NativeRenderer's Draw function is called for drawing a GTK widget composited with cairo state. NativeRenderer calls cairo_draw_with_xlib that has lot of dependencies on cairo_xlib*. cairo_draw_with_xlib does all the fancy stuff (complex transforms) and finally calls NativeDraw with the Drawable associated with the cairo surface. cairo_xlib provides API to obtain Drawable associated with a given Cairo surface. | NativeRenderer's Draw function is called for drawing a GTK widget composited with cairo state.

Effect of disabling cairo_draw_with_xlib is that the SVG and Canvas will not work; but native theming will work fine. | ||
