// SvgIconTranscoder uses WebContents to transform an svg icon (as a file or
// as string data) into an SkBitmap and thence into png compressed data which
// can be written to a png file. In principal, this technique should work for
// any data:image/ mime-types supported by WebContents, but svg is all we need
// right now. File handling happens in the browser process.
// Some validation of svg data is performed prior to asking a WebContents
// renderer process (which could potentially die on bad data) to render the
// image. Since a renderer process can be destroyed for many valid reasons,
// SvgIconTranscoder always checks if its WebContents must be recreated.
