Set this matrix to be an orthographic projection transformation for a right-handed coordinate system.
<p>
This method is equivalent to calling {@link #setOrtho(double, double, double, double, double, double) setOrtho()} with
<code>zNear=-1</code> and <code>zFar=+1</code>.
<p>
In order to apply the orthographic projection to an already existing transformation,
use {@link #ortho2D(double, double, double, double) ortho2D()}.
