-Expected changes to come:
-
-* Handle new isolated direction overrides in bidi.
-* Handle type 14 tables for variation selectors, not that anyone is using them yet.
-* Handle fonts with not glyf/loca table (e.g. cff & svg-ttf). bbox is 0,0,0,0

-/* Note on error processing: The code guards against bad glyph ids being used to look up data
-in open ended tables (loca, hmtx). If the glyph id comes from a cmap this shouldn't happen
-but it seems prudent to check for user errors here. The code does assume that data obtained
-from the TTF file is valid otherwise (though the CheckTable method seeks to check for
-obvious problems that might accompany a change in table versions). For example an invalid
-offset in the loca table which could exceed the size of the glyf table is NOT trapped.
-Likewise if numberOf_LongHorMetrics in the hhea table is wrong, this will NOT be trapped,
-which could cause a lookup in the hmtx table to exceed the table length. Of course, TTF tables
-that are completely corrupt will cause unpredictable results. */
-
-/* Note on composite glyphs: Glyphs that have components that are themselves composites
-are not supported. IsDeepComposite can be used to test for this. False is returned from many
-of the methods in this cases. It is unclear how to build composite glyphs in some cases,
-so this code represents my best guess until test cases can be found. See notes on the high-
-level GlyfPoints method. */

-Description:
-A set of fast template based decoders for decoding values of any C integer
-type up to long int size laid out with most significant byte first or least
-significant byte first (aka big endian or little endian). These are CPU
-byte order agnostic and will function the same regardless of the CPUs native
-byte order.
-Being template based means if the either le or be class is not used then
-template code of unused functions will not be instantiated by the compiler
-and thus shouldn't cause any overhead.

+ . Bug fixes:
+ . Enforce fonts having to store glyph attributes by monotonically increasing attribute number
+ . zeropadding was not getting called on feature tags
+ . automatic associations for unassociated characters
+ . use direct engine on Mac
+ . various extreme case reading 1 past the end errors fixed
+ . remove tabs from sources so that it becomes readable again

+/* Note on error processing: The code guards against bad glyph ids being used to look up data
+in open ended tables (loca, hmtx). If the glyph id comes from a cmap this shouldn't happen
+but it seems prudent to check for user errors here. The code does assume that data obtained
+from the TTF file is valid otherwise (though the CheckTable method seeks to check for
+obvious problems that might accompany a change in table versions). For example an invalid
+offset in the loca table which could exceed the size of the glyf table is NOT trapped.
+Likewise if numberOf_LongHorMetrics in the hhea table is wrong, this will NOT be trapped,
+which could cause a lookup in the hmtx table to exceed the table length. Of course, TTF tables
+that are completely corrupt will cause unpredictable results. */
+
+/* Note on composite glyphs: Glyphs that have components that are themselves composites
+are not supported. IsDeepComposite can be used to test for this. False is returned from many
+of the methods in this cases. It is unclear how to build composite glyphs in some cases,
+so this code represents my best guess until test cases can be found. See notes on the high-
+level GlyfPoints method. */

+ significant byte first (aka big endian or little endian). These are CPU
+ byte order agnostic and will function the same regardless of the CPUs native

+
+ Being template based means if the either le or be class is not used then
