Thanks for the report. It is now fixed.
Actually I remember I first wrote the code correctly but I test it when
parsing SWF files : the docs said that say were encoding doubles as IEEE 64
bit floats in little endian but looks like folks at Macromedia didn't manage
to implement correctly such standard . Since it was not working correctly I
made a fix swaping the bytes, thinking I was misunderstanding the encoding
while I was only mistaken by a bad documentation...
Now the question is : should we include the newest "read_macromedia_double"
and "write_macromedia_double" into the ExtLib ? :)
