Fix fuzziness for application icons

- Center the icon texture in the area allocated for it, and always give
  the nominal size - avoid off-by-one scaling if the parent allocated
  a little less or more size than we wanted.
- Use Math.floor() when centering horizontally to avoid allocation
  at a half pixel.
