+.SH DESCRIPTION
+The
+.BR rtgrpblib_set_draftness ()
+function changes that draftness value of drawing buffer
+.I raster
+to the value specified in the
+.I draftness
+parameter. The value must be positive, and shall not be
+unreasonably small, lest drawing functions may get stuck.
+The default value is 0.5.
+.PP
+When drawing a curve, the size of each step the library
+takes will be proportional to the draftness value, but
+will also depend on other factors. Doubling the draftness
+value with halve (disregarind overheads) the time it takes
+to draw any given curve.
+
+.SH RETURN VALUES
+None.
+
+.SH ERRORS
+None.
