Indexed Format
***** ***** *** *
In this format each pixel is represented by an 8 bit index into a 256
entry ARGB palette. It is intended for
:ref: `Video Output Overlays <osd>` only. There are no ioctls to access
the palette, this must be done with ioctls of the Linux framebuffer API.

[media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.
