+@deffn {Procedure} update-texture texture rect pixels pitch
+Update the subsection of @var{texture} defined by @var{rect} with new
+pixel data in the @var{pixels} bytevector.  @var{pitch} represents the
+number of bytes in a row of pixel data, including any padding between
+rows.  This is a fairly slow process: Better to use the lock/unlock
+mechanism in streaming textures.
