The major unsolved problem is real-time high-quality text rendering on GPU. Skia just renders fonts on the CPU with all kinds of hacks ( https://skia.org/docs/dev/design/raster_tragedy/ ). It then renders them as textures.

Ideally, we want to have as much stuff rendered on the GPU as possible. Ideally with support for glyph layout. This is not at all trivial, especially for complex languages like Devanagari.

In the perfect world, we want to be able to create a 3D cube and just have the renderer put the text on one of its facets. And have it rendered perfectly as you rotate the cube.
