/*
INSTRUCTIONS:

1. open chrome, get the dinosaur 'no internet' page happening
2. we need to tell the script where the dinosaur is; we use a highly technical approach -
   putting the mouse just behind the bottom left* of the dinosaur and then pressing enter in LINQPad.
   
   when the first if statement is `if (true)`, the script waits for you to press enter in the readline box and takes
   the current cursor position. so the approach is
        - press play on LINQPad, click inside the readline box
        - move your cursor to the correct position behind the dinosaur
        - press enter
   that mouse position is saved so for as long as you don't move the chrome window you can change `if (true)` to `if (false)`
   and it will keep using the old position. alternatively, experiment with different positions to improve the dinosaur's performance

3. that's pretty much it - once location is set the script will press space when it 'thinks' there's a threat nearby
4. it's not a very smart script

note: doesn't work with font scaling - i guess the dimensions change. some of the nugets/references probably aren't needed

* i 'think' it's the bottom left - if the boundaries around the dinosaur look like this, it is correct: http://i.imgur.com/choOOMU.png
