MAJOR FEATURES + CHANGES
==========================
Change 2756103 on 2015/11/05 by Jamie.Dale
Implemented UFont::GetResourceSize to work correctly with the Size Map tool
Change 2756104 on 2015/11/05 by Jamie.Dale
Changed the font used when a font is missing or invalid to be the last resort font, rather than the localized fallback font
The localized fallback font could cause different results based on your culture, and the last resort font makes it clearer that something is set-up incorrectly as it just draws invalid glyph markers for all of the text.
Change 2756105 on 2015/11/05 by Jamie.Dale
Fixed a crash when using an empty FKey property with a Data Table
FKeyStructCustomization was asserting because there were no objects being edited, due to a newly added Data Table containing zero rows.
I've removed this assert, and also updated SKeySelector to no longer require a separate argument to say whether multiple keys with different values are selected (this is now calculated from the call to get the current key, which will return an empty TOptional for multiple values).

Change 2757156 on 2015/11/06 by Joe.Tidmarsh
Implemented "Go to Variable" functionality for widgets in Widget Blueprint Editor.
When we switch modes in UMG from Designer to Graph. We select the variable (In "My Blueprint"), if one exists, for the currently selected widget. Additionally we update the details panel.
* Added SelectGraphActionItemByName to FBlueprintEditor. This selects an item in My Blueprint and also displays it in the details panel of graph mode. SMyBlueprint is not available to FWidgetBlueprintEditor in UMGEditor module as it's privately implemented within Kismet.

Change 2757181 on 2015/11/06 by Jamie.Dale
Cleaned up some duplication in UMG text widgets, and exposed the text shaping options
The common properties used by all text widgets that are text layout based have been moved into a UTextLayoutWidget base class, and all text layout based widgets now derive from this.
The options needed to control the text shaping method used by a text based widget have been exposed via the FShapedTextOptions struct. This contains a way to manage these optional (and advanced) overrides. You typically wouldn't change these from the default unless you knew exactly what you were doing (eg, you have a text block containing only numbers).
This change also updates SRichTextBlock to work with an invalidation panel in the same way that STextBlock does

#UE4 #Editor
- Added support for meta=(TitleProperty="StructPropertyNameHere") on properties of type TArray<FSomeStruct>.
- This changes the editor rolled-up display of these values from "{0} members" to a stringified version of the specified property (if found).

Slate - Improving the way we track references to materials in slate to better keep things alive until they're no longer needed for rendering. Additionally, making it so the we use the material and texture free list when possible when cleaning up things as to not allocate new memory if not required. Concidentually this can help with problems with corrupted memory on destruct as well, because it means the memory isn't really going to become garbage any more.

Change 2760954 on 2015/11/10 by Nick.Darnell
Slate - A bug in the introduction of custom rendered elements accidentally broke filling out the texture coordinates for standard material usage. Materials should once again tile correctly just like images do.
#jira UE-23118
Change 2761129 on 2015/11/10 by Nick.Darnell
Slate - Removing the Pre-Multiply alpha path the way it was added, introducing it in a way that doesn't require changes inside the shader. Continuing to improve the SRetainerWidget to no longer have a frame delay between resizes and painting, also working on getting it handle clipping correctly but still not there yet.

Change 2762407 on 2015/11/11 by Jamie.Dale
UDataTable::SaveStructData now writes out dummy data when RowStruct is null
This didn't used to happen, which would cause a miss-match between what UDataTable::LoadStructData was expecting, and would result in a Data Table that could never be loaded again.
This change also improves the error message when editing a Data Table with a null row struct, and adds the editor-only RowStructName property to cache the name of the last used struct (for error reporting).
#jira UE-22789
Change 2762508 on 2015/11/11 by Nick.Darnell
UMG - Making it more obvious what keys do special stuff with anchors in UMG. Fixing the way snapping to anchors works with Control, it now only zeros out the side you're dragging instead of the entire widget, which was silly. Enhancing the designer message system to no longer be based on an enum and instead let arbitrary systems push and pop FText messages. Fixing animations in the anchor drop down to properly animate, broke when we introduced active timers.
Change 2763241 on 2015/11/11 by Nick.Darnell
Slate - We no longer allow popup windows to be larger than the primary display window for windows where max width/height is unspecified. This is to prevent accidential creation of tooltip windows that are larger than the driver allows causing crashes.
#jira UE-20336
#jira UE-11822 - Add up vector, roll and scale properties to USplineComponent which can be used when calculating rotations/transforms at a point on the spline
#jira UE-13333 - BP spline components do not update when setting points
#jira UE-3637 - SplineComponent: Add a get transform at distance accessor
Summary of changes:
- FInterpCurve now natively understands looping. A input key can be set, at which point the spline will loop back to its start point. Adjusted FInterpCurve methods to take looped curves into account.
- Fixed bugs in FInterpCurve regarding returning default values (T(ForceInit) instead of T() otherwise FVectors and FQuats are not initialized correctly).
- SplineComponent now holds three separate splines (location, rotation and scale).
- The SplineReparamTable is no longer transient, but is built and saved as part of the asset.
- Changed the SplineComponent API. All methods now take a ESplineCoordinateSpace value which specifies whether the values are intended for use in local or world space. The old methods have been deprecated but not removed (for now).
- bAllowSplineEditingPerInstance is deprecated. A new member (bSplineHasBeenEdited) has superseded it, and is set automatically when editing the spline with the visualizer. Added "Reset to Default" option in the visualizer, which restores the archetype defaults.
- SplineComponentVisualizer determines if spline points have been initialized by the user construction script, and, if so, will disallow editing. This is to conform with the general idea that the UCS always overrides property values.
- Fixed a number of bugs in the visualizer, and added new facilities to allow the scale and rotation to be edited (still work-in-progress).

- Changed USplineComponent::SplineReparamTable to a transient member and force rebuild each time in PostLoad() / PostDuplicate().
- Initialize the SplineReparamTable size at the start to save needless reallocations (as its size is known from the beginning).
- Added menu options to set spline key types (curve, linear, constant)
- Added Reset to Automatic Tangent to allow resetting to either a clamped or an unclamped tangent.

#add Added a new FUICommandList::ProcessCommandBindings overload, which can be called from a Viewport Client's InputKey() method (in the absence of an FKeyboardEvent object).
#add Fixed key binding handling in SplineComponentVisualizer so that it works through the FUICommandList, instead of being hardcoded.
#change USplineComponent - changed method by which spline reparam table is created (now uses the old method of splitting each segment into a fixed number of steps, instead of using fixed arc length reparameterization, which doesn't lead to such good results where the distance between control points varies largely throughout the spline). The ReparamStepsPerSegment parameter remains, although I'd like to remove it when I can hit upon a better way to adaptively step through the spline. Merged UpdateSplineReparamTable and AutoSetTangents into a single UpdateSpline method.
#add Added a parameter to FInterpCurve::AutoSetTangents - bStationaryEndpoints - which determines whether the endpoints should be assigned zero tangents, or whether the tangents should be set in order to extrapolate the curve beyond the endpoints, essentially providing a constant velocity at the start/end.
#add Added bStationaryEndpoints as an editable parameter to USplineComponent. Use this if you only wish to traverse the spline at constant velocity, as it will lead to more accurate results.

Breaking changes include:
* Rename of GEditorModeTools -> GLevelEditorModeTools to signify that it applies only to the level editor modes
* Addition of FEditorModeRegistry, responsible for managing and creating new editor modes. Modes are no longer registered with an instance of the mode, instead with a mode factory that is able to create a new mode of that type.
* Editor modes now operate on FEditorViewportClients rather than FLevelEditorViewportClients
* Added ability to specify an FEditorModeTools when creating an FEditorViewport
Moved component vizualiser manager handling outside of individual editor modes, and into FLevelEditorViewportClient. This should make it easier to transplant in future.
This work addresses TTP#334640 - EDITOR: Investigate making editor modes a per-'editor' concept

#change FInterpCurve now uses a binary search to obtain the correct key. Removed the optional out-parameter on Eval, EvalDerivative, etc. Removed FORCEINLINEs on large methods.
#change USplineComponent now builds the remap table with points spaced at equal distances, which leads to better results. Added internal methods to obtain the segment length, and the interpolation parameter along the segment at a given distance.
#add Added Duration to USplineComponent.
#add Added a number of different methods for obtaining position, tangent and rotation at a specified distance, or a specified time (optionally at constant velocity).
#add Added methods for building the spline procedurally.
#add Supports right-click context menu on ComponentVisualizers in the standard interface.
#add Key tangents can be manually edited.
#change FLevelEditorViewportClient::ProcessClick now handles right clicks to the Unreal gizmo in the same manner as left clicks, i.e. the method recurses using a version of the hit proxy with the gizmo removed, so we can look at what's underneath. This allows for "genuine" context menus, i.e. depending on what was clicked, instead of using a single default provided by the current level editor.
