I would normally agree but I have the strong feeling that the original
Flash player does some sort of automatic conversion: it loads the JPG,
converts it to a shape and forgets completely that once it was a JPG.

At least I would recommend to create a descendant of
shape_character_def.

As for the definition: Basically it should be enough if you:
  - add the bitmap as it's only fill style
  - add one path with four edges:


  1               0
    +-----------+
    |           |
    |           |
    |           |
    +-----------o
  2               3

  The "o" marks the anchor point the path, the edges go
  counterclock-wise. Set the *left* fill style to 0 (= the bitmal fill
  style ID) and the *right* fill style to -1 (no fill).

  Note Flash *stores* the fill IDs differently (0=no fill, 1=first
  fill).

  Fill type should be SWF::FILL_CLIPPED_BITMAP.

Then everything should work just fine.
