MaxFeatures (for drawing) support lost at 6.2

The layer MAXFEATURES parameter was a means of limiting the number of features drawn. The parameter also was used for limiting query results- kind of a mess. Things were refactored in 6.2 I believe (TODO: find ticket number) and the drawing support seems to be gone...Look specifically at the lakes in the following maps.
