+# How to make a wordcram that pops up extra information
+# when you click on a word.
+#
+# Each frame, we want to draw the wordcram, and some info
+# about the word that's been clicked on (or hovered over).
+# Each frame, you need to clean up what the last frame drew.
+#
+# Since laying out a wordcram is expensive, and there's
+# (currently) no way to quickly re-render a wordcram,
+# we don't want to make the wordcram in draw().
+# (Besides, each frame would probably come out different.)
+# Instead, render the wordcram in the setup() method, and
+# cache it as a PImage. Then, in draw(), render that image
+# first, which will overlay the last frame's image.
