I think you may be misinterpreting that. By "type" there I don't
think it means data type, but rather the "kind" of value, i.e.
coordinates, normal, colour, etc. What it's trying to say is that
the stride is the distance from one entire record to the next.

Not sure about VBOs, but the various predefined formats for
interleaved vertex arrays under the old system certainly include
some with mixed data types.
