Feature request: DirectFB and SDL driver.

[dreirund]

Ahoj,

I have the following feature request:

Make a driver that uses DirectFB.

Also, in this run, a SDL driver could also be interesting.

Use case: Support status display on targets with video out that do not have a full-blown Xorg or Wayland.

SDL seems to be included if using serdisplib which in turn needs to be compiled with appropriate options; would be nice though to have it natively.
