Creates a perspective projection matrix with the given (x) FOV, aspect, near and far planes

@param fov The field of view in the x direction
@param aspect The aspect ratio, usually width/height
@param near The near plane, cannot be 0
@param far the far plane, far cannot equal near
@return A perspective projection matrix built from the given values
Creates a perspective projection matrix with the given ( x ) FOV aspect near and far planes
