annotate test/testloadso.c @ 5172:ededa1ccf91c
Switched the SDL 1.2 compatibility to use the window surface, so it's fast even when there's no hardware acceleration available.
This means that the YUV overlay now uses software, but that's okay since fast YUV code should be using the textures now anyway.
