B-splines, though mathematically related to Bezier splines, are a
completely different animal, and the b_spline keyword is already used
elsewhere in POV-Ray for... B-splines. To repurpose it for quadratic
Bezier prisms would be confusing on more than one level.
Maybe the keyword "mesh2" is hackish, but for a 2nd degree polynomial,
appending a "2" to "bezier" would be totally appropriate.
