examples/gopher/gopher.go couldn't load PNG

[tleyden]

Before fix:

func initScene() (err error) {

    texture, err = createTextureFromBytes(gopher_png[:])
    return
}

Gives compile error:

hornet: gopher$ go run gopher.go
# command-line-arguments
./gopher.go:119: undefined: gopher_png

After fix:

func initScene() (err error) {

    gopher_png, err := ioutil.ReadFile("gopher.png")
    if err != nil {
        panic("Could not load png")
    }

    texture, err = createTextureFromBytes(gopher_png)
    return
}

No, the PNG image is embedded in gopher.png.go.
Please compile/run the full source code with "go build" or "go run gopher.go gopher.png.go".
