Subject: Revert "SDL: Use RLE acceleration for SDL2 transparent surfaces"

This reverts commit 6b4195a542083c97f696c843b9823d578b018996.
There seemed to be no clear benefit in using RLE for transparent
surfaces, and there were a few reports that it might cause crashes
on Windows. So to be on the safe side I prefer to revert this
commit.
