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: view.go
    path of file: ./repos/eggos/drivers/vbe
    
    the code of the file until where you have to start completion: // Package vbe provides access to the VESA VBE framebuffer.
package vbe

import (
	"image"
	"image/draw"
)

// View provides a canvas for offscreen rendering which may be commited to the
// framebuffer.
type View struct {
	// underlying offscreen rendering buffer.
	buffer *image.RGBA
}

// NewView returns a new view for offscreen rendering which may be commited to
// the framebuffer.
func NewView() *View {
	return &View{
		buffer: image.NewRGBA
    
func (v *View) CommitRect(rect image.Rectangle) {
	if fbbuf == nil {
		return
	}
	if v != currentView {
		return
	}

	// let rect in the range of view rect
	rect = v.buffer.Rect.Intersect(rect).Canon()

	bufcopy(buffer, v.buffer.Pix, v.buffer.Stride, rect, func(dst, src []uint8) {
		for i := 0; i < len(dst); i += 4 {
			_ = dst[i+3]
			_ = src[i+3]
			dst[i] = src[i+2]
			dst[i+1] = src[i+1]
			dst[i+2] = src[i]
			dst[i+3] = src[i+3]
		}
	})

	bufcopy(fbbuf, buffer, v.buffer.Stride, rect, func(dst, src []uint8) {
		copy(dst, src)
	})
}
