Supersedes https://github.com/ppy/osu/pull/28907.
- Fix border being fat
- Fix thumbnail not masking correctly
- Fix background layer not being correctly fit to the panel
- Dim the main background on hover
- Minor tweaks to dimming
Due to the way `ModelBackedDrawable` works, the default starts to get
loaded even though a final `Beatmap` has been set. This avoids loading
the default fallback unless a beatmap has been set (and has no
background itself).
- Change difficultyicon mods parameter docstring to be more professional
- Add a parameter for controlling whether the difficulty statistics show or not. Defaults to false
- Round the BPM in the tooltip to make sure it displays correctly
Wanting to use this inside notification, it turns out that the original
design did not work very well at such narrow widths, and additionally
the typical button setup borrowed from elsewhere resulted in teeny tiny
action buttons.
To that end, slim down the design (get rid of thumbnail, audio preview,
make expandable right side slimmer), as well as change the entire panel
so that it has only one action associated with it at all times, and
clicking the panel in any place triggers that action.
