 * CUpnpSvgImageConverter class acts as an intermediate between the invoker and the

 * Does all the pre-processing needed before invoking actual conversion API.

 * It takes svg file as an input and provides bmp ( converted ) file as an output.

 * This class is responsible for creating a new thread and allocating resources to it.

 * The icon file conversion happens in the new thread being created.
