This blocks the most common methods of webgl/canvas fingerprinting that rely on scripts like https://github.com/Valve/fingerprintjs2/blob/49e2c11cf08c13e12bf38185cec9ae159025e526/fingerprint2.js. The detection method is adapted from https://github.com/EFForg/privacybadgerchrome.
TODOs:
Test case: see the results on https://panopticlick.eff.org/results?#fingerprintTable for fingerprint and webgl before and after this change.
