* Added native image handle provider support in pixmaps on openvg.Laszlo Agocs2011-03-082-0/+243
QNativeImageHandleProvider is a thin interface consisting of get() and release() functions. Pixmaps constructed with such a provider will call these functions to acquire and release a native handle, e.g. a CFbsBitmap or RSgImage pointer in case of Symbian. The behavior is largely similar to constructing pixmaps via fromSymbianCFbsBitmap or fromSymbianRSgImage, with the exception of pixmap hibernation: release() (and subsequently get()) is guaranteed to be called also in case of hibernation, allowing more fine-grained tracking of the usage and lifetime of image data.
