Changes:
  * Made font rendering a bit faster, again.
  * Allow pixel-perfect positioning of text via -X/-Y flags.
    This is much less heavily sanitized than other options, so it can silently
    let you push stuff off-screen.
  * Fixed a couple of stupid Makefile issues, notably one that hilariously broke shared builds (thanks, @codex-hex !).

API Changes:
  * Add hoffset & voffset fields to FBInkConfig (for pixel-perfect text positioning)
