When you use 64 bit scanlines you introduce a mess in the
PutImage code. You have to translate the images which have
a protocol specified maximum padding of 32 bits to the internal
64 bit format. It's not worth it on any hardware we support.
Especially given how important PutImage is compared to optimal
alignment for software rendering, which is primarily what 64
bit padding was trying to improve.
