+We are located at 333 West San Carlos Street, Suite 1650, San Jose.
+Our building has a parking garage, and we will validate your parking.
+After you park, as you are walking out of the parking garage, you will
+see a bank of elevators. These elevators only go up and down in the
+garage &#150; they don&#x2019;t connect to the office building. You
+should walk past those elevators, walk out of the garage, walk across a
+courtyard, and into the doors for the main building. There is another
+bank of elevators in that building. Take these elevators to the 16th
+Floor.
+</p>
+
+<p>
+From Highway 280 heading northbound to San Jose: Take the Guadalupe
+Parkway exit, also called Highway 87. This exit splits into a
+northbound and a southbound direction. Take the northbound direction.
+Once on the Guadalupe Parkway take the first exit, which is the Santa
+Clara Street exit. Bear right on Santa Clara Street as you come off
+that exit. The first light you come to is Almaden Blvd. Turn right on
+Almaden. Go down 3 lights to West San Carlos Street. Turn right on
+West San Carlos. The next light you come to is a small street called
+Woz Way. Turn right on Woz. The parking garage for our building is on
+your right. Turn right into the garage. Then follow the directions
+above from the garage to our office.
+</p>
+
+<p>
+From Highway 101 heading southbound to San Jose: Take the Guadalupe
+Parkway exit, also called Highway 87. Stay on the Guadalupe as it
+turns into a surface street and you cross over Hedding and Coleman.
+Once it turns into an expressway again, the second exit is the Park
+Avenue exit. Take this exit. Turn left on Park Avenue. After you
+turn left you will come under the freeway and immediately come to a
+traffic light at a small street called Woz Way. Turn right on Woz
+Way. The parking garage for our building is on your left. Turn left
+into the garage. Then follow the directions above from the garage to
+our office.
+</p>

+From Highway 101 heading northbound to San Jose: Turn on to Highway
+280 headed north. Then follow directions above for Highway 280 heading

+/******************************************************************************************
+ * Before reflow, intrinsic inline-size calculation is done using GetMinISize
+ * and GetPrefISize. This used to be known as pass 1 reflow.
+ *
+ * After the intrinsic isize calculation, the table determines the
+ * column widths using BalanceColumnISizes() and
+ * then reflows each child again with a constrained avail isize. This reflow is
+ * referred to as the pass 2 reflow.
+ *
+ * A special bsize reflow (pass 3 reflow) can occur during an initial or resize
+ * reflow if (a) a row group, row, cell, or a frame inside a cell has a percent
+ * bsize but no computed bsize or (b) in paginated mode, a table has a bsize.
+ * (a) supports percent nested tables contained inside cells whose bsizes aren't
+ * known until after the pass 2 reflow. (b) is necessary because the table
+ * cannot split until after the pass 2 reflow. The mechanics of the special
+ * bsize reflow (variety a) are as follows:
+ *
+ * 1) Each table related frame (table, row group, row, cell) implements
+ * NeedsSpecialReflow() to indicate that it should get the reflow. It does
+ * this when it has a percent bsize but no computed bsize by calling
+ * CheckRequestSpecialBSizeReflow(). This method calls
+ * RequestSpecialBSizeReflow() which calls SetNeedSpecialReflow() on its
+ * ancestors until it reaches the containing table and calls
+ * SetNeedToInitiateSpecialReflow() on it. For percent bsize frames inside
+ * cells, during DidReflow(), the cell's NotifyPercentBSize() is called
+ * (the cell is the reflow input's mPercentBSizeObserver in this case).
+ * NotifyPercentBSize() calls RequestSpecialBSizeReflow().
+ *
+ * XXX (jfkthame) This comment appears to be out of date; it refers to
+ * methods/flags that are no longer present in the code.
+ *
+ * 2) After the pass 2 reflow, if the table's NeedToInitiateSpecialReflow(true)
+ * was called, it will do the special bsize reflow, setting the reflow
+ * input's mFlags.mSpecialBSizeReflow to true and mSpecialHeightInitiator to
+ * itself. It won't do this if IsPrematureSpecialHeightReflow() returns true
+ * because in that case another special bsize reflow will be coming along
+ * with the containing table as the mSpecialHeightInitiator. It is only
+ * relevant to do the reflow when the mSpecialHeightInitiator is the
+ * containing table, because if it is a remote ancestor, then appropriate
+ * bsizes will not be known.
+ *
+ * 3) Since the bsizes of the table, row groups, rows, and cells was determined
+ * during the pass 2 reflow, they return their last desired sizes during the
+ * special bsize reflow. The reflow only permits percent bsize frames inside
+ * the cells to resize based on the cells bsize and that bsize was
+ * determined during the pass 2 reflow.
+ *
+ * So, in the case of deeply nested tables, all of the tables that were told to
+ * initiate a special reflow will do so, but if a table is already in a special
+ * reflow, it won't inititate the reflow until the current initiator is its
+ * containing table. Since these reflows are only received by frames that need
+ * them and they don't cause any rebalancing of tables, the extra overhead is
+ * minimal.
+ *
+ * The type of special reflow that occurs during printing (variety b) follows
+ * the same mechanism except that all frames will receive the reflow even if
+ * they don't really need them.
+ *
+ * Open issues with the special bsize reflow:
+ *
+ * 1) At some point there should be 2 kinds of special bsize reflows because (a)
+ * and (b) above are really quite different. This would avoid unnecessary
+ * reflows during printing.
+ *
+ * 2) When a cell contains frames whose percent bsizes > 100%, there is data
+ * loss (see bug 115245). However, this can also occur if a cell has a fixed
+ * bsize and there is no special bsize reflow.
+ *
+ * XXXldb Special bsize reflow should really be its own method, not
+ * part of nsIFrame::Reflow. It should then call nsIFrame::Reflow on
+ * the contents of the cells to do the necessary block-axis resizing.
