Complete translucency support (core w/ X11 (only) - tested w/ NEWT)

DefaultGLCapabilitiesChooser:
  - Add penalty for opaque mismatch: dbl-buf > opaq > stencil

GLGraphicsConfigurationFactory:
  - Case no-chooser && has-recommended-idx:
      - Only use recommended index if caps is opaque,
        otherwise use default chooser to validate translucency

NativeWindow Capabilities:
  - transparent default values -> 0

Added NEWT Test: TestTranslucencyNEWT

Added command line translucency/undecorated options for TestGearsES2NEWT
