# Attempt to verify that bug673 remains fixed.  This bug is trigger if
# a map is drawn such that the layer->project flag gets set to FALSE (no
# reproject needed), but then a subsequent reset of the layer projection
# and new draw map end up not having the reprojection done because the flag
# is still false.
