(Whiteboard: [viewtransitions:m1:gfx])

This is not strictly necessary per spec, but may be in practice to avoid blowing up memory usage if there are many snapshottable pictures.

The idea is to keep have a memory budget for snapshots and lower the resolution of off-screen snapshots if we go over the budget. Lowering the resolution may just be a matter of messing with the device_pixel_scale of the pictures, or it might be a lot more complicated than that.
