Colors are generated asynchronously now and the TimelineItem is
updated when the color generation finishes. This allows the UI
to stay responsive while new colors are being generated.
When opening images in the full-screen overlay, there is now
a download button next to the close button. This button utilizes
the same functionality as the right-click->save image button.
Restored the emoji picker, but it now falls back to the system
instead of forcing Emoji One. The allows users to user the
picker for convenience, but doesn't enforce the emoji style on them.
Add initial loading of qt jdenticon plugin:
https://github.com/redsky17/qt-jdenticon
Currently, the library's functionality has not been integrated
into the rest of nheko. Next step is to add a configuration
item in the User Settings and use the plugin to generate
avatars for users without their own picture. These avatars
should be cached in the Cache object.
User colors are now stored in cache. This is consistent
with other similar variables. I think there's a bug
right now where it doesn't properly refresh colors
for the TimeLineItem when the theme is changed.
When user is mentioned (via matrix 'highlight_count'), inactive
rooms will use a different color for the notification circle than
when only general unread messages exist.
Author color is now cached so that it will not be re-calculated
each time a new message is posted. This cache gets cleared when
the theme is changed.
Additionally, the author color is now automatically refreshed
when the theme is changed, fixing the issue where you had to
change rooms before the colors would switch.
Update the author color generation. Now, instead of generating
an entire hex string based on the user id, the user id instead
is used to generate a hue value. After this hue value is created,
there is some logic to tweak first the lightness and then saturation
values to achieve a readable color (in contrast to the background).
This change makes it so that user colors will not vary as wildly
between the different themes.
The values still are not cached and still do not update
initially when the theme is changed. Both of these things
will be resolved.
