Will do. Thanks. The only problem I see now is the Framebuffer interface using 16-bit color, which lacks transparency. With 32-bit color, this should work perfectly, and can even be extended to text rendering.

please note however, that it is up to the server to consider the
client-specified mode or not. In any case, the client should request the
actual mode by calling 'Framebuffer::Session::mode'. For your custom
server, this mode might always be equal to the client-specified one, but
when testing your component with one of the existing framebuffer
drivers, please keep in mind that the client-provided mode is just a
suggestion.

Happy hacking!
