Image with color matrix filter renders in the wrong colour

[MrCheeze]

Issue occurs in this flash here: https://www.homestuck.com/flash/hs2/00090/00090.swf

On clicking the green button, a green background image will appear. (works fine)

On clicking the blue button, the same background image appears, modified by a color matrix filter. In flash player, it shows up as a bright cyan, but in Ruffle it instead appears pale and greenish.

Testing Nightly 2020-11-20, issue occurs in both the web and exe version.

Another subtler issue that happens in the same flash: In flash player, the STRIFE! text that appears only on first load flashes brighter and darker in flash player, but just stays at its original appearance in Ruffle. Not sure if this is related or unrelated to the other issue, though.

I guess this isn't anything special, just a feature not yet implemented (https://github.com/ruffle-rs/ruffle/issues/15 and https://github.com/ruffle-rs/ruffle/issues/295)

With the merging of https://github.com/ruffle-rs/ruffle/pull/11702 , this is now working perfectly! :)
