-/**
- *  Helper class to manage "tiling" a large coordinate space into managable
- *  chunks, where managable means areas that are <= some max critical coordinate
- *  size.
- *
- *  The constructor takes an antialiasing bool, which affects what this maximum
- *  allowable size is: If we're drawing BW, then we need coordinates to stay
- *  safely within fixed-point range (we use +- 16K, to give ourselves room to
- *  add/subtract two fixed values and still be in range. If we're drawing AA,
- *  then we reduce that size by the amount that the supersampler scan converter
- *  needs (at the moment, that is 4X, so the "safe" range is +- 4K).
- *
- *  For performance reasons, the class first checks to see if any help is needed
- *  at all, and if not (i.e. the specified bounds and base bitmap area already
- *  in the safe-zone, then the class does nothing (effectively).
