8-bit RLE. This is documented in the MSDN Bitmap Compression page:

The unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.

give very bad quality for soxr resampler.
linear_interp is intended for using linear interpolation

i guess this is misunderstood as 'do not use filter bank,
but directly interpolate linearly between samples'.
