When the page is zoomed in iOS and Android devices, lines drawn are displaced downwards and to the right. Displacement increases with image zooming.

Configurations tested:
- iOS + Safari;
- Android + Chrome;

Adding ImageEditor inside a RadPanel breaks the RadPanels designer. The problematic behavior can be observed with the following configuration:

        <telerik:RadPanelBar ID="RadPanelBar1" Runat="server">
            <Items>
                <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
                    <ContentTemplate>
                        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" ImageUrl="~/Images/Jellyfish - Copy.jpg"></telerik:RadImageEditor>
                        <asp:Button runat="server" ID="dasd" />
                        <telerik:RadEditor ID="RadEditor1" runat="server"></telerik:RadEditor>
                    </ContentTemplate>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>

When the command dialogs from two ImageEditors on a page are opened consecutively, the second dock is rendered with wrong position. The issue most probably comes from the fact the second dock element (ToolsPanel) is appended to its parent ImageEditor, but not to the form.

Assuring that each dock is appended to the form element can be used as a temporary workaround of the issue:

        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <telerik:RadImageEditor ID="RadImageEditor2" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <script>
            function ClientDialogLoaded(imageEditor, args) {
                setTimeout(function () {
                    $telerik.$("#<%=form1.ClientID %>").append($get(imageEditor.get_id() + "_ToolsPanel"));
                }, 0);
            }
        </script>

Add ability to RadImageEditor to show the progress  when saving the image to the server, displaying  back to the user how much time is left to save the newly changed image back to the server. 

The new version allows shape resizing on the image editor. 

However this is not working in a stable fashion. Here is the list of steps to replicate

a. Draw a rectangle
b. Hold the central marker to drag the rectangle. it moves slightly and then nothing happens
c. Try holding any other marker to move the rectangle it does not work
