//==================================== Advanced TODO List ========================================================//
/*
//Features that likely wont be implemented due to lack of time and will need to remain for next time
- Rotation by angle (will be possible to implement at later stage in both IE and FF, but it is of little use now, and a lot of work to do properly
*/

//============================ /TEMP Initialization function ======================================================//

	//Integrate code with RadSlider


//==================DONE
/*
	- Mozilla Support!
	- Add move support!
	- Real time values display when resizing
	- Removed the TabStrip - all is now in one pane
	//5. TODO: Convert the Draggable object to an extender or sth
	- Attach onchange handlers to the UI to change the EDITABLE IMAGE
	- Update the current values for the image when switching tabs
	- ImageObject with API that will capsulate the functionality in a transparent manner and hide differences for IE and Moz
	- Detect change in the tab
	- Added reset button
	- Hook all props to a the UI
	- Have the image load in its area
	- Add event to notify parent
	- Add persentages/points (thumbnail creator)
	- Add lock ratio (image props)
	- Suffix property
	- Events on the client
	- MVC archtiecture - parent (ImageManager), child (ImageEditor)
	- Implement a callback function from the AJAX, notify the parent image dialog. The event should be made to reload the current directory, and to select the image
