWT windows natively:
  - Similar to NewtCanvasAWT
  - Allows attaching / detaching NEWT windows

NewtCanvasAWT: Public setNEWTChild(..) fixed

Added test cases for the above - tested on Linux, OSX and Windows w/ SWT

Note: As usual for OSX, add -XstartOnFirstThread

Details:

- NEWT Display has new method: 'EDTUtil setEDTUtil(EDTUtil)'
  allowing to set a custom event dispatch utility.
  We use this to set our SWTEDTUtil for using NEWT w/ SWT
  complying w/ SWT threading constraints.
