+==== Description of swapbuffers ====
+<code c>
+The swapbuffers function is available in the winbgim implementation of
+BGI graphics. You do not need to include conio.h; just include
+graphics.h. The function swaps the roles of the current active and the
+current visual graphics buffers. It is equivalent to these statements:
+    int oldv = getvisualpage( );
+    int olda = getactivepage( );
+    setvisualpage(olda);
+    setactivepage(oldv);
