Thanks to @zemarmot's new filter API, we can now import legacy Color Overlay layer styles in PSDs!

I've posted an issue to figure out how to match the other layer styles to GEGL filters, so we can implement them as well. If you're familar with either and want to help, please share suggestions.

@CmykStudent @zemarmot Before implementing the real filters, it might be useful to add dummy filters that show the values of the PSD styles. This way the user can see that styles are being applied in the original file.
@supertobi @zemarmot Ah, something to look into for the "modern" layer effect, which use a descriptor syntax. The older layer styles I looked at are predefined sections, and outside of older PSDs are only saved for historical purposes.
@supertobi @CmykStudent This is an interesting idea, indeed. Even when we can't always support porting some filters, being able to inform about them can be useful.
