1757 * When a modal dialog is shown, all its blocked windows are lined up into
1758 * a chain in such a way that each window is a transient_for window for
1759 * the next one. That allows us to keep the modal dialog above all its
1760 * blocked windows (even if there are some another modal dialogs between
1761 * them).
1762 * This method adds this top-level window to the chain of the given modal
1763 * dialog. To keep the current relative z-order, we should use the
1764 * XQueryTree to find the place to insert this window to. As each window
1765 * can be blocked by only one modal dialog (such checks are performed in
1766 * shared code), both this and blockerPeer are on the top of their chains
1767 * (chains may be empty).
1768 * If this window is a modal dialog and has its own chain, these chains are
1769 * merged according to the current z-order (XQueryTree is used again).
1770 * Below are some simple examples (z-order is from left to right, -- is
1771 * modal blocking).
1772 *
1773 * Example 0:
1774 * T (current chain of this, no windows are blocked by this)
1775 * W1---B (current chain of blockerPeer, W2 is blocked by blockerPeer)
1776 * Result is:
1777 * W1-T-B (merged chain, all the windows are blocked by blockerPeer)
1778 *
1779 * Example 1:
1780 * W1-T (current chain of this, W1 is blocked by this)
1781 * W2-B (current chain of blockerPeer, W2 is blocked by blockerPeer)
1782 * Result is:
1783 * W1-T-W2-B (merged chain, all the windows are blocked by blockerPeer)
1784 *
1785 * Example 2:
1786 * W1----T (current chain of this, W1 is blocked by this)
1787 * W2---B (current chain of blockerPeer, W2 is blocked by blockerPeer)
1788 * Result is:
1789 * W1-W2-T-B (merged chain, all the windows are blocked by blockerPeer)

1882 * chain (i. e. all the windows blocked by this one, directly or indirectly),

1889 * B3 is shown and blocks B1 and B2:
1890 * W1-W2-B1-B2-B3 (a single chain after B1.addToTransientFors() and B2.addToTransientFors())
1891 * If we then unblock B1, the state should be:
1892 * W1-B1 (window W1 is blocked by B1)
1893 * W2-B2-B3 (window W2 is blocked by B2 and B2 is blocked by B3)
