-				Sets the camera projection to frustum mode (see [constant PROJECTION_FRUSTUM]), by specifying a [param size], an [param offset], and the [param z_near] and [param z_far] clip planes in world space units. See also [member frustum_offset].
+				Sets the camera projection to frustum mode (see [constant PROJECTION_FRUSTUM]), by specifying a [param size], an [param offset], and the [param z_near] and [param z_far] clip planes in world space units. The [param size] parameter represents the size of the near plane, either its width or height depending on the value of [member keep_aspect]. See also [member frustum_offset].
