GTK+ GUI开发工具包
GTK(GIMP Toolkit)是一套跨多种平台的图形工具包,按LGPL许可协议发布的。虽然最初是为GIMP写的，但目前已发展为一个功能强大、设计灵活的一个通用图形库。特别是被GNOME选中使得GTK+广为流传，成为Linux下开发图形界面的应用程序的主流开发工具之一，当然GTK+并不要求必须在Linux上，事实上，目前GTK+已经有了成功的windows版本。
GUI 开发工具包 GTK+ 3.89.2 发布了。
依赖和新 APIs：
新的版本中，更多的 API 已被弃用，并添加了新的接口。在被删除的 API 中，可以看到有 GtkJunctionSides，gdk_window_reparent，gtk_snapshot_append 和 gsk_render_node_make_immutable。
在 GTK + 3.89.2 中新添加的 API 有 GskRoundedRect，gdk_rgba_is_clear，gtk_container_snapshot_child，gdk_rgba_is_opaque 和 GdkDrawContext，它充当 Vulkan 和 GL 上下文的基类。GTK + 3.89.2 还具有渲染节点子类，并更新了捷克语，德语，匈牙利语，意大利语，哈萨克语，俄语和西班牙语的翻译。
更新日志：
* gtk4-icon-browser works again
* gtk-encode symbolic works for icons with names containing dots
* GtkFlowBox and GtkListBox have been changed to no longer emit the ::selected-children-changed signal during destruction
* gtk-demo has gained an example for using PangoTabArray with GtkTextView
* We now support CSS border-spacing in GtkGrid, GtkBox and in gadgets
* The rendering in GDK and GSK has been further refactored. We now only draw toplevel windows, and we always redraw the whole window.
* A Vulkan implementation has been added in parallel to the GL one
Dropped APIs:
gdk_window_process_updates
gdk_window_process_all_updates
gdk_window_reparent
support for native and foreign subwindows
gsk_render_node_{append/prepend/insert} variations
gsk_render_node_make_immutable
gtk_cairo_should_draw_window
gtk_snapshot_append
GtkJunctionSides
New APIs:
gdk_rgba_is_clear
gdk_rgba_is_opaque
GdkDrawContext: A base class for vulkan and gl contexts
Render node subclasses
GskRoundedRect
gtk_container_snapshot_child
* The GSK_USE_SOFTWARE environment variable has been generalized as GSK_RENDERER. Use GSK_RENDERER=help to learn about possible values. Other environment variables that have gained new possible values in clude GSK_DEBUG=vulkan and GTK_DEBUG=snapshot.
