Bug 1035 - Allow Gamma [Brightness, Contrast] settings to be performed on display/screen of a NativeSurface

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.

Tested manually w/ TestGearsES2NEWT on X11 and Windows
using the 'g' and 'G' to modify gamma.
Value is properly reset on exit.
