RFR: 8239589: JavaFX UI will not repaint after reconnecting via Remote Desktop

[Oliver Schmidtmer]

When connecting via Remote Desktop to a Windows 10 machine ans starting a JavaFX application, the D3D pipeline is used
successfully. After closing the the Remote Desktop session and reconnecting, the D3D requests fail with an
D3DERR_DEVICEREMOVED  HResult, and the application contents are not rendered anymore. Reinitializing the whole pipeline
fixes that.
