    GizmoUI Footer Structure:

    [Button1] [Button2]

    [?] [Reset]           [Confirm] [Cancel]
    ----------------------------------------
    ~ Warnings ~


    Additional details:
        - [Confirm], [Cancel], [Done], ... are buttons that close the Tool Dialog
        - [Reset], [Button1], ... are buttons that do not!
        - Non-consequential buttons like [Cancel] and [Done] are always the right-most buttons
        - [Confirm] buttons should use the orca_button_style to differentiate them from other buttons
        - Multiple warnings can show, but should only have one ImGui::Separator above
        - If no warnings is shown, dont render the ImGui::Separator
