^^^^^^^^^^^
The graphics capability consist both of components internal to the RTOS
and of user-callable interfaces. In the NuttX kernel mode build there are
some components of the graphics subsystem are callable in user mode and other
components that are internal to the RTOS. This directory, nuttx/graphics,
contains only those components that are internal to the RTOS.
User callable functions must, instead, be part of a library that can be
linked against user applications. This user callable interfaces are
provided in sub-directories under nuttx/libnx.

Common callable interfaces that are, logically, part of both nxmu and nxsu.

NOTE: There is no nxsu sub-directory in nuttx/libnx. That is because this
separation of interfaces is only required in the kernel build mode and
only the multi-user interfaces can be used with the kernel build.

This is the NX multi user "front end". When combined with the generic "back-end"
