- add string, int, color and resource loading helpers - use typed resource classes, and some cleanup in loading code - remove abstract GetResource() to enforce type safe access - add height and width query methods to resources and use them - minor cleanup - simplify LoadPlacement Change-Id: I9b81785109a80b3806ad6b50cba4d893b87b0db1
