			This font is suitable for framebuffer consoles on devices with a 320x240 screen, to get a reasonable number of characters (53x24) that are still at a readable size. The font is derived from the existing 6x11 font, but gets 3 extra lines without sacrificing readability. Also I redesigned a some glyhps so they are more distinct and better fill the available space.
