resampleBilinear relX and relY

[savage13]

Should relX and relY in resampleBilinear()
be

    var relX = (inWidth - 1) / (outWidth - 1);
    var relY = (inHeight - 1) / (outHeight - 1);

If the lengths are the same, all is ok
Currently the last interpolated x point is at (outWidth - 1) * (inWidth)/(outWidth)
If inWidth < outWidth then the last point is short of the last input point
If inWidth > outWidth then the last point is beyond the last input point
With this change the last interpolated x point is at (outWidth - 1) * (inWidth-1)/(outWidth-1) is at (inWidth -1)

It is possible that resample*() also requires this change.
