Watermark is not applied to srcset

[cboelter]

I'm trying to use the watermark function inside the galleries but this is not working if the attribute srcset is set. At the moment isotope only generates a watermarked image for the attribute src: https://github.com/isotope/core/blob/2.8/system/modules/isotope/library/Isotope/Model/Gallery/Standard.php#L386
I think there should be also a handling for the srcsetotherwise for this attribute the original images are used.

If you agree I will be able to create a pull request. My approach would be to split the comma separated list of sources and change the image path with the watermarked path.

Shouldn't it be possible to access the list of images before the string is created? Maybe we can influence the image creation directly through the "new" Image methods

I talked to my customer and he deciced to not use the watermark at the moment. If he changed I will able to work on the watermark again.
