# Observations:
#
# - This package is expected to work normally, like any other packaging format (e.g. Flatpak, AppImage).
# - Native Wayland support, albeit doable, is currently not done on purpose, for a few reasons:
#
# 1. It's currently awkward to package/configure properly:
#  - Due to 'strict' confinement, we have create a wrapper script and configure the Wayland socket to be visible in $XDG_RUNTIME_DIR: 
#    - https://forum.snapcraft.io/t/wayland-dconf-and-xdg-runtime-dir/186
#    - https://github.com/MirServer/graphics-core22/issues/6#issuecomment-1558815412
#
# 2. It currently has some UI inconsistencies (these were tested on Ubuntu 22.04 with GNOME 42):
#  - The mouse cursor theme is chosen incorrectly
#  - The mouse cursor itself is way larger than normal
#  - Modal windows don't have their initial position on the screen set correctly
#  - Windows don't have shadows
#
# I'm sure these issues can be worked around somehow, but since the 'X11 build' works reasonably well on Wayland through XWayland,
# they can be dealt with some other time.
# But if you're interested in Wayland support right now, here's what you have to do to get an initial, working build:
#
# - Add the 'qt6-wayland-dev' package to 'build-packages'
# - Add the 'qt6-wayland' package to 'stage-packages'
# - Either add a Wayland launcher script (mentioned in reason number 1), OR run the app like this (for quick testing):
#   $ snap run --shell notes
#   $ export XDG_RUNTIME_DIR=(dirname "$XDG_RUNTIME_DIR")
#   $ export QT_QPA_PLATFORM=wayland
#   $ notes
