* Added some comments * Added some checking to avoid noop shifts * Added buffer length checks * Implemented (as Stephan suggested) a version of ConvertBits() that takes offsets. This new version allows to move a region of the source into a region (possibly not at the same point) on the dest while converting colorspaces on the fly. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16592 a95241bf-73f2-0310-859d-f6bbb57e9c96
