error in SpriteMaterial

[garamaru]

The function function makeTextSprite(message, opts) {[...]} gives me an error with the newest THREE.js(r80).
Something like "there is no extension for that in the material".
The following should be taken out, to still work properly with newer THREE.js-Versions:

//in the line where this is located:
var spriteMaterial = new THREE.SpriteMaterial({
map: texture//, useScreenCoordinates: false
//just commenting that out did the trick
});

Just in case someone else gets the same error.

Also 1 minor question (I don't know if this should get a separate issue):

Why can't I display "lots" of text with the makeTextSprite-function?
For example a timestamp that looks like this: "day 1, 08:00:00"
Only if I define the context like this: context.fillText(message, 0, fontsize, 256);
Also I needed to use another scaling for the sprite too:
sprite.scale.set(200, 70, 2.0);

It shows me the whole text. Otherwise it is cut off after a few digits.

Any suggestions there?
