Named vectorized comparison functions | |
Note that these return CoordinateExpr, not bool. Unlike most arithmetic and assignment operators, scalar interoperability is provided for comparisons; expressions like if (all(point.gt(0))) ... are both ubiquitous and easy to interpret. | |

Explicit converting constructor.
Converting from floating point to integer rounds to the nearest integer instead of truncating. This ensures that a floating-point pixel coordinate converts to the coordinate of the pixel it lies on (assuming the floating point origin is the center of the first pixel).

Return a fixed-size Eigen representation of the coordinate object.
The fact that this returns by const reference rather than by value should not be considered part of the API; this is merely an optimization enabled by the implementation.
