There undoubtedly are, but you should be aware that the details are
HEAVILY dependent on the specific target system, because the support
provided by the system for such operations varies.  For example, the
C implementation of the interactive graphic interface for the "sam"
editor differs radically among SunTools, X11, and Blit versions.

Thus, what you ask requires both general facility in use of C and
detailed knowledge of available graphics support for the target system.
Putting the two together is relatively trivial.
