Virtualgeoff Drag and Drop Script - with Callbacks

My own version.

Works with position:fixed, absolute and relative. Added callbacks, constaints, min and max values, and snap to grid. Works in IE (finally).

position: relative;
(no callback)

2
position: relative;
constain-X

3
position: relative;
constain-Y
min, max

4
position: absolute;
minX, maxY

5
position: absolute;
minX, maxX,
minY, maxY

6
position: fixed;
snapX, snapY

7
position: relative;

8

10
