/*
There seems to be 'UNKNOWN' characters like '\' or '@', which produces error message
Unknown Error: ERROR: 0: ? : '' : syntax error
in the 1st source line of my firefox browser(Win7).
- Who produces that error - the browser, WebGL2 implementation, the graphics card ?
- Why is the error message not appearing in the proper line?
- Where can I get more info about GLSL compiling?
