Explode no longer handle big buffers

[Fabrice3D]

To reproduce use a mesh with shared vertices right under buffer limit. In this case I use the head model from examples and mirror it to get similar situation
var mesh:Mesh = the head model
//mirroring it to double data and reach the wanted state.
var mirror:Mirror = new Mirror(true, true);
mirror.apply(mesh, Mirror.X_AXIS, Mirror.MIN_BOUND);

        var explode:Explode = new Explode();
        explode.apply(mesh.geometry, false);  --> Error: Error #3670: Buffer too big.

This bug should be fixed by fix #503. It was caused by incorrect LIMIT-Values in "tools/utils/GeomUtil.as"
