Bug 106837 – [CSS Shaders] Parse @-webkit-filter

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Max Vujovic]

The new CSS Custom Filters syntax includes an @filter rule:
@filter IDENT { <custom-filter-description> }

This bug covers parsing the at-rule (not its internal properties).

Spec: https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/index.html#the-atfilter-rule

The style errors are unavoidable in order to match the local style of the enums.

Noticed that there was an unnecessary line in a JavaScript test, and removed it. The line was "exception = null" in custom-filter-parsing-common.js.
