DirectFB is a thin library that provides hardware graphics
acceleration, input device handling and abstraction, an integrated
windowing system with support for translucent windows, and multiple
display layers on top of the Linux framebuffer device. It is a complete
hardware abstraction layer with software fallbacks for every graphics
operation that is not supported by the underlying hardware. DirectFB
adds graphical power to embedded systems and sets a new standard for
graphics under Linux.
