Mod to Cut/Paste Ore patches around.

Use the Shortcut Tool:
Primary select = Cut resources - This is limited to one resource at a time (By default: Left Click + Drag)
Alternate select = Paste resources - if there's room, paste your resources in the area you select (By default: Shift + Left Click + Drag)

Natural (noise) placement:
By default, ores are pasted as a filled rectangle matching your selection.
Turn on "Natural (noise) placement" in the mod settings to paste them as an organic patch instead - a single solid body with an
irregular outline, richest in the centre and thinning out toward the edges, much closer to how the map
generator makes patches.

Two settings shape the result:
Natural placement falloff (1-10, default 2) = How much lighter the yield gets toward the edge of the patch. The edges never fade away to nothing.
Natural placement waviness (0-0.9, default 0.3) = How lumpy the outline is. 0 gives a smooth ellipse; higher values make the edge bulge in and out. Very high values cut the outline in deeply, making the patch noticeably smaller than the area you selected.

The patch always stays one connected body - no gaps and no scattered single tiles - and the total amount
of ore is preserved exactly however it gets shaped. Natural placement applies to solid ores only; fluids
such as crude oil are always placed on an even grid.
