Added "const" to many parameters.

Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.
Note: some functions of PicturePlayer don't appear to be implented by PictureDataWriter,
