  * DrawText
  *
  * The parameters for x and y are expressions containing the following constants and functions:
  *
- * dar
- * input display aspect ratio, it is the same as (w / h) * sar
- *
- * hsub
- * vsub
- * horizontal and vertical chroma subsample values. For example for the pixel format "yuv422p" hsub is 2 and vsub is 1.
- *
- * line_h, lh
- * the height of each text line
- *
- * main_h, h, H
- * the input height
- *
- * main_w, w, W
- * the input width
- *
- * max_glyph_a, ascent
- * the maximum distance from the baseline to the highest/upper grid coordinate used to place a glyph outline point, for all the rendered glyphs. It is a positive value, due to the grid’s orientation with the Y axis upwards.
- *
- * max_glyph_d, descent
- * the maximum distance from the baseline to the lowest grid coordinate used to place a glyph outline point, for all the rendered glyphs. This is a negative value, due to the grid’s orientation, with the Y axis upwards.
- *
- * max_glyph_h
- * maximum glyph height, that is the maximum height for all the glyphs contained in the rendered text, it is equivalent to ascent - descent.
- *
- * max_glyph_w
- * maximum glyph width, that is the maximum width for all the glyphs contained in the rendered text
- *
- * n
- * the number of input frame, starting from 0
- *
- * rand(min, max)
- * return a random number included between min and max
- *
- * sar
- * The input sample aspect ratio.
- *
- * t
- * timestamp expressed in seconds, NAN if the input timestamp is unknown
- *
- * text_h, th
- * the height of the rendered text
- *
- * text_w, tw
- * the width of the rendered text
- *
- * x
- * y
- * the x and y offset coordinates where the text is drawn.
- *
- * These parameters allow the x and y expressions to refer to each other, so you can for example specify y=x/dar.
- *
- * pict_type
- * A one character description of the current frame’s picture type.
- *
- * pkt_pos
- * The current packet’s position in the input file or stream (in bytes, from the start of the input). A value of -1 indicates this info is not available.
- *
- * duration
- * The current packet’s duration, in seconds.
- *
- * pkt_size
- * The current packet’s size (in bytes).
