+** The default lookaside configuration is 100 slots of 1200 bytes each.
+** The larger slot sizes are important for performance, but they waste

+** The two-size-lookaside enhancement breaks up the lookaside allocation

+** follow the range of registers used to construct storage. This
+** avoids computing the same VIRTUAL column multiple times, and provides
+** values for use by OP_Param opcodes in triggers. Hence, if the
+** input column is a VIRTUAL table, put it after all the other columns.
+**
+** In the following, N means "normal column", S means STORED, and

+**
+** CREATE TABLE ex(N,S,V,N,S,V,N,S,V);
+** -- 0 1 2 3 4 5 6 7 8

+**
+** So, in other words, this routine shifts all the virtual columns to
+** the end.
+**
+** If SQLITE_OMIT_GENERATED_COLUMNS then there are no virtual columns and
