annotate src/events/SDL_resize.c @ 1228:f4a3a4129d04
From Mike Frysinger and/or Gentoo:
- libsdl-SDL_stretch-PIC.patch
ignoring the general fact of how SDL_stretch relies on executing dynamic code,
the inline asm should let gcc handle the a details for getting the actual
address for _copy_row as it will do the right thing
test case: http://dev.gentoo.org/~vapier/libsdl/sdl-stretch.tar.bz2
