Can Chrome be used in different zoom levels other than at 100%? - not really

[kensoh]

Raising an issue to update documentation that Chrome needs to be used at 100% zoom.

Otherwise mouse clicks and interactions with web elements will not work. This is because TagUI tries to find the x, y co-ordinates of the web element and trigger a click at that location in Chrome, instead of simply calling methods such as click().

This more accurately re-creates user actions on the webpage and leads to more consistent interactions with websites (by representing a real user more accurately, the website response would be more consistent with how it responses to a real user).

However, with this method, if the Chrome browser is set to a zoom level different from 100%, the x, y co-ordinates to click on will be wrong and thus interactions will not work. Behaviour first observed in #553 while trying to replicate the issue.

Exception will be automating visually. At different zoom levels, as long the UI element image snapshots are done for that particular zoom level, the automation will work correctly.

Added to readme the following note, under the To Use section, right after showing usage of chrome option to run the Yahoo sample with Chrome browser. Copying @ck81 for info, thanks for this!

Make sure TagUI's Chrome browser is set to 100% zoom - as TagUI mimicks the user mouse-clicks at the (x,y) coordinates of web elements, using a different zoom level will cause clicks to be triggered at wrong locations
