Make begin_frame() set a rendering colorstate and depth, and provide it to the renderers via gdk_draw_context_get_depth() and gdk_draw_context_get_color_state(). This allows the draw contexts to define their own values, so that ie the Cairo and GL renderer can choose different settings for rendering (in particular, GL can choose GL_SRGB and do the srgb conversion; while Cairo relies on the renderer).
