1. SDL_CreateTextureFromSurface() now tries to find surface's pixel format. 2. SDL_CreateTextureFromSurface() now has best texture format search for non-alpha pixel formats. 3. Added comparision for pixels packed order to the video mode sorting callback to avoid mixing 1555/565/4444 pixel formats. 4. Added sorting call for current video mode list after each new video mode addition, because SDL_GetClosestDisplayMode() requires video modes to be sorted, and this is one place only where we can detect video modes addition.
