BeRoPNG - A very tiny but complete PNG loader

[paul_nicholls]

Just remove DataSize:longword; and the DataEnd checks from BeRoPNG (change "while (pansichar(DataPtr)+11)<pansichar(DataEnd) do begin
" to "while true do begin" and so on, but without this it's a security leak then. :-)

Thanks I think I might just leave it then haha

cheers,
Paul
