Detailed Description

Stores the current texture matrix.

This element stores the current texture matrix - the cumulative transformation applied to subsequent shapes. Because the matrix is cumulative, this class is derived from SoAccumulatedElement. The set() method replaces the current matrix, while all the others (mult(), translateBy(), etc.) multiply into it. Node id's of the nodes that affect the element are accumulated properly.
