If it is not too device specific, I can put it on a branch and we can
haggle through the details before merging it to master.
I think your original proposal for nx_updatedisplay() would be okay
if it were renamed and took three arguments like:
int nx_synch(NXWINDOW hwnd, int cmd, unsigned long arg)
it would be prototyped in include/nuttx/nx/nx.h and there would
probably need to be a new include/nuttx/nx/nx_ioctl.h to hold IOCTL
commands and structures.
These are things I can help with.

Yes, I already did some name changes because they were too close to
already used terms. Let me build this strawman and then we've got
something to work from.
