Detailed Description

Represents a transformation applied to the vertices of an element on the UI. It generates a matrix when applied. This matrix is then applied to any existing matrix (the current top of a stack) and the result is pushed to the same stack. The matrix at the top of the stack is the one which is actually applied to elements.
