fixing some normalized space calculation issues

I need to review the convention I'm using for the "view" or at least how I interpret these coordinate spaces so its inutitive for the interface.
At the end of the day, the draw_list should be in normalized space, however how it gets digested to that state needs to be better documented or made more explicit in its transformation from the usual user calls.
