Bug 801: Introd. RenderState.BITHINT_GLOBAL_DEPTH_TEST_ENABLED hinting to deal w/ GL_DEPTH_TEST accordingly

Fixes VBORegion2PMSAAES2 no-depth-buffer usage
and allows user to control behavior w/o quering GL state.

If BITHINT_GLOBAL_DEPTH_TEST_ENABLED set:
  - RegionRenderer.defaultBlendEnable:  glDepthMask(false)
  - RegionRenderer.defaultBlendDisable: glDepthMask(true)
  - VBORegion2PMSAAES2 enables/disables GL_DEPTH_TEST, otherwise MSAA is corrupt.
