// 1. to use hover over the image(container) to view a popup of the target image
// 2. to zoom in/out use wheel up/down. to reset press the scroll button
// 3. click left mouse to lock popup this will make it move along with the mouse, click again to release (indicated by green border)
// 4. while being locked the wheel up/down will act as scroll up/down
// 5. double click will lock it on screen preventing it from being hidden
// 6. while locked at screen (indicated by red outline) a single click with the blurred background will unblur it, only one popup per time, so the locked popup will prevent other popup to spawn
// 7. double clicking on blurred background will de-spawn popup
// 8. to turn on/off hover at the bottom of the page

// Configuration ----------------------------------------------------------
// Define regexp of web page you want HoverZoomMinus to run with,
// 1st array value - default status at start of page: '1' for on, '0' for off
// 2nd array value - spawn position for popup: 'center' for center of screen, '' for cursor position
// 3rd array value - allowed interval for spawning popup; i.e. when exited on popup but immediately touches an img container thus making it "blink spawn blink spawn", experiment it with the right number
