Note: Bitmap fonts require FreeType 2.10, and support is compiled out if using an older version.
Font Rendering:
- ApplySizeAndScale now computes the desired pixel size manually (using our desired DPI) rather than calling FT_Set_Char_Size.
- This also includes the font scale, which avoids the call to FT_Set_Transform and lets us remove some workarounds for inconsistent scaling from FreeType.
- For scalable fonts the desired pixel size is passed to FT_Set_Pixel_Sizes.
- For bitmap fonts the desired pixel size is used to find the most suitable strike size (set via FT_Select_Size) and the ratio needed to scale that strike to the desired size (see GetBitmapAtlasScale and GetBitmapRenderScale).
- AppendGlyphFlags has been updated to load color data (when available), and to only exclude bitmap data for fonts that also have scalable data.
- FSlateFontRenderer::GetRenderDataInternal has been updated to handle color bitmap rendering (BGRA, sRGB) in addition to the existing grayscale rendering.
- It will also handle scaling down bitmap font strikes that are larger than the desired size, which saves space in the atlas (see GetBitmapAtlasScale).
- It won't scale up any bitmaps, as that is handled by the transform applied when batching the glyph quads for rendering (see GetBitmapRenderScale).
- Added support for disabling outline and tint for bitmap fonts (in Slate and Canvas).
- Added support for batching both grayscale (8-bit alpha-only) and color (8-bit per-channel BGRA) font quads from a font texture atlas (in RHI, D3D, and OpenGL).
- Removed unused data from FCharacterRenderData.

This change makes it possible to remove the layout and painting overhead that Slate performs every frame. The system is off by default as we continue to iterate on it.
However, this includes massive changes to batching, rendering, hit testing, and invalidation panels which are permanent changes and cannot be disabled.

[CL 7235503 by matt kuhlenschmidt in Main branch]
The curve editor supports three view types by default - an absolute view (default, matches old behavior), a stacked view and a normalized view. Stacked views draw each curve separately (so non-overlapping) and normalized against their own min/max values. The normalized view draws all curves overlapping with each one normalized against its own min/max values.
A tree view has been added to help effectively manage large numbers of curves. Selecting curves in the treeview controls which curves are visible in the view area. The treeview also supports pinning curves. These pinned curves will always be visible regardless of your selection in the tree view.
A transform tool and a retiming tool have been implemented (via a plugin) which is enabled by default. The transform tool allows you to do a marquee selection of keys and then translate and scale the positions of these keys. The retiming tool allows you to create a 1 dimensional lattice to adjust the timing of your keys with a linear falloff between each lattice point. These tools work across multiple views at the same time which is especially useful if you are representing one dimensional data (such as event keys) in a view, as it allows you to adjust this data at the same time as your animation curves. A smoothing filter has been implemented (via a plugin) to allow running highpass and lowpass filters on your keys.
Opening the curve editor in Sequencer/UMG now creates a separate dockable tab which can be resized and docked as desired. A time slider has been added to the Curve Editor which is synchronized to the playback time in Sequencer. This allows you to scrub time in the curve editor without having to find the Sequencer window and adjust time there while looking at your keys and previewing your animation in the viewport at the same time.
Rudimentary support has been added for saving and later restoring a set of curves in your current session. This allows you to do a rudimentary copy/paste of entire curves but can also be useful for saving a curve, making adjustments to it and then deciding you want to go back - simply reapply the saved curve! Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

Change 4051406 by Leigh.Swift
BuildPatchServices: Update default number of simultaneous downloads for an installer to 16 which is now well proven in the wild.
Change 4036807 by Leigh.Swift
BuildPatchServices: Added new message type for receiving updates about which files have been touched by the installation.
BuildPatchServices: Cloud enumeration is now threaded to improve speed.
Change 4036477 by Richard.Fawcett
Thirdparty: AWSSDK: Update AWS SDK to version 3.3 as speculative fix for object is used after being disposed error.
Confirmed this exception is being raised from within the AWS SDK, and _not_ in Epic code.
Advice by Amazon on AWS forums for people experiencing this exception is always to update to the latest version of the SDK in the first instance.
Change 3922493 by Justin.Sargent
Runtime: Added shortcircuit support to the ExpressionParser. More documentation to come.
AgreementExpressionEvaluator has been updated to use the shortcircuit logic so it now processes expressions lef to right as expected in all cases.
AgreementExpressionEvaluator was also updated to perform evaluation as a two pass system. The tow pass solution prevents over prompting eulas in certain scenarios where the expression would ultimately resolve true without them.
Change 3983713 by Barnabas.McManners
BuildPatchServices: Fix for verification logging error counts for unique runs. Solved the issue by using an external cache of the errors encountered each run to deduct from the total. Reporting only the delta.
Change 3966915 by Wes.Fudala
WebBrowser: CEF: Potential fix for a rare issue encountered when we attempting to release resources outside of the game thread.
Change 3955168 by Justin.Sargent
BuildPatchServices: Updated primary messaging of overall install status to now display Updating when patching an existing installation rather than Installing.
Change 3954610 by Leigh.Swift
BuildPatchServices: Fixing issue with Cloud Chunk Source which would erroneously conclude that it needed to re-download a chunk due to external system failure.
There is now an explicit concept of 'lost chunk' which is tracked and bubbled up by the system errors that cause the loss in the first place, so that each source knows exactly when it should be required to retrieve a chunk that it had already retrieved previously. Being explicit, these lost chunks can also now contribute to the total download required stat.
Also fixing some tracking that was missing to update the total download required stat if a local Install Chunk Source failed to load data from the files on disk and so these chunks needed to be additionally downloaded.
Change 3947928 by Chad.Garyet
UAT: Changing commandutils to attempt to find the Win8.1sdk signtool before the win10 one. There's currently a bug related to vs2017/server2012r2/win10sdk signtool that causes it to exit with an undefined error when signing from a service account. Using the win8.1sdk circumvents this issue.
Change 3942776 by Rob.Cannaday
Http: Fix for Mac sending up duplicate header strings
Change 3940306 by Leigh.Swift
BuildPatchServices: Refactor to isolate CoreUObject dependency and be able to compile out usage.
Change 3936655 by Justin.Sargent
Slate: Changed the invalid fontcache ensure in ShapedTextCache from always to only once to reduce ensure spamChange 3917840 by Leigh.Swift
BuildPatchTool: DiffManifests mode now also saves info for New, Removed, Changed, and Unchanged file to the output json file.
Change 3911756 by Justin.Sargent
WebBrowser: SWebBrowserView now ensures that it has a valid pointer to it's parent window in it's onpaint to avoid issues with the first frame being scaled incorrectly due to not being able to access the parent windows dpi scaling.
Change 3906670 by Justin.Sargent
Slate: Change the ShapedTextCache to hold a weakptr to the Slate FontCache instead of a reference. This will allow it to detect if the FontCache has become invalid since it was linked with the ShapedTextCache, thus making it able to avoid crashing.
Change 3889008 by Justin.Sargent
StandaloneRenderer: Made the SlateD3DRenderingPolicy more resilient to graphics device errors.
Change 3886969 by Justin.Sargent
StandaloneRenderer:Changed SlateD3DConstantBuffer to no longer check on a D3DDevice failure and instead soft fail, so the application can go through the process of attempting to re-establish the D3DDevice.
Change 3886960 by Justin.Sargent
WebBrowser: Made CEFWebBrowserWindow more resilient to issues with creating textures.
Change 3855821 by Barnabas.McManners
BuildPatchServices: Added logging of the configuration to the start of all installs.
Change 3839245 by Wes.Fudala
WebBrowser: Adding support for web browser drag regions. These are areas of a page tagged with -webkit-app-region: drag or -webkit-app-region: no-drag. The application can now pass a handler function to the browser to handle window drag events. This handler will be called if the browser detects mouse drag events inside of a tagged drag region.

WebBrowser: Release CEF related references prior to CEF shutdown.
Change 3738003 by Leigh.Swift
BuildPatchServices: Fix-ups for install stats when failures are occurring
NumFilesOutdated now only set on first run, so it is not set to the number of files that are retried.
Total downloaded data and total download requirement stats fixed up for runtime as well as final values.
Initial chunk counters now only set for first run.
Moving the GetBytesDownloaded api from cloud source to download service so that it correctly accumulates.
InstallSource was multiply attempting, and counting, recycle failures, throwing that stat out of proportion.
Change 3729851 by Barnabas.McManners
BuildPatchServices: Changed the installer's MoveFile method to default to not retry. We currently only have uses of move file which already handle retry.
