It's impossible to do -webkit-filter: grayscale(1)

[emilsundberg]

The sass function grayscale breaks the browser filter function grayscale. This has been fixed, but doesn't work with phpsass.

GitHub issue: sass/sass#239

They have a workaround, but it doesn't work either in phpsass:
-webkit-filter: #{'grayscale(1px)'}

This is really an issue. Is there any workaround for phpsass?

[emilsundberg]

@nick4fake I haven't found anything. I dropped phpsass in favor of the real ruby gem to get rid of these kind of problems

I have made a pull request to fix this. Hope it helps.
