//Widget engine

/*
* Let me provide an explanation of how this is supposed to work:
*	Each widget will be a library, and will have the functions defined in bdm-widget.h.
*
* At load time init is called at which point a widget should make a BDMImage for each image it plans to render, likewise for text objects. At
* that point BDM will then call getNumImages, getImages, likewise for text. At each paint the following happens:
	For each widget paint each BDMImage and BDMText based on it's current BDMPaintAttribs
	Call (*widget)->update() which will modify the BDMPaintAttribs of it's components based on information it gathers or has gathered through whatever interesting means it has of doing so.
