Please add support for background color in textMateRules

[rlnoonan]

A near deal breaker for me is the lack of ability to change the background color of comments. This makes comments stand out much more than just changing foreground color or style. I can't believe this feature isn't supported, since it seems like a popular want. As an example, I'd like to be able to add the following to settings.json:

    "editor.tokenColorCustomizations": {
        "textMateRules": [
            {
                "scope": [
                    "comment",
                    "comment.block.documentation",
                    "comment.block.documentation.js",
                    "comment.line.double-slash.js",
                    "storage.type.class.jsdoc",
                    "entity.name.type.instance.jsdoc",
                    "variable.other.jsdoc",
                    "punctuation.definition.comment",
                    "punctuation.definition.comment.begin.documentation",
                    "punctuation.definition.comment.end.documentation"
                ],
                "settings": {
                    "fontStyle": "italic",
                    "foreground": "#287a1d",
                    "background": "#c6c8c6"
                }
            }
        ]
    },

The "background" item shows a problem and when I hover over it I get the message "Token background colors are currently not supported". I do realize there are extensions, like "Better Comments" available. I like that extension a lot, but it does not work with the "DVT IDE for Verilog/SystemVerilog/VHDL" v25.1.9 extension, which I need. Since the textMateRules do work with that extension, it would really be helpful if we could specify the background color there. Thanks.
