+
+Squeeze Extension to the ImageTransform plugin
+
+The class provides the methods to set the squeeze parameters and is intended to be implemented
+by the plugins supporting the squeezing of the images. The client can set the desired max size
+(in bytes) of the squeezed image and it can also enable auto resizing of the image by setting the
+advanced squeeze parameters. The plugin supporting this extension must use the opaque_data v2 format 
+in RSS file and also the squeeze flag must be set in the opaque_data. The client must 
+retrieve this extension implementation from the plugin using its extension UID.
+
+In the case where the client's desired size cannot be met the operation will squeeze to the
+smallest file possible and the transform operation will leave with KErrGeneral. The output file
+must be examined by the client to determine its suitability. The client must clean up if the
+output is not acceptable.
