[Ohrrpgce] SVN: teeemcee/10959 Add slice clamping as a privileged sliceedit option and fix compile erro

[Ralph Versteegen]

The changes I was thinking of making:

-I was thinking of having a "Clamp left+right" setting (in fact I
already implemented it), like the way the showRight and showLeft
RelPos options work: they first clamp to one screen edge, then the
other, preferring to show either the left or right part of a
larger-than-the-screen object. But this is only useful if the slice
*isn't* Aligned to an edge, because in that case the Align effectively
clamps to one Edge, and Clamp can clamp the other. For example if you
have a tooltip at some point on the screen, and you want it to shift
to remain on-screen. Seems like that needs Left+Right+Top+Bottom
clamping, scripted or not. I had thought that this could just be
accomplished by nesting two clamping slices, but actually that doesn't
seem to work.

-Rather than using the alignLeft, alignRight constants, I was thinking
of using a different enum, so that the default value is 0, not 1, to
simplify the code, or even storing horiz and vert settings as bits in
a single int. Hmm, but I definitely want to use the existing align
constants in scripts so there's no confusion, if there are only Left,
Right and None options. These days, I always try to make the FB and HS
interfaces to something the same if possible.
