+# This is not a normal Microsoft .ICO file, but it has a similar
+# structure for containing a number of icon images. Each icon is
+# a small JPG file.
+#
+# The file has a directory header containing fixed-length
+# records, and each record points to its data at an offset later
+# in the file.
+#
+# The directory entries are 16 bytes each, and the entire
+# directory is 4KB (0 - 0x1000). This supports 256 entries.
+#
+# Multibyte values are in Big Endian format.
+#
+# Header: (offset 0x0)
+#              W    H     offset  ?? len  ?? ??
+#   Entry 0:  xxxx xxxx 00001000 xx 10a2 00 00000000
+#   Entry 1:  xxxx xxxx 000020a2 xx 0eac 00 00000000
+#   Entry 2:  xxxx xxxx 00002f4e xx 0eaa 00 00000000
+#   ...
+# 0x00001000: ffd8 ffe1 0018 ... jpeg exif and data follow .. ffd9
+# 0x000020a2: ffd8 ffe1 ...
+# ...rest of ICO entries' data...
+#
+# Header structure:
+# Offset Len  What
+#      0   2  width
+#      2   2  height
+#      4   4  file byte position from SEEK_BEG
+#      8   3  length of data
+#     11   5  ??? all zeroes
+#
+# Other notes:
+# * The index of each icon corresponds to the Icon number in dwin.h
+# * One exception is number 39: that header entry is blank, and dwin.h
+#   does not define a name for 39. This is specially handled to
