- Added "SDL_RENDERER_ACCELERATED" and "SDL_RENDERER_PRESENTVSYNC" on
SDL_CreateRenderer() since this reduces the CPU usage when the user
scrolls and seems to work pretty good on my systems (X5000, A1222 and
microAmigaOne). This is exeprimental. If this brings problems on your
system, you can disable them using SDL ENV variable, like below:
setenv SDL_RENDER_VSYNC 0
setenv SDL_RENDER_DRIVER "software"
