Add a -p option to select the pattern to draw. The existing expanding rectangles animation remains the default, and a new "smpte" pattern fills the display with seven equal vertical bars (white, yellow, cyan, green, magenta, red and blue), which is useful to verify color ordering and channel wiring of a framebuffer display. To support more than one palette, the draw_rect() helpers now receive the color value to write instead of an index into the per-format color tables. Monochrome displays pick black or white per bar using a BT.601 luma threshold. The FBIO_UPDATE ioctl is moved out of draw_rect() into a new present_area() helper, so the SMPTE pattern can draw every bar and then update the display only once.
