Introduced in Chapter 9 (on p. 247), this library presents pivoted transformation
operations via the XformInfo class. The D3DDrawHelper class is updated to
support the new XformInfo with the D3D matrix stack.
Figure C.12 highlights the new and updated classes in this library. The fol-
lowing files are modified from the previous version of the library:

9.6, 9.7, 9.8, 9.9,

10.6, 10.7, and 10.8.
