Set this matrix to be an asymmetric off-center perspective projection frustum transformation for a left-handed coordinate
system using OpenGL's NDC z range of <code>[-1..+1]</code>.
<p>
The given angles <code>angleLeft</code> and <code>angleRight</code> are the horizontal angles between
the left and right frustum planes, respectively, and a line perpendicular to the near and far frustum planes.
The angles <code>angleDown</code> and <code>angleUp</code> are the vertical angles between
the bottom and top frustum planes, respectively, and a line perpendicular to the near and far frustum planes.
<p>
In order to apply the perspective projection transformation to an existing transformation,
use {@link #perspectiveOffCenterFovLH(double, double, double, double, double, double) perspectiveOffCenterFovLH()}.
@param angleLeft
the horizontal angle between left frustum plane and a line perpendicular to the near/far frustum planes.
For a symmetric frustum, this value is negative.
@param angleRight
the horizontal angle between right frustum plane and a line perpendicular to the near/far frustum planes
@param angleDown
the vertical angle between bottom frustum plane and a line perpendicular to the near/far frustum planes.
For a symmetric frustum, this value is negative.
@param angleUp
the vertical angle between top frustum plane and a line perpendicular to the near/far frustum planes
@param zNear
near clipping plane distance. This value must be greater than zero.
If the special value {@link double#POSITIVE_INFINITY} is used, the near clipping plane will be at positive infinity.
In that case, <code>zFar</code> may not also be {@link double#POSITIVE_INFINITY}.
@param zFar
far clipping plane distance. This value must be greater than zero.
If the special value {@link double#POSITIVE_INFINITY} is used, the far clipping plane will be at positive infinity.
In that case, <code>zNear</code> may not also be {@link double#POSITIVE_INFINITY}.
