Move global variable textfaces in XTheme. Move global variable fontsDB in XTheme. Remove XTheme member SVGParser. SVGParser is deleted just after use. Remove XTheme members ImageSVG and ImageSVGnight. All images are rasterized at load, so no need to keep that. Remove XIcon setFilled because XIcon knows if it's filled or not by checking Image & ImageNight
