* Sharing the VBO of 3 GearsES2 instances, each in their own SWT GLCanvas.

* This is achieved by using the 1st GLCanvas as the <i>master</i>
* and using the build-in blocking mechanism to postpone creation
* of the 2nd and 3rd GLCanvas until the 1st GLCanvas's GLContext becomes created.
* </p>

* Above method allows random creation of the 1st GLCanvas <b>in theory</b>, which triggers
* creation of the <i>dependent</i> other GLCanvas sharing it's GLContext.<br>
* However, since this test may perform on the <i>main thread</i> we have
* to initialize all in order, since otherwise the <i>test main thread</i>
