#TTP 334976 - BLUEPRINTS: Drag-dropping can still create nodes in read-only graphs (e.g., during PIE or when viewing an anim parent graph)
#Branch UE4
#Proj GraphEditor
#Add added SGraphPanel::IsGraphEditable so nodes and objects placed in the graph can easily determine if the graph is read only.
#Change Modified SGraphPanel::OnDragLeave to restore the tooltip if a FDecoratedDragDropOp has been modified to indicate that the graph is read only.
#Change Modified SGraphPanel::OnDragOver to change the icon on the tooltip to a lined circle if the graph is read only.
#Change Modified SGraphPanel::OnDrop to exit without changes if the graph is read only.
#Change Modified FGraphEditorDragDropAction to present feedback to the user if the drag drop target is invalid. this is activated by setting FGraphEditorDragDropAction::SetDropTargetValid, this just collpases the active icon and displays a lined circle with the same tooltip when set to false.
#Add added SGraphNode::IsNodeEditable to determine if the node is currently editable, based on an evaluation of the IsEditable attribute and the parent graphs IsGraphEditable.
#Change modified SGraphNode::OnDragOver to display a lined circle if the parent graph or the node is read only.
#Change modified SGraphNode::OnDrop to exit without changes if the parent graph or the node is read only.
#Change modified SGraphPin::OnDrop to exit without changes if the parent graph or the owner node is read only.

#TTP 314475 - k2: comment boxes within other comment boxes do not move if the outer most box is moved. Also, if two nested comment boxes are moved, the nodes within move 2x as much as they should (video)
#Branch UE4
#Proj GraphEditor, BehaviourTreeEditor
#Add SNodePanel::SNode::FNodeSet typedef for conveniance and clarity
#Change Changed SNodePanel::MoveTo to take an FNodeSet as an exclusion filter on the moved nodes, once moved nodes are appended into this set.

Other Updates:
- The WidgetReflector is now in its own module as well. It will be converted to a plug-in later.
- The Public API of both Slate and SlateCore has largely been reorganized for better discoverabilty. More cleanup work is needed.
- Added a lot of missing API documentation and fixed existing ones. More and better documentation is needed.
- Removed dead code, fixed a couple things I stubled upon, and conformed to coding guidelines (NULL vs nullptr, line breaks, etc.)
Upgrade Notes:
- The Slate Remote Server is currently disabled - will be re-enabled shortly!
- If your module previously had a module dependency to 'Slate', it now also needs a PrivateModuleDependency to 'SlateCore' in its Build.cs file.
- If your module exposes in any of its Public header files types that are now declared in SlateCore, it needs a PublicModuleDependency to 'SlateCore'
- The ToolTip property type on SWidget has changed from SToolTip to IToolTip; change local variables to TSharedPtr<IToolTip> instead of TSharedPtr<SToolTip> where needed
- IToolTip is not a widget. If you need access to the actual widget that represents the tool tip, use IToolTip::AsWidget(); If you need access to the tool tip's content, use IToolTip::GetContentWidget()
Troubleshooting:
- After syncing to this changelist you may have to clean your /Engine/Intermediate/Build/ directory and rebuild your entire project
- If in your project you are getting linker errors for unresolved types that are now declared in SlateCore, you may be missing a dependency to 'SlateCore'
- If in the Engine code you are getting linker errors for unresolved types that are now declared in SlateCore, you may need to rebuild the entire Engine
