#7242: zoompan filter variables 'in' and 'on' start at 2, 1 instead of at 0

 '''Summary of the bug''': The video filter '''zoompan''' creates variables
 '''in''' and '''on''' for use in expressions. They are described as the
 "input frame count" and "output frame count" respectively. When
 '''zoompan''' filters the first frame, '''in''' is 2, and '''on''' is 1.
 These are non-intuitive values. I expect them both to be 0 for the first
 frame.

 '''How to reproduce''': Use '''[https://ffmpeg.org/ffmpeg-all.html#zoompan
 zoompan]''' filter, with expressions which examine the '''in''' and
 '''on''' values for each frame.

 Two invocations demonstrate this.  Full invocations below and `-report`
 logs below.

 '''Expected behaviour'''

 I expect '''in''' and '''on''' to have the value 0 when the filter
 operates on the first input frame and generates the first output frame.
 This is consistent with how the '''n''' variable behaves with many other
 video filters, e.g. '''crop''', '''drawtext''', etc.

 When the filter operates on subsequent output frames for a given input
 frame, I expect '''in''' to remain at the same value, and '''on''' to
 increment by 1 for each output frame.

 When the filter operates on the next input frame, I expect both '''in'''
 and '''on''' to increment by 1 relative to their values for the final
 output frame of the previous input frame. '''on''' should not reset to
 zero; the '''zoompan:duration''' variable already has this behaviour.

 I expect the documentation for '''zoompan''''s '''in''' and '''on'''
 variables to be clearer and more consistent with the documentation for the
 '''n''' variable in other video filters, e.g. '''crop'''.  For example:

 '''in''': The number of the input frame, starting from 0. It keeps the
 same value as the filter generates successive output frames for the same
 input frame.
 '''on''': The number of the output frame, starting from 0. It increments
 as the filter generates successive output frames for a given input frame,
 and increments again when the filter moves to first output frame for the
 next input frame.
