    Experimentally added OpenGL support in window mode (in fullscreen
mode not yet). If you have QNX RtP v6.1.0 w/ or w/o Patch A you  need
to download new Photon3D runtime from http://developers.qnx.com.  The
versions of OS before 6.1.0 is not supported.

Problems:
1. OpenGL support is very raw. It is often fail. Update function has
   not been written yet. Fullscreen mode has not been written yet.
2. Photon has some errors in detecting how much bits per pixel has
   videomode, creating images with different color depth.
3. No shared libraries yet. We need manually set flags as
   --disable-shared.

Some building issues:

    Run configure script without x11 support, e.g.:

    a) for OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared

    a) without OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared    \
                --disable-video-opengl

    In test directory also run ./configure script without x11 support, e.g.:

    ./configure  --with-sdl-prefix=/usr/local      \
                 --with-sdl-exec-prefix=/usr/local \
                 --prefix=/usr/local --without-x
