Custom inspectors do not repaint properly

[Tim Williams]

The method detailed in the manual to create a custom inspector which uses Odin does not properly repaint lists and other animated elements on the inspector.

For example, if you have a field which is a custom class being drawn by your custom inspector, when expanding/collapsing the foldout for the class field the animation will freeze until you click on the inspector window again to force a repaint.

I have fixed the issue manually with the line added at the end of the below code.

public override void OnInspectorGUI()
{
        InspectorUtilities.BeginDrawPropertyTree(Tree, true);

        //Draw some properties...

        InspectorUtilities.EndDrawPropertyTree(Tree);
        GUIHelper.CurrentWindow.RepaintIfRequested();    //This line allows the editor to repaint correctly for animations
}

It would be great if InspectorUtilities.EndDrawPropertyTree(); called RepaintIfRequested() automatically, so that users don't have to remember to call it themselves in every custom inspector.
