A media card like a phone's now playing, with the album cover on a Guition (0.2.77)

Browse Source 
The card behind a media tile shows the album cover, the title, the artist and
the album, a progress bar that runs while the track plays with the times at its
ends, round keys for previous, play or pause and next, and a volume row with a
mute key, a wide slider and the percentage. Keys the player lacks stay faded,
an off player shows one power key, a stream without a length shows no bar, and
the CYD shows the player's icon in the cover's place. A media tile over the
whole page is the same card under the tile's head. media_card.h holds the
geometry, tests/test_media_card.cpp checks every shape.

The cover comes the way camera images do: the screen asks with the size and
the colour behind the corners, the app fetches the picture from Home Assistant,
cuts it square, rounds the corners over that colour and serves it on port 8098;
the Guition loads it once and asks again only when the picture's mark in the
state changes. Firmware 0.2.64.
