NaNs in 3D fonts?

[greggman]

Description of the problem

This might not be a bug just passing it on.

I added checks for the data passed to bufferData and bufferSubData to the webgl helper I'm working on. If the data is a Float32Array then I check for NaN.

It found some NaNs are being passed for the font geometry in https://threejs.org/examples/webgl_camera_logarithmicdepthbuffer.html.

The NaN values are produces for the last two very large text geometries that have a scale of 1.135e21 and 9.46e23. BufferGeometry.computeVertexNormals() is not able to compute proper normal data and thus produces unusable values.

A simple fix is to remove the last two labels since they are not rendered correctly anyway. I don't think there is a sensible way to fix this in computeVertexNormals().
