WidgetTexture class final
Draws widgets into textures on one device.
Holds nothing between calls but the device: each draw builds its pipeline, uses it, and lets it go. Keeping one alive between draws would mean keeping a BuildOwner and its element tree alive too, which is a caching decision a caller who draws twice a second should make and a caller who draws once should not pay for.
