INTEGRATION: CWS basebmp01 (1.1.2); FILE ADDED

2007/05/22 09:59:17 thb 1.1.2.1: #147378# Added support for foreign formats (via GenericColorImageAccessor); fixed typos in CompositeIterator and StridedArrayIterator; fixed comparisons for (Packed)PixelIterator and StridedArrayIterator (which got negative strides wrong); avoiding unnecessary copying in scale_image() now; cleaned up bitmapdevice.cxx from cruft/ad hoc debug code; made unit tests run again
