Get auto matrix from swresample

[v0lt]

So I work with avresample:

1. Get auto matrix from avresample - avresample_build_matrix().
2. Analyzing and modifying the matrix.
3. Using matrix - avresample_set_matrix().

I would like also to work with swresample, but I found only avresample_set_matrix() function, but did not find swr_build_matrix(). :(

Swresample generates a matrix using swri_rematrix_init() function. I want the function to access the resulting matrix.

*but I found swr_set_matrix() function only, but did not find swr_build_matrix().
