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.
Fixed as described in commit 15b9e36e80d6f62f7dfb5c45d00cd04de2007ee5
