Doxygen does not properly form references that span multiple levels,
so instead reword it a bit and manually add the references to what
they should point to.
This filter currently keeps the input timebase, but produces CFR output.
It is thus simpler to use 1/output fps as the output timebase.
Also, set output frame durations.
Fixes the following integer overflows:
libavfilter/vf_rotate.c:273:13: runtime error: signed integer overflow: 92951468 + 2058533568 cannot be represented in type 'int'
libavfilter/vf_rotate.c:273:37: runtime error: signed integer overflow: 39684 * 54149 cannot be represented in type 'int'

libavfilter/vf_rotate.c:272:37: runtime error: signed integer overflow: 42584 * 50430 cannot be represented in type 'int'
libavfilter/vf_rotate.c:272:50: runtime error: signed integer overflow: 65083 * 52912 cannot be represented in type 'int'
libavfilter/vf_rotate.c:273:50: runtime error: signed integer overflow: 65286 * 38044 cannot be represented in type 'int'
Fixes ticket #9799, different output with different compilers.
Apparently this option was intended (the context contains a
currently-unused frame_rate field), but was never added. This results in
the output timebase being unset after config_output(), so the input
audio timebase ends up being used for video output, which is clearly
wrong.
Add an option for setting output video framerate. Also set output frame
durations.
When force_original_aspect_ratio and force_divisible_by are both
used, dimensions are now rounded to the nearest allowed multiple of
force_divisible_by rather than first rounding to the nearest integer and
then rounding in a static direction. This results in less distortion of
the aspect ratio.

Instead of the potentially adjusted ones. Otherwise, if config_props() is
called again and if using force_original_aspect_ratio, the already adjusted
values could be altered again.
Example command line
scale=size=1920x1000:force_original_aspect_ratio=decrease:force_divisible_by=2
user value 1920x1000 -> 1920x798 on init_dict() -> 1918x798 on frame
change when eval_mode == EVAL_MODE_INIT, which after e645a1ddb9 could be at the
very first frame.
