int ggiCopyBox(ggi_visual_t vis, int x, int y, int w, int h, int nx ,int ny);
DESCRIPTIONThis is a area-to-area-blit, all in the same visual. Copy the box described by x, y, w, h to the new location nx, ny. This automatically takes care of overlaps and optimizes for the given visual (e.g. uses HW-accel or intermediate buffers as appropriate).
ggiCopyBox will transfer an area between frames when the read frame is not the same as the write frame.
