next_fli_frame - Reads the next frame of the current animation file. Allegro game programming library.

       Reads  the next frame of the current animation file. If `loop' is not zero, the player will cycle when it
       reaches the end of the file, otherwise it will  return  FLI_EOF.  The  frame  is  read  into  the  global
       variables fli_bitmap and fli_palette. Example:

          while (next_fli_frame(0) == FLI_OK) {
             /* Do stuff, like play audio stream
                or check keys to skip animation. */
             /* Rest some time until next frame... */
          }

       next_fli_frame - Reads the next frame of the current animation file. Allegro game programming library.

       Returns  FLI_OK  on  success,  FLI_ERROR or FLI_NOT_OPEN on error, and FLI_EOF on reaching the end of the
       file.
