Added zoom, image, text and eraser

I have been trying your fork, and the zoom-in and zoom-out features work perfectly. Great work on the auto-adjust button as well—it's really convenient.

However, there is an issue with the polygon drawer that is not present in the official version. The zones do not close with the right button, making it almost impossible to draw a zone correctly. (The blue zone is from the official version, the yellow one is my attempt to draw a new one)

Following the above comment, I have been doing some checks and found that the issue is related to the chosen web browser. It causes problems when closing the zones in Firefox; however, it works perfectly on Google Chrome.

Do you get the correct coordinates of the polygon after zooming?

Sorry I’ve only tried on Chrome. Strange issue however as I haven’t touched that tool, I only bumped the fabric js version a little to support the eraser. I do actually have a more updated version, with better text, inserting images etc just not pushed to GitHub yet
