modernizr check for grayscale filters IE 10

问题

IE 10 does not support DX filters (yeaaaay) I'm currently using $.browser to detect IE 10 and implement the svg solution.

However the $.browser is deprecated and will be removed or is already removed (Yeaaaay again!!!!). So, what is modernizr's alternative for $.browser in this case?

filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /* Firefox 10+ */
filter: gray; /* IE6-9 */
-webkit-filter: grayscale(100%); /* Chrome 19+ & Safari 6+ */
-webkit-transition: all .6s ease; /* Fade to color for Chrome and Safari */
-webkit-backface-visibility: hidden; /* Fix for transition flickering */

I tried if (Modernizr.css_filters) but that didn't work

You should be able to use:

Modernizr.cssfilters

or

Modernizr.svgfilters

For targeting IE10 I think .svgfilters is the one you should be using. Here's a searchable database of Modernizr tests: http://www.browserleaks.com/modernizr#filter

These are the source files:
