The docs for uncompress() are not clear how it deals with the position of
the byte array.  The docs are better in Flex 3 than Flex 2 but the new
addition seems to indicate it tries to decompress the entire byte array
which would cause failure in the case of a SWF since the first two headers
for SWF are uncompressed and the rest of the SWF is compressed (i.e., can
ByteArray.uncompress() handle data that is partially raw and partially
compressed?)
 
This is the part that gives me pause:
 
"
After the call, the length property of the ByteArray is set to the new
length. The position property is set to 0.
"
 
Is it correct to set position back to 0 if position was not 0 to start with?

Yes, it's possible. You can use the uncompress() method of the ByteArray
class to uncompress the compressed part. You don't have to write a
decompressor, but you do have to write a bit-by-bit reader.
