Fixed some bugs in DefineMorphShape2 which prevented the SWF file from beeing parsed (r105). Now it parses and writes, the output file has the same file size and contains data but does not play in Flash Player.

Fixed the last bug in DefineFont3. The SWF File Format Specification messef my life up once more.

DefineFont3 is specified this way:

Header              RECORDHEADER              Tag type = 75.
FontID              UI16                      ID for this font character.
FontFlagsHasLayout  UB[1]                     Has font metrics/layout
.
.
.
.
FontAscent          If FontFlagsHasLayout,   Font ascender height.
                    SI16 
FontDescent         If FontFlagsHasLayout,   Font descender height.
                    SI16 
FontLeading         If FontFlagsHasLayout,   Font leading height (see
                    SI16 Font leading height following).
.
.
.
.

Guess what? FontFlagsHasLayout was parsed as false but there have been over 5000 inexplicable bytes of code at the end of the tag. Setting the FontFlagsHasLayout to true and ignoring if it was parsed as true or false will lead to the expected result. Now how can anybody know that it is true by default?
Also a nice statement is: "The DefineFont3 tag is introduced along with the DefineFontAlignZones tag in SWF 8.","The minimum file format version is SWF 8." and then in the table of DefineFont3 is written: "SWF 5 or earlier: always 0, SWF 6 or later: language code" WTF!!!!!!!!!
