- Removed default shader platform parameter from GetGlobalShaderMap()
- Added an inline overload of GetGlobalShaderMap() that takes a feature level instead, and translates to the correct shader platform
- Cached feature level on FSceneView for faster access
- Cached shader map on FViewInfo for faster access
- Cached featurelevel/shadermap on rendering composition graph execution context, for faster access
Fixed a couple of crashes when switching feature level dynamically
- Needed to allow certain shader permutations to be generated if feature level was ES2, but still on a PC platform. (i.e. hitproxy shaders, and basepass shaders used by editor primitives system)

This commit adds the framework APIs, editor and rendering features needed to support live streaming. Along with this, we're working on a new plugin that adds Twitch.tv support (waiting for legal approval to commit.)
- Game live streaming
- Allows general support for live internet streaming of game video and audio
- Web cam video feed can be overlaid onto game viewports automatically
- New 'Broadcast' Blueprint function library allows you to easily start broadcasting from your game
- New IGameLiveStreaming API that allows you to start broadcasting through C++
- Editor live streaming
- The editor UI now displays a "broadcast" button automatically when a live streaming service is available
- Broadcasting of all desktop editor windows is supported (configured in preferences)
- If you have a web cam, video will be displayed automatically while broadcasting in a new editor window
- New "Live Streaming" editor preference tab with many new settings for configuring broadcasting
- New IEditorLiveStreaming API that lets you control editor broadcasting directly, if needed
- Added new 'Broadcast.Start' and 'Broadcast.Stop' console commands
- These allow you to easily test live streaming in games without writing UI code
- Built-in help is available for these new commands
- To implement a live streaming plugin:
- Inherit from the new ILiveStreamingService interface
- Register your "LiveStreaming" feature with the IModularFeatures system
- Other changes:
- Eliminated broken screen quad drawing functions; replaced with publicly-exposed DrawRectangle()
- Slate: Eliminated legacy code for 'marking windows as drawn' (not used anymore)
- Slate: Added Slate rendering callback to find out when a frame buffer is ready to be presented
