<h1>Matrix</h1>
<p>An affine transform performs a linear mapping from 2D coordinates
to other 2D coordinates that preserves the "straightness" and
"parallelness" of lines.</p>
<p>Such a coordinate transformation can be represented by a 3 row by 3
column matrix with an implied last row of [ 0 0 1 ]. This matrix
transforms source coordinates (x,y) into destination coordinates (x',y')
by considering them to be a column vector and multiplying the coordinate
vector by the matrix according to the following process:</p>
<pre class="code">
[ x'] [ m00 m01 m02 ] [ x ] [ m00x + m01y + m02 ]
[ y'] = [ m10 m11 m12 ] [ y ] = [ m10x + m11y + m12 ]
[ 1 ] [ 0 0 1 ] [ 1 ] [ 1 ]
</pre>
<p>This class is optimized for speed and minimizes calculations based on its
knowledge of the underlying matrix (as opposed to say simply performing
matrix multiplication).</p>
