Reason: Frame has zoom property, but texture filtering is done automatically and is not configurable.

Solution: texture filtering as additional property for frame, configurable by user. Filter modes should be the OpenGL ones.

    add zoomFilter definition in Frame
    add private Frame::_zoomFilter which set to FILTER_LINEAR by default
    add Frame::setZoomFilter( const ZoomFilter filter )
    add ZoomFilter Frame::getZoomFilter( const ZoomFilter filter )

    add Texture::applyZoomFilter( const ZoomFilter filter )
    glTexParameteri( _target, GL_TEXTURE_MAG_FILTER, _zoomFilter );
    glTexParameteri( _target, GL_TEXTURE_MIN_FILTER, _zoomFilter );

    add Texture::applyWrap() //<! @internal
    glTexParameteri( _target, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE );
