示例1: example2

// Since rotation is done around the origin, we must translate
// the point (300,100) up to the origin, do the rotation, and
// then translate back again

// across the x axis, and then rotate everything back again.

// let's say that we want the "logo:" image to be reflected across
// it's own major diagonal. Although we know the logo: image is
// 640x480 let's also generalize the code slightly so that it
// will still work if the name of the input image is changed.
// If the image has a width "w" and height "h", then the angle between
// the x-axis and the major diagonal is atan(h/w) (NOTE that this
