(6.3.1.4  Matrix Keyword)
... the matrix command allows more general transformation effects like 
/shearing/. The following matrix causes an object to be sheared ...

The manual could be changed to make this clearer

6.3.1  Transformations
The supported transformation modifiers are |rotate|, |scale|, 
|translate|, and matrix. They are used to turn, size and move an object 
or texture. A transformation matrix may also be used to specify complex 
transformations directly.

This would clear up the meaning of "may also be used" (for complex 
transformations) instead of (is also supported).
