With the recent update to `GLMakie`, I know we can set set `pt_per_unit` while saving figure created by GLMakie. What about animation? I make my animation with something like the following:
```julia
t_idx = Observable(1)
fig = Figure()
# some codes for plotting
surface!(ax, x, y, @lift(data[$t_idx]))
# some codes for plotting
if true
record(fig, savename, timestamps; framerate=framerate, compression=1) do t
t_idx[] = t
end
end
```
Are there any options for `pt_per_unit` while saving the animation?

For GLMakie it should be `px_per_unit`!

but where do I enter this option? When saving a normal figure, we can just have `save(filename, fig; px_per_unit=10)`, but what about animation?

To record!
