SVN commit 1187367 by zachmann:

use stack.reserve(3) here so that the stack is not resized all the time
this reduces the number of a/de/re-llocations for documents with
a lot of enhanced path shapes quite a lot.

In the used test document the number of a/de/re-llocations are reduced by
25%-50% for the various objects.
