+# 1) Just display an image centered, or in one of the four
+#    corners. --center, --tl, --tr, --bl, --br
+# 2) Display startup icons that signal initialization progress
+#    which will turn from inactive to active.
+#    Needs a directory tree where you have two dirs named
+#    inactive and active, with identically named *.ppm files
+#    in them. Call with "--reset [dir], so all images from
+#    the inactive subdir will be drawn in alphabetical order.
+#    Call with --icon [dir/active/xxx.ppm] to draw that
+#    specific icon in its active state. Will assume the
+#    screen stays intact between calls.
