"Gradient supports at most 8 control points" on Flash/Animate-generated SWFs

[andrew-klaassen]

We've been getting some of these errors:

Gradient supports at most 8 control points ("+num_records+" has bee given) when shape verison is lower than 4!

...on various SWFs generated by Animate/Flash. I'll hopefully get a chance to narrow it down to a simple test case sometime in the next few days, and hopefully that will lead me to a solution. I'm sure that the problem is in the format lib, but I don't see a place to enter an issue there so I'll put it here. Apologies if this is in the wrong place.

The format spec clearly says, "Note that for the DefineShape, DefineShape2 or DefineShape3 tags, the SpreadMode and InterpolationMode fields must be 0, and the NumGradients field cannot exceed 8," but Flash and Animate are just as clearly creating DefineShape3 structures with more than 8 gradient records. I've attached a minimal example. FFDec parses it without any complaints.
