+// Image files are an alternate file format for storing classes and resources. The

+//
+// Image files are structured as three sections;
+//
+//         +-----------+
+//         |  Header   |
+//         +-----------+
+//         |           |
+//         | Directory |
+//         |           |

+//         | Resources |
+//         |           |
+//         |           |
+//         +-----------+
+//
+// The header contains information related to identification and description of
+// contents.
+//
+//         +-------------------------+
+//         |   Magic (0xCAFEDADA)    |
+//         +------------+------------+
+//         | Major Vers | Minor Vers |

+//         |       Strings Size      |
+//         +-------------------------+
+//
+// Magic - means of identifying validity of the file.  This avoids requiring a
+//         special file extension.
+// Major vers, minor vers - differences in version numbers indicate structural
+//                          changes in the image.
+// Location count - number of locations/resources in the file.  This count is also
+//                  the length of lookup tables used in the directory.
+// Attributes size - number of bytes in the region used to store location attribute
+//                   streams.
+// Strings size - the size of the region used to store strings used by the
+//                directory and meta data.
+//
+// The directory contains information related to resource lookup. The algorithm
+// used for lookup is "A Practical Minimal Perfect Hashing Method"
+// (http://homepages.dcc.ufmg.br/~nivio/papers/wea05.pdf). Given a path string
+// in the form <package>/<base>.<extension>  return the resource location
+// information;
+//
+//     redirectIndex = hash(path, DEFAULT_SEED) % count;
+//     redirect = redirectTable[redirectIndex];
+//     if (redirect == 0) return not found;
+//     locationIndex = redirect < 0 ? -1 - redirect : hash(path, redirect) % count;
+//     location = locationTable[locationIndex];
+//     if (!verify(location, path)) return not found;
+//     return location;
+//
+// Note: The hash function takes an initial seed value.  A different seed value
+// usually returns a different result for strings that would otherwise collide with
+// other seeds. The verify function guarantees the found resource location is
+// indeed the resource we are looking for.
+//
+// The following is the format of the directory;
+//
+//         +-------------------+
+//         |   Redirect Table  |
+//         +-------------------+

+//
+// Redirect Table - Array of 32-bit signed values representing actions that
+//                  should take place for hashed strings that map to that
+//                  value.  Negative values indicate no hash collision and can be
+//                  quickly converted to indices into attribute offsets.  Positive
+//                  values represent a new seed for hashing an index into attribute
+//                  offsets.  Zero indicates not found.
+// Attribute Offsets - Array of 32-bit unsigned values representing offsets into
+//                     attribute data.  Attribute offsets can be iterated to do a
+//                     full survey of resources in the image.
+// Attribute Data - Bytes representing compact attribute data for locations. (See
+//                  comments in ImageLocation.)
+// Strings - Collection of zero terminated UTF-8 strings used by the directory and
+//           image meta data.  Each string is accessed by offset.  Each string is
+//           unique.  Offset zero is reserved for the empty string.

+// composed of individual attribute sequences.  Each attribute sequence begins with
+// a header byte containing the attribute 'kind' (upper 5 bits of header) and the
+// 'length' less 1 (lower 3 bits of header) of bytes that follow containing the
+// attribute value.  Attribute values present as most significant byte first.
+//
+// Ex. Container offset (ATTRIBUTE_OFFSET) 0x33562 would be represented as 0x22
+// (kind = 4, length = 3), 0x03, 0x35, 0x62.
+//
+// An attribute stream is terminated with a header kind of ATTRIBUTE_END (header
+// byte of zero.)
+//
+// ImageLocation inflates the stream into individual values stored in the long
+// array _attributes. This allows an attribute value can be quickly accessed by
+// direct indexing. Unspecified values default to zero.
+//
+// Notes:
+//  - Even though ATTRIBUTE_END is used to mark the end of the attribute stream,
+//    streams will contain zero byte values to represent lesser significant bits.
+//    Thus, detecting a zero byte is not sufficient to detect the end of an attribute
+//    stream.
+//  - ATTRIBUTE_OFFSET represents the number of bytes from the beginning of the region
+//    storing the resources.  Thus, in an image this represents the number of bytes
+//    after the directory.
+//  - Currently, compressed resources are represented by having a non-zero
+//    ATTRIBUTE_COMPRESSED value.  This represents the number of bytes stored in the
+//    image, and the value of ATTRIBUTE_UNCOMPRESSED represents number of bytes of the
+//    inflated resource in memory. If the ATTRIBUTE_COMPRESSED is zero then the value
+//    of ATTRIBUTE_UNCOMPRESSED represents both the number of bytes in the image and
+//    in memory.  In the future, additional compression techniques will be used and
+//    represented differently.
+//  - Package strings include trailing slash and extensions include prefix period.
