SixtyFPS UI Library

New Features
- TouchArea: add the pointer-event callback ( 2716e4 )
  ... instead of pressed-changed
  
  This allows to see what mouse button was pressed.
  
  Closes #535
- Enable support for gzip-ed SVG images ( 7aa654 )
- Add AboutSixtyFPS element ( 4a26fa )
- Allow normal elements to be in the Dialog's button row with dialog-button-role ( ae3e1b )
- Add support for embedding data in generated C++ code ( c91a38 )
  This allows compiling with SIXTYFPS_EMBED_RESOURCES=true and images/fonts are embedded as inline variables.
Changes to the .60 language
- Show an error when not calling a callback ( 80d7b2 )
  While before it was silently ignored or caused error in the generated code.
  
  Fixes #542
Fixes
- Visit globals when finding usages of structs ( 72d556 )
  Otherwise some used struct might not be found, and they can cause compilation failure in the generated C++ or Rust code
  
  Fixes #549
- Fix granularity of run-time borrows in GL backend window handling ( e987a4 )
  When processing window specific events, or generally when accessing the ALL_WINDOWS refcell, keep the time for borrow to an absolute minimum. That way any subsequent method calls may further acquire the refcell.
  
  This patch re-organizes the entire deeply nested window event handling in a function with slightly less indentation.
  
  Fixes a panic when calling hide on a Window from within a callback handler.
  
  Fixes #539
- Fix the middle mouse button with Qt ( b0c87c )
- Fix extra '}' when doing a debug() with an enum. ( 85772d )
  The code was copy-pasted from the code that output the structs
- Bound Text contents width ( f916ca )
  The contents of a Text would wander to the left with center and right alignment because some size calculations don't take the maximum available width into account.
- Put filename in quote in import errors ( b99ff1 )
  So that the debug_assert! that fires when a error message ends with a period does not crash the LSP when typing an incomplete filename that ends with a '.'
- Fix materialized property being wrongly re-initialized when used within the same Element ( cc0d5e )
  Because the bindings field is taken in order not to keep the Element borrowed.
  
  Fixes original report from #553
- Fix panic in the interpreter if there are properties that are aliased to struct ( 7939d8 )
- Fix standard button OK text ( 7102f9 )
- Fix rendering of push buttons with QStyle on macOS ( 6dce5a )
  The button bevel was rendered upside down, which happens due to some weird double y-axis inversion, which goes away when passing the QWidget pointer to the style. When using the Qt backend, we can do that.
- Fix embedded window icon with the Qt backend ( db10bf )
  Also add a window icon to the gallery
- Fix sixtyfps-build always forcing a rebuild when a builtin image is include ( 106f1b )
  We can't call return-if-changed with "builtin:" URL, otherwise cargo thinks the build script always need to be re-run
  
  Fix the gallery example always being rebuilt because it uses AboutSixtyFPS
- Qt style: Improve default layout spacing on macOS ( 4c6c82 )
  When the PM_LayoutHorizontalSpacing pixel metric is negative, we're supposed to call layoutSpacing() on the style. Until we have a detailed overview over the controls, a default spacing is better than -1 :-)
- Qt style: Only show icons in standard buttons if the style permits ( d43e0a )
- Native style: properly initialize the layout padding ( aa05e9 )
- Fix panic with GL backend when using non-existent font families ( 30e79d )
- Further speed up font handling in the GL backend ( 0e8efe )
  Use the new fontdb API to mmap fonts from disk and avoid making copies of embedded application fonts.
- Fix ListView not always making the window to be redrawn when a model change ( 8150bb )
  Example: expending or collapsing the cargo-ui dependency tree after scrolling.
- Improve error message for parse errors ( 521bf1 )
  print the literal token symbol instead of the internal token name
- Document the current-index property of the TabWidget ( 98e1bb )
- viewer: Prettify help output ( d79894 )
Examples & Demos
- Added a bash example that shows how to display system information using sixtyfps-viewer
Janitor work

fontdb

Add the ability to share font data with the application (PR #19)
This adds a function that will convert font data to an Arc<dyn AsRef<[u8]> + Send + Sync> that's returned to the application.
If the face is backed by a file on disk, then it will be mmapped.
The load_font_source function allows supplying a pre-constructed `Source` to the fontdb. In combination with the new Source::Binary(Arc<dyn AsRef<[u8]> + Sync + Send>) variant this allow sharing application created font data with the fontdb.
