- Improve traces.

- Changed default column width to 128 to match native and make that
  the mimimum for LVS_SMALLICON and LVS_LIST styles.
- Corrected max value for LVS_LIST style scroll info.
- Issue our own ShowScrollBar like the native with proper test.
- Correct alignment when using LVS_ICON style.
- Correct FIXMEs for unimplemented styles.
- Correct rect size computation for LVS_LIST.
- Reset scroll bars when changing styles.
- Implement WM_WINDOWPOSCHANGED.
