we are facing very high performance issues with Camera plugin. The functionality of the plugin is to launch Camera and display the viewfinder data
on a user specified window in the widget. 

This plugin is implemented as windowed plugin. Viewfinder data is displayed as follows

on loading the plugin we invoke startViewFinderBitmaps() api provided by CCamera. This api invokes the callback function with each frame provided as
bitmap data. We convert this bitmap data into QPixmap in the callback. A signal is emitted from the callback to the plugin with the QPixmap. This QPixmap has
to be drawn into user specified window. To do this we invoke repaint() api in the slot and draw the pixmap in the overloaded paint implementation.
