The changes in this version are pretty random, but there is a theme of improving how to create custom widgets.

• The ttauri project is renamed to HikoGUI.
• The drawing API is more consistent and capable; for example adding color gradients, convex quads and allowing glyphs to be overlapped.
• New text-shaper and text widget which handles bidirectional text, with bidirectional-double cursors, multiple paragraphs, and sharper rendering by scaling and positioning to sub-pixel boundaries.
• Improved grid widget which now supports row- and column-spans.
• New grapheme-cluster type that can be used inside std::basic_string.
• An central API to retrieve user-settings from the operating system, including a notifier for the application to directly react on changes.
• DPI scaling is implemented by scaling the measurements of a theme.
• Multi-monitor support for positioning and maximizing.
• co-routine task and scoped_task which can await on notifiers and observables to handle complex user interface interactions and window ownership.
• New blocking main event-loop with more accurate vertical-sync support; improving animations even in debug builds.
• Improved localization support with language_tags that have access to ISO-codes for language, script and region.
