Other Changes:
- Window: Fixed InnerClipRect right-most coordinates using wrong padding setting (introduced in 1.71).
+- Scrollbar: Avoid overlapping the opposite side when window (often a child window) is forcibly too small.
- Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because
of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).
- Scrolling: Added SetScrollHereX(), SetScrollFromPosX() for completeness. (#1580) [@kevreco]
