public interface LinearTransform extends MathTransform
MathTransform
which convert coordinates using only linear equations.
Such transform can be represented by a matrix.
Those transforms are often affine, but not necessarily.

Matrix getMatrix()
MathTransform
is equivalent to multiplying the
returned matrix by a vector containing the ordinate values with an additional 1 in the last row.
For example if this transform converts projected coordinates (metres) to display coordinates (pixel),
then the same conversions can be done by the returned matrix as below:
