The Wii U has a very limited pool of memory for render targets (32MB), so we should only use it if we have to. This 'fixes' a bug in the enhanced branch, where if you use 2x sprites at 854x480, the third line of the text box will be corrupted (text will appear on the second line instead, and be black instead of white). The other renderers haven't been updated for the API change yet.
