<?blockprogression>
Description
Indicates the global direction of a block. The columns normally flow left to right, but will flow from right to left if <?blockprogression=1> is set. This means that both data and the column definition will start in the column on the right.
* 
Setting this command does not mean that the text within the cells will flow from right to left. To achieve that effect, the paragraph needs to be drawn from right to left too, via a <?tpdir=1> command in the block preamble.
This command does not change the definitions of left and right — table rule and margin settings are not affected and will be placed in the same location as for a left to right table.
Cell rules also still obey left and right — cell tests for being on the left or right of the table will still be processed correctly although they will now be triggered within different columns.
