Improved RadDock's animations

CDN support --Starting with the Q3 Service Pack 1 release you will be able to load the control scripts and skins from the Telerik CDN.

New Windows7 skin

New rendering

• Support for rounded corners. All skins support normal/rounded. To enable the rounded corners functionality of the control, set the EnableRoundedCorners property to true (by default it is false for backwards compatibility)

• Improvements of the resize functionality – docks can be now resized from all sides – right, bottom, left and corners

• Added support for nested RadDocks and RadDockZones

• The new rendering fixes several reported problems – e.g. a problem with overlapping commands when one or more docks are on top of another

• Improved loading time on the client (less JS code is executed when the dock loads). Reduced size of JavaScript calculations required by RadDock on the client for setting size, resizing, etc.

Added support for nested RadDocks
