For the TRIANGLE_STRIP_ARRAY primitive you must set the stripCounts
with GeometryInfo.setStripCounts(). The stripCounts array is an array
of integers that indicate how many vertices are to be used for each
strip. For example, an array of {5, 4, 6} indicates that there are
three strips of length 5, 4, and 6, and therefore it would expect to
have 15 vertices.
If you are sending in individual triangles that you want to convert to
strips with the stripifier, set the primitive to TRIANGLE_ARRAY and
let the stripifier change it to TRIANGLE_STRIP_ARRAY.
