- Fix errors if a theme api is missing. - Add callback to functions for drawing themed transparent background. - Fix drawing glitch when theming is applied. - Redraw on theme change: automatically redraw the window if the theme is changed while the application is active. - Colours are now declared though RGB() macro. - Removed safe DS_SHELLFONT declaration.
