Usage: move the mouse to reposition source image.
'1' : zoom in (trails fly out) [default]
'2' : zoom out (trails fly in)
'3' : roto-zoom in (spinning trails fly out)
'4' : roto-zoom out (spinning trails fly in)
'5' : motion blur effect
'6' : wiggle roto-zoom in (wiggly trails fly out)
'7' : wiggle roto-zoom out (wiggly trails fly in)
'8' : wobble roto-zoom in (wobbly trails fly out)
'9' : wobble roto-zoom out (wobbly trails fly in)
'0' : wiggle wobble roto-zoom in (wiggly wobbly trails fly out)

"wiggle" animates the "roto" value - if this were real camera-based feedback
it would be like quickly twisting the camera relative to the screen.

"wobble" animates the "zoom" value - if this were real camera-based feedback
it would be like quickly shaking the camera back-and-forth relative to the screen.
