SDL_UINT64_C - Append the 64 bit integer suffix to an unsigned integer literal.

       This macro is available since SDL 3.2.0.

       This  helps compilers that might believe a integer literal larger than 0xFFFFFFFF is overflowing a 32-bit
       value. Use SDL_UINT64_C(0xFFFFFFFF1) instead of 0xFFFFFFFF1 by itself.
