— Only align OFVector4D where necessary
Changing the alignment of OFVector4D globally (as was done previously)
would have technically been an ABI break in extremely rare cases.
However, since we only need the alignment for the methods added after
1.0, it's better to only have the alignment there and get back to full
ABI compatibility with 1.0. (user: js, size: 19548) [annotate] [blame] [check-ins using]
