vtkOpenGLVideoFrame: Implement display capture in YUV, NV12
- The OpenGL video frame can now capture screen contents in a format that is native to video encoders - nv12, yuv420
- Conversion from RGBA -> down-sampled YCbCr 4:2:0 happens in the respective OpenGL fragment shaders.
- Cleaned up other shaders.
- Add new test data for the NV12 format spinning cylinder.
- Modify moving color bars bitstream.
