+ * redraws twice, something we call "double refreshes", so we must be
+ * able to identify which events have been already sent to our clients.
+ *
+ * Here is how the algorithm is working:
+ *
+ * - We collect the exposures that the agent sent to its clients in a
+ * region (the "local-region") and store the region for a given win-
+ * dow in a vector.
+ *
+ * - Another region collects the expose that were received from the
+ * real X server (the "remote-region") for the same window.
+ *
+ * - We create a "fake" off-screen window. For every generated region
+ * we send a ConfigureWindow request for that window to synchronize
+ * ourselves with both the remote X server and/or the window manager.
+ *
+ * - When the ConfigureNotify is received, we calculate the difference
+ * between the "remote-region" and the "local-region" for the window
+ * that had collected exposures.
+ *
+ * - Finally we send the resulting exposures to our clients.
+ *
+ * As you may have guessed, the windows are synchronized per-region,
+ * that is there is a single region for a set of exposures. The regions
+ * are handled in order. This means that we can always calculate the
+ * final region by referring to the first element of the vector.
