Subject: Fix GLDrawableFactory: Move 'GLContext getOrCreateSharedContext(..)'
 to non public class GLDrawableFactoryImpl.

Michael Weber's test case (commit e7388512b69979d00e5a213a1b166a1b1726ae0c)
pointed me to the flaw in GLDrawableFactory which exposed a non-public method,
ie. 'getOrCreateSharedContext()'.

This lead to the assumption, that the 'shared' drawable/context of the factory is multi purpose
and may be used for application context sharing - which is not the case.

Changed Michael's test case to use a local shared pbuffer based drawable/context
and made the method non-public, where it belongs.
