[bw_show_googlemap] shortcode messing up google map controls

[bobbingwide]

In the latest version, the output of the [bw_show_googlemap] shortcode is messing up google maps controls - particularly the zoom slider. This seems to happen regardless of the theme.
The problem is almost exactly as documented here

In a previous version a fix had been provided in oik-css.
The problem was introduced when I added support for multiple googlemaps.
The fix adds a new class ( bw_map_canvas)
which is then styled by the CSS.
.bw_map_canvas { height: 100%; min-height: 100% } .bw_map_canvas img { max-width: none; }
