you intentionally need double precision, it is ok to leave it as it is.

Changed to floating point constants, thanks.

Implemented the scaling filters using discrete convolution and ported most
of the filters from libswscale.

Some scaling filters implemented as OpenCL kernels. Can be used as:
scale_opencl=::flags=
where can be `neighbor', `bilinear', `bicubic' or `fast_bicubic'
This is an initial draft, there's still a long way to go in terms of
completeness, config
