Test whether the given XY-plane (at <code>Z = 0</code>) is partly or completely within or outside of the frustum defined by <code>this</code> frustum culler.
The plane is specified via its min and max corner coordinates.
<p>
The algorithm implemented by this method is conservative. This means that in certain circumstances a <i>false positive</i>
can occur, when the method returns <code>true</code> for planes that do not intersect the frustum.
See <a href="http://iquilezles.org/www/articles/frustumcorrect/frustumcorrect.htm">iquilezles.org</a> for an examination of this problem.

@param minX
the x-coordinate of the minimum corner
@param minY
the y-coordinate of the minimum corner
@param maxX
the x-coordinate of the maximum corner
@param maxY
the y-coordinate of the maximum corner
@return <code>true</code> if the XY-plane is completely or partly inside of the frustum; <code>false</code> otherwise
