Papers 47.beta
---------------

Papers has seem mostly changes in the libraries and refactorings since 47.alpha
For packagers:

* We now require libadwaita 1.6.beta and GTK 4.15.2
* We have changed the flatpak permissions to read local files. This is necessary
to reload the document on changes regardless of the sandbox type in use
* The "introspection" configure option is now a feature instead of a boolean
* The "gtk_doc" configure option has been renamed to "documentation"

Other changes we can highlight:

libppsview:
* The gesture management of the document view has been heavily refactored.
Previously, the gesture tracking was done manually, while we are now heavily
relying on GTK4's gesture handling. This makes the experience on touchscreens
a lot more polished
* Drag and dropping into the view is no longer supported

shell:
* The Escape key now works with most dialogs
* Implement modern mockups for the annotations sidebar
* Implement changing color of highlight annotation on creation
* Modify default yellow color for annotations
* Use AdwSpinner instead of GtkSpinner where appropriate
