Hey Folks! Can you guess what I did today? If you guessed "resolution stuff," congrats! You're right!
Almost half of the day was spent wrestling with a seemingly innocuous feature: container previews. When you roll over a container, it shows the stuff inside in the tooltip. Or it was supposed to.
Unfortunately, due to the way mobile differs from desktop architecture, the preview image generation requires a different code path. Particularly stacked items, which require bitmap fonts be generated and rendered wherever they are needed.
