I have no interest in SDL for AGA but an optimized SDL for RTG could be really nice!!!
In the olden days when I looked at SDL it called a subroutine for EVERY SINGLE PIXEL in a blit. It was mind bogglingly slow. So I threw it overboard like a dead body and forgot about it. But that was 10 years ago and hopefully things have improved now?
You could have just fixed it or report the error. Why deprive the users of something that could be so great.
