Different from Core Foundry

[9ryex5]

Without any walls on the scene, this module draws cones and circles differently from Core Foundry.

Fixed by v 0.2.0.

There could still be variations from Core Foundry because when Core determines which grid squares are highlighted, it is comparing against the concept of a circle (radius + center point) while the walled template must rely on an approximation of the circle using a polygon. This approximation can be slightly off, which can make a big difference in what edge grid squares are included. That said, I think I have matched what should happen in the no-wall versions for the current Core templates.

For example, this image is actually of the Foundry circle (blue) with the walled-template version (red) laid over top. They look identical, but are not in fact identical:

If you find other cases where the templates appear off from what you would expect in Core, please let me know and I can see if I can tweak the algorithm further.
