test/sanity.js is returning `undefined`

[tmpvar]

There seems to be an issue with the latest binding that causes the following output:

$ node test/sanity.js 
Module included.
enabling GL_LINE_SMOOTH (2848)
ret: undefined
Is GL_LINE_SMOOTH enabled? undefined
Error: undefined
{ reference: true, value: 0.11, type: 'GLfloat' }
delta is now: 10.1

Sanity tests should be ran after a build, and included in a package.json under the scripts.test section

The "undefined" returned means that the c++ function doesn't return nothing. I don't remember it... but if this functions return a boolean variable it will print "undefined". Like you see. But probably the executed functions doesn't return nothing.

My suggestion is to change the actual test file to other much better and funny (:D).

Kisses for everyone!
