//Diep Units & fov calculator

/* bugs that I need to fix:

- when increasing level while being Tank, circle radius decreases (to ranger size), but tank body increases

  -> possible solution: (complete tanks table, find the fieldFactors here: https://github.com/ABCxFF/diepindepth/blob/main/extras/tankdefs.json)

- window.resize doesn't check if canvas size changes, but only if the user changes it.

For example opening google console changes canvas size, but user didn't change the window.
