[media] doc-rst: Add new types to media-types.rst 



Changesets:
	eaa0b96b ("[media] media: Add video statistics computation functions")
and
	1179aab1 ("[media] media: Add video processing entity functions")

added some new elements to the "media entity types" table at the
DocBook. We need to do the same at the reST version, in order to
keep it in sync with the DocBook version.

    -  .. row 23



       -  ``MEDIA_ENT_F_PROC_VIDEO_COMPOSER``



       -  Video composer (blender). An entity capable of video

	  composing must have at least two sink pads and one source

	  pad, and composes input video frames onto output video

	  frames. Composition can be performed using alpha blending,

	  color keying, raster operations (ROP), stitching or any other

	  means.

       -  ``MEDIA_ENT_F_PROC_VIDEO_PIXEL_FORMATTER``



       -  Video pixel formatter. An entity capable of pixel formatting

	  must have at least one sink pad and one source pad. Read

	  pixel formatters read pixels from memory and perform a subset

	  of unpacking, cropping, color keying, alpha multiplication

	  and pixel encoding conversion. Write pixel formatters perform

	  a subset of dithering, pixel encoding conversion and packing

	  and write pixels to memory.

       -  ``MEDIA_ENT_F_PROC_VIDEO_PIXEL_ENC_CONV``



       -  Video pixel encoding converter. An entity capable of pixel

	  enconding conversion must have at least one sink pad and one

	  source pad, and convert the encoding of pixels received on

	  its sink pad(s) to a different encoding output on its source

	  pad(s). Pixel encoding conversion includes but isn't limited

	  to RGB to/from HSV, RGB to/from YUV and CFA (Bayer) to RGB

	  conversions.

       -  ``MEDIA_ENT_F_PROC_VIDEO_LUT``



       -  Video look-up table. An entity capable of video lookup table

	  processing must have one sink pad and one source pad. It uses

	  the values of the pixels received on its sink pad to look up

	  entries in internal tables and output them on its source pad.

	  The lookup processing can be performed on all components

	  separately or combine them for multi-dimensional table

	  lookups.



    -  ..  row 27



       -  ``MEDIA_ENT_F_PROC_VIDEO_SCALER``



       -  Video scaler. An entity capable of video scaling must have

	  at least one sink pad and one source pad, and scale the

	  video frame(s) received on its sink pad(s) to a different

	  resolution output on its source pad(s). The range of

	  supported scaling ratios is entity-specific and can differ

	  between the horizontal and vertical directions (in particular

	  scaling can be supported in one direction only). Binning and

	  skipping are considered as scaling.



    -  ..  row 28



       -  ``MEDIA_ENT_F_PROC_VIDEO_STATISTICS``



       -  Video statistics computation (histogram, 3A, ...). An entity

	  capable of statistics computation must have one sink pad and

	  one source pad. It computes statistics over the frames

	  received on its sink pad and outputs the statistics data on

	  its source pad.
