Change point limits to adding points on border

When a user drags outside of the windmap, points are now added during drag instead of after the mouse re-enters broders. This results in more tangible feedback.
Added 1 to dimensions of windmap

Fixed an off-by-one error with windmap only covering top-left corners of the grid correlated to our world map bounds. Wind now has four wind vectors for every grid cell.
