//remove sdl dependency
//should use my own events
//render should have a parameter for the current renderer
//it couls store state in a different class -> it could be a mix between an immediate mode gui and normal oop gui
//Or maybe the state could be stored separately? Or have support for storing the state in widgets, and also in a separate data object. Also needs to be fast.
//Or just support using state from (also adding a deafult state to) an HTTPRequest
//it sould do it's layout in a normalized coordinate system 
//the renderer can turn it to what it needs
//Shold probably have a widget renderer that encapsulates a normal renderer
//could have 2 type of renderers -> one for httprequests and a normal one
