| void ro_gui_buffer_open | ( | const wimp_draw * | redraw | ) |
Opens a buffer for writing to.
The ro_plot_origin_ variables are updated to reflect the new screen origin, so the variables should be set before calling this function, and not changed until after ro_gui_buffer_close() has been called.
