Description Sven Gothel 2014-07-27 23:21:41 CEST
Currently GLDrawableFactoryImpl's gamma settings are performed 
only on the main screen.

Allow passing a NativeSurface, so it's display/screen 
gamma values will be changed.

Further, promote low-level gamma settings to GLDrawableFactory
for direct usage.

Change com.jogamp.opengl.util.Gamma to use a GLDrawable
instead of a GL object to clarify that we use the drawable.

Also add a GLAutoDrawable variant, allowing proper locking 
of its 'upstream-lock' to guarantee atomicity.
