- Fix potential reading/writing 1 byte behind it's own buffer in PLY loader.

- ICursorControl::isVisible is now always returning the flag set in setVisible.
This changes the behaviour on Win32 somewhat when Windows returned a CURSOR_SUPPRESSED state (touch-screen input).
Previously we set IsVisible it to false when CURSOR_SUPPRESSED was set.
