/* Sample module fills the frame with white pixels in a non-threaded manner,
 * replace the body of stub_render_fragment() with your own algorithm.
 *
 * To finalize a module implementation derived from this stub, perform a global
 * substitution of "stub" with your module's name, including copying into
 * src/modules/$name, and updating all the build system and til.c references.
 *
 * A quick way to see what's involved in introducing a new module is to just
 * `git show` the commit adding this stub module to rototiller.
 *
 * XXX: Note that since this module has the TIL_MODULE_EXPERIMENTAL flag set, it
 * won't appear in the modules list or participate in randomizers.  You can stil
 * access it explicitly by name via the ":" prefix override, e.g.:
 * rototiller --module=:stub
 *
 * Or just remove the TIL_MODULE_EXPERIMENTAL flag during development so it's
 * treated normally.
