        We can reproduce this problem. There are four basic cases to consider for
        transparency:

        1. no color-per-vertex, null ColoringAttributes
        2. no color-per-vertex, non-null ColoringAttributes
        3. color-per-vertex without alpha
        4. color-per-vertex with alpha

        For immediate mode, it appears that cases 1, 3 and 4 are broken. Only case two
        works correctly.

        We will look into fixing this for 1.5.0.
