In the past (with R1.7.1 on the DR1000) I found some stability problems with Xournal, related to screen updates. (Maybe it is only the combination of scribbles- and screen- updates.) So I am not sure which method to use the direct ioctl or via the liberutils-display-functions? Maybe an iRex developer can comment on this?

Providing a separate library is a good idea. The proposed interface is sufficient, maybe add a (library-)prefix to the commands to avoid conflict with local names in the application.
