multiple filters with a single colorMatrix

[jure]

hi,

 

i'm working on the "example 25" in the DEV branch: https://github.com/GoodBoyDigital/pixi.js/tree/dev/examples/example%2025%20-%20Video

 

i need to apply more than one filter at the same time, in example these two:

var grayscale = [  0.3, 0.6, 0.1, 0,  0.3, 0.6, 0.1, 0,  0.3, 0.6, 0.1, 0,  0  , 0  , 0  , 1];var brightness80percent = [  1  , 0  , 0  , 0.8,  0  , 1  , 0  , 0.8,  0  , 0  , 1  , 0.8,  0  , 0  , 0  , 1];

I know about the "webgl filters" feature, but i need a canvas fallback too.

 

How can i do?

 

Thanks!
