     * @param name The name of the block used as an identifier.
     * @param insertionPoint Insertion point of the block.
     * @param scaleFactor Scale factor in x / y.
     * @param angle Rotation angle.
     * @param cols Number of cols if we insert a whole array.
     * @param rows Number of rows if we insert a whole array.
     * @param spacing Spacing between rows and cols.
     * @param blockSource Source for the block to insert if other than parent.
     *    Normally blocks are requested from the entity's parent but the
     *    block can also come from another resource. RS_Text uses that
     *    to share the blocks (letters) from a font.
     * @param updateMode RS2::Update will update the insert entity instantly
     *    RS2::NoUpdate will not update the insert. You can update
     *	  it later manually using the update() method. This is 
     *    often the case since you might want to adjust attributes
     *    after creating an insert entity.
