However, for those where the starting row was offsetted (like for Animation Editor channel lists, to make the first entry more visible), these will be the min-coordinates of the first item.

  • This function should only be called from region init() callbacks, where it is expected that this is called before #UI_view2d_size_update(), as this one checks that the rects are properly initialized.
