The only difference between this and hflp_vulkan.c is a one-line
change in a shader. Could you merge the filters together?
Just add a flag to the init function and filter frame function,
and add separate hflip and vflip filter frame functions which
call the wrapped filter frame function with a different argument.
As for the name, I think vf_flip_vulkan.c would do.
