I think this is the only thing I miss from M$ at this point. My mouse
came with some software called inellipoint. It allowed me to click on
the 3rd mouse button (side of the mouse used my thumb) and pull up a
magnifier. Then holding it you could resize the magnifier window and
using the schroll wheel you could zoom in and out. Does anyone use a
similar utility in Ubuntu and do they like?

I finally made exactly what I want, but with "minor bug" I cant
locate.



This code sets initialized viewport as strictBounds with smooth
drag along edges (thanks to SO tip). There is custom zoom-in and
controled zoom-out directed to default(means center of the map at
minZoom) position.



Graphic issue occurs when cursor position on map doesn't change and
I do mouse scroll-in + mouse-out twice in a row. Instead of map zoom,
there is "bugged" image/canvas zoom - double size of markers and
enlarged map canvas bellow - all ofcourse blurred/rasterized. Once I
move with cursor, it redraws and shows properly. Any idea whats wrong?
Thanks!



            /*baseZoom=7,minLevel=7*/
var newLat, newLng,allowedBounds=0,boundLimits,
lastValidCenter,lastZoom,baseCenter;
google.maps.event.addListener(map, 'bounds_changed',
function() {
if (allowedBounds==0) {
allowedBounds = map.getBounds();
/*protoze zobrazovane okno je male, rozsireni
oblasti pro infowindow - pri lepsim zoomu byt nemusi*/

function(e) {

var position = [];position.push(map.getCenter().lat());
position.push(map.getCenter().lng());
position.push(map.getZoom());

var ne = map.getBounds().getNorthEast();
var sw = map.getBounds().getSouthWest();

var pos = [];
pos.push(ne.lat());
pos.push(sw.lat());
pos.push(sw.lng());
pos


.push(ne.lng());



    initialize(flg=3,position,pos);
