SDL_CreateTextureFromSurface does not appear to correctly respect SDL_PIXELFORMAT_INDEX1LSB

[alestane]

Test case at github.com/alestane/sdl_surface_test_nff/. Provided with a packed black-white bitmap, SDL_CreateTextureFromSurface treats the contents as being in MSB order even if SDL_PIXELFORMAT_INDEX1LSB is specified

Uncomment lines 41-44 of demo.cpp to manually reverse each byte before drawing.

SDL_ConvertSurface also appears to be affected.

Thanks for the great test case! This is fixed for SDL 2.28.
