Here is a Bug,WebGL run faile?

[Gaubee]

I made a simple experiment to test the the WebGL module support, so to use three.js WebGL library.Very simple example, extracted from the official in the examples folder canvas_lines.html, I'm sure I've been independent of these resource files, and successfully run on top of the Chrome and Opera.But when I packaged these resources files, and use nw.exe compile and run, I do not see the correct results. This is the Bug? If yes, please provide the solution.
By the way, compile the application can not run on other computers above, I mean the ordinary nodejs computer, and some anti-virus software will be prompted to risk.

Canvas draw is OK for three.js, WebGL for three.js is broken now.
