Checks if a point is inside the rasterized region.

The coordinates of the point are floored to integer values and we check if they would be present in the rasterized region. This can have unexpected consequences, like (10, 10) not being contained in a ERectangleRegion of width/height 10 centered on (5.1, 5.1) but it guarantees the equivalence with successor classes.
