| Summary | 0031457: Visualization, TKOpenGl - interface to find an active frame buffer |
| Description | OpenGl_FrameBuffer has a functionality to bind/unbind itself into context.
If we have some buffer in the context before Bind and want to restore it after Unbind, we need to get it. It's proposed to add this interface into OpenGl_Context. |

It is expected introduced API to be used in existing occurrences using GL_FRAMEBUFFER_BINDING as work-around - e.g. VolumeRender and PrsPointCloud packages (OCC Products), which apart from removing workaround would allow testing new patch.
