I think i detected a bug in the .flc playing routines (no in the .fli)

It's hard to explain, but I try it:

When you are playing a flc (not fli) file, if the update between the
old frame and the new one needs to update two or more horizontal
continuous lines (even with different start-end points), it seems the
routines only update the last one.

Example:

Old Frame	New Frame (theorically)	New Frame (in practice)
------------	------------		------------
------------	----********		------------
------------	--**********		--**********

(more or less)

I tried to generate the same 'movie' in fli and in flc format (the two
at 320*200). The fli file is shown as it must be, but the flc
(theoricaly the same as the other format) is shown with part from the
previous frame which must be overwritten.

If Shawn needs fli/flc examples, I could post then to him.

Oh, I played the two fli/flc files with the 'official' aaplay for Win,
and the two movies are shown correctly.

And I hope I didn't wrote an orthographical or gramathical mistake.
