 # Default to use ImageMagick (shipped with Slackware) instead of
 # GraphicsMagick so that octave will have at least some sort of image
-# reading capabilities.  ImageMagick limits images to 16bpp, but if you're
-# running a multilib environment, it might be easier to accept this limit
-# rather than to compile GraphicsMagick.  (thanks to Joni Martikainen)
+# reading capabilities.  It's unclear if one is recommended over the other.
+#
+# ImageMagick uses 16 bits per pixel quantum (each of the red, green, blue,
+# and alpha components) by default; GraphicsMagick uses 8 bits by default.
+# If you require more, add '--with-quantum-depth=N' (where N is 8, 16, or 32)
+# to the ./configure step of either Magick package when you build it.
+# Larger values will make your Magick package slower and use more memory.
