[BUG] 2D mode not working

Describe the bug
Mizar's 2D mode doesn't work on our version of Mizar and on master one.
It seems to be a polar projection instead.

1. Put the file 'mizar-2d-error.html' in Mizar's examples folder. You can find this file here : mizar-2d-error.zip

2. Open the file 'mizar-2d-error.html' in a browser
