* @class KgImageProvider
* @since 4.11
* @short A QDeclarativeImageProvider that renders requested sprites and
* returns corresponding pixmap to the QML view.
*
* This class is a QDeclarativeImageProvider that takes a KgThemeProvider
* in its constructor and uses it to get full path to SVGs. These theme
* SVGs are read and requested sprite pixmap is extracted and given to
* the QML image element that requests it.
*
* For porting KDE games to QML, there is a KgItem QML component provided
* by KgCore QML plugin which is a small wrapper to request pixmaps from
* this KgImageProvider. See KgItem's documentation for details.
