+	8. Draws a string to the display.
+	9. Releases the font.
+	10. Discards the font.
+	11. Glyph cache is filled by looping. The glyph cache heap should be large enough
+		for all subsequent loops, if the glyph tree is successfully deleted after the font is
+		discarded. 
+	12. Waits three seconds after the loops complete for the first time. Then records the free RAM.
