But you'll ultimately want to profile things especially if your text
changes often. For example, for text that would only live for a
single frame, you may find that rendering text to an image followed by
blitting that image may be slower than just rendering the text
directly.
And, while it doesn't use cached NSImages, definitely check out the
following example as it demonstrates a few approaches in obtaining
better text performance:

Thanks for the pointer, Ricky. The layout of my text is changing
pretty much continuously, using most of the screen, but the content is
relatively static. So I'm hopeful that using the layout manager to
cache the glyph rendering info will be the bit of magic I've been
missing here.
