Comment 1 Sven Gothel 2014-01-23 05:55:39 CET

NV proprietary driver 331.38 for GNU/Linux contains 
a 32bit libEGL and libGLES* libs.

They seem not to operate w/ an X11 graphics device, only w/ the default EGL device.

Currently we assume a functional driver w/ teh desktop-device,
if the EGL device test was successful.

Hence we shall test whether ES[1-3] is operational on desktop-device.

NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL Device via eglGetDevice.

- Subsequent eglGetDevice(..) calls fail.

- Using the same 'global' egl-device does work though

Remedy: Add 'GLRendererQuirks.SingletonEGLDeviceOnly'

NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL Device 
via eglGetDisplay.

  - Subsequent eglGetDisplay(..) calls fail.

  - Using the same 'global' egl-display does work though

    Detection of quirk is done as usual in GLContextImpl.setRendererQuirks(..),
    and EGLDrawableFactory passes the quirk, if detected, down to EGLDisplayUtil.
    The latter implements the singleton eglDisplay handle.
    
    EGLDisplayUtil: Cleaned up ..
      - EGLDisplayRef employs the reference handling incl. eglInitialize(..) and eglTerminate(),
        as well as the new singleton quirk.
    
      - Mark all internal methods 'private',
        to remove possible [untested] sideffects.

    Refines commit fbe00e6f5dca8043b40dd96f096fecc9424e0cc3
    
    Instead of querying driver artifacts (vendor, platform, version ..)
    we simply can autodetect this quirk by trying to get a second egl-display handle
    when initializing the EGLDrawablFactory's default device:
      EGL.eglGetDisplay(EGL.EGL_DEFAULT_DISPLAY)
