How can I create a custom colored icon font?

How can I create custom colored icon font as Apple did for emoticons?

I'd also need a font making tool that imports .svg images.


For font making the common OS X tools are FontLab, FontForge, and Glyphs.

I understand the Color Emoji font uses png color bitmaps in two sizes in a proprietary “sbix” table, but have not yet seen info on how to make that table.
