Description Sven Gothel 2014-09-20 21:25:27 CEST

Since GLJPanel utilizes offscreen drawable not 
bound to the GLJPanel itself, allow its reconfiguration (recreation)
by changing it's capabilities.

This may help w/ issues, where certain requested caps are not available
and resulting caps are not 'good enough'.

Offscreen's GLCapabilitiesImmutable reconfiguration will dispose a realized instance
and issues recreation via initializeBackendImpl() immedietly.

Implementation performs operation on AWT-EDT.
