Code review comment for lp://qastaging/~smspillaz/compiz-core/compiz-core.optimization-inlining

Still causes the shift regression, despite us thinking it was fixed by:

It seems that fix has not worked.

Aside from the shift regression which still needs fixing, I strongly recommend not breaking the ABI (now and again in future) by inlining handle() or border(). If anything, I suggest adding new inline functions "inlineHandle" and "inlineBorder". Ideally they should be private. If not private, then they should be documented as "only safe to use in core or core plugins".

CORE_ABIVERSION still needs bumping too.
