You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: drawfillover_other.go
    path of file: ./repos/gdlv/vendor/github.com/aarzilli/nucular
    
    the code of the file until where you have to start completion: // +build !amd64 !go1.10

package nucular

import (
	"image"
)

func drawFillOver(dst *image.RGBA, r image.Rectangle, sr, sg, sb, sa uint32) {
	const m = 1<<16 - 1
	// The 0x101 is here for the same reason as in drawRGBA.
	a := (m - sa) * 0x101
	i0 := dst.PixOffset(r.Min.X, r.Min
    
func drawFillOver(dst *image.RGBA, r image.Rectangle, sr, sg, sb, sa uint32) {
	const m = 1<<16 - 1
	// The 0x101 is here for the same reason as in drawRGBA.
	a := (m - sa) * 0x101
	i0 := dst.PixOffset(r.Min.X, r.Min.Y)
	i1 := i0 + r.Dx()*4
	for y := r.Min.Y; y != r.Max.Y; y++ {
		for i := i0; i < i1; i += 4 {
			dr := &dst.Pix[i+0]
			dg := &dst.Pix[i+1]
			db := &dst.Pix[i+2]
			da := &dst.Pix[i+3]

			*dr = uint8((uint32(*dr)*a/m + sr) >> 8)
			*dg = uint8((uint32(*dg)*a/m + sg) >> 8)
			*db = uint8((uint32(*db)*a/m + sb) >> 8)
			*da = uint8((uint32(*da)*a/m + sa) >> 8)
		}
		i0 += dst.Stride
		i1 += dst.Stride
	}
