Bart, I have come to realize that the KeyMapDHTML2 widget is missing a fairly
important capability.  The attribute list includes minx, miny, maxx, maxy and
SRS, but these values are never used in the code.

The problem I fixed before made navigation on the keymap seem to work correctly,
but now I am not entirely sure.  The navigation code does not take into
consideration the extents of the keymap and the SRS of the keymap.

This means that the widget only works correctly when the keymap extents and SRS
match the map's extents ... I believe that it is correctly accomodating aspect
ratio differences, but not geographic differences.

This is a non-trivial amount of work to fix.
