Rasterize the picture only when it changes, not every time raster widget paints itself. Removes include SkForceLinking.h while organizing the SkDebuggerGUI.cpp includes. This is part of the work trying to remove bugs that come from SkDebugCanvas stateful draw. Part of the state comes from some optimization that this tries to reproduce in a different way.
