+  = insert STRETCHED media (where image will stretch to fill the cell area)
+    and define expected cell area to be W cells wide and H cells high,
+    with the image/media/url.
+    where C is the replace character to be identified in later text
+    where W is the width in character cells (up to 511).
+    where H is the height in character cells (up to 511).
+    
+    note that this escape alone has no effect. it indicates a future
+    intention of inserting media into the terminal. the terminal will
+    EXPECT a grid of WxH "replace characters" to follow, with each
+    sequence of such replace characters bebung with a 'ib' escape command
+    and ending with an 'ie' escape command.
+    
+    example:
+    
+      printf("\033}is#5;3;%s\000"
+             "\033}ib#####\033}ie\n"
+             "\033}ib#####\033}ie\n"
+             "\033}ib#####\033}ie\n", "/tmp/icon.png");
+    
+    note that '#' is the replace character, and later '#' chars if inside
+    begin/end escapes, will be replaced by the given media indicated
+    in the insert media escape.

+  = insert FILLED media (fill in cell area). otherwise paramaters are
+    identical to the "is" command but ensures the entire area is

+it[CW;H;FULL-PATH-OR-URL]
