avfilter/vf_v360: fix visibility test for fisheye projection
...
Previously the visibility test referred to a circle in the input. This
changes it so that it refers accurately to the entire area in the input.

avfilter/vf_v360: fix several problems with 'perspective' output
...
The image center wasn't preserved, the output image was mirror reversed,
and rotations were made around wrong axes.
I did also remove the vector normalization, because it's sure that the vector
is already normalized if it's calculated from sin() and cos() terms.

...
Because not every user know about in_pad and out_pad reasonable value range
so maybe try to set 1.0, but setting 1.0 is so hugh to get an fatal error.
