QgsRasterLayer is still so tightly bound to GDAL, that I agree with 
Marco's suggestion.  The easiest approach is to use the wms provider as 
a guide. The tile provider will basically be responsible for obtaining 
and merging all of the tiles together into one new QImage, which will be 
return by QImage* draw(QgsRectangle, int, int)
