Feature: Rich tooltip

[private-lock]

You already add the hint which mouse button to use to the tooltip.

Could you please add:

• the state of Ctrl configured in the settings
• the original size of the image
• the currently zoomed size if different from the original (either zoomed through this addon or defined in the page)
• the zoom-factor in percent if deviating from 100% (independently for width and height if different)
