A GtkDialog that adapts to smaller displays
Small is defined as:
| 1 2 | is_small = (( width <= 400 && height <= 800) || (maximized && width <= 800 && height <= 400)); | 
In the smaller view a HdyDialog matches it's size to that of it's parent and for "Presentation Dialogs" uses a back button rather than close button to dismiss.
It's recommended that dialog contents are wrapped in a GtkScrolledWindow to ensure they don't overflow the screen
HdyDialog works best when “use-header-bar” is TRUE (which is 
the case when using hdy_dialog_new())
Design Information: GitLab Issue
Ideally when using HdyDialog you shouldn't need to know you are using
it rather than GtkDialog however there are some notable differences:
“modal” is TRUE by default as is “destroy-with-parent” as
the behaviour demonstrated by HdyDialog would be a bad user experience
when not modal
If you want to replace the titlebar by your own, we recommend using HdyHeaderBar as it will retain the abiity to present a back button when the dialog is small. HdyHeaderBar doesn't have to be its direct child and you can use any complex contraption you like as the dialog's titlebar.
GtkWidget *
