Paul B Mahol e917cd9828 avfilter/vf_v360: unbreak fov_from_dfov() for (d)fisheye when width != height 
Based on patch by Daniel Playfair Cal.

Paul B Mahol 1050f94c22 avfilter/vf_v360: allow user to control fov for equirectagular format 
It may be useful to use different values from typical 360/180 deg.

Michael Koch ce8f45aaba 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.

Steven Liu d813e43b3d avfilter/vf_v360: adjustment out_pad and in_pad maximum value to 1/10 
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.
