Positioning buttons,text, etc. on the world map.

[bsmorgan]

There are various addons that place buttons, checkboxes, text, etc. on the world map border. The objects are correctly positioned when the world map is full screen but incorrectly positioned when the world map is in its partial screen position.

How can an addon correctly position an object on both? How can an addon tell when the map is resized? A pointer to existing code which does the correctly would be great.

Thanks for your help.

Regards,

Brad
