@ -1017,7 +1017,9 @@ If WHICH overrides a standard fringe bitmap, the original bitmap is restored. *
On X, we bit-swap the built-in bitmaps and reduce bitmap
from short to char array if width is <= 8 bits.
On W32 and MAC, there's no need to do this.
On MAC with big-endian CPU, we need to byte-swap each short.
On W32 and MAC (little endian), there's no need to do this.
