ImageProcessing playground

It seems like all of the playground examples listed in the ImageProcessing doc about colorCurves and colorGradient are buggy:

On each we can see a vector2 error in the console.

I have checked all 3 PGs (with Chrome), no errors on my side in the console (I have cleared the cache of the browser to be sure).

I confirm, it is working again on my side!
