v0.8.19

New in 0.8.19

• Graphics (GPU) card on Overview. How busy the graphics chip is now and over the last hour, a chart of that hour, graphics memory in use, and which apps are using it right now.
• GPU on the Processes tab. Sort by GPU, and a "GPU 23%" pill on any process using the graphics chip.
• Checkup finds apps keeping the graphics chip busy. After 5 minutes of steady use by an app in the background (or flat out in front), it says what to do for that kind of app: find the tab in a browser, stop a local AI model, lower a game's settings. Buttons for Quit, Low Power Mode on battery, and Optimise screen when drawing the screen itself is the cost.
