Picture frame rate constants

Using these constants is recommended when the picture rate is known to match one of them, to ensure that floating point equality comparisons work as expected.

Note that the MSL video APIs currently only deal with non-interlaced frames. For interlaced video, all references to the term "picture" should be considered to refer to complete frames. As such, the term "picture rate" here refers to the frame rate for interlaced video.
