    DRAW command dversion is improved to report OpenGL variant used (desktop or ES); reporting of version of MSVC is corrected for VC14 and above; reporting of HAVE_OPENCL option is removed.
    
    Usage of command vdump is corrected in some tests to specify extension .png for an image file.
    
    Compiler warning is eliminated in OpenGl_Text.cxx (OpenGL ES mode only).
