- The old DPI Scale setting was replaced by DPI Scaling Info, which contains information about scale and method of scaling. - ImGui Context Manager handles scaling in ImGui by scaling all styles, rebuilding fonts using a different size, and raising OnFontAtlasBuilt event. - ImGui Module Manager uses OnFontAtlasBuilt event to rebuild font textures. - The update policy in Texture Manager was loosened to update existing resources rather than throwing an exception. This is less strict but it is now more useful since our main texture can now change. The throwing behavior used in the public interface is now handled before calling to the Texture Manager.
