Add further support to the pixel format convertor to allow ARGB, RGBA, and ABGR formats to be displayed in qcam. Blank lines are added between the sections for NV, RGB, YUV, and MJPEG configurations. The implementation of the RGB conversions are highly inefficient, and where possible should be extended to use hardware accellerations such as OpenGL, or in the event that the input format is identical (or compatible) with the output format - a more optimised memcpy should be implemented.
