Feature Request: Mound Generator for the map editor

[awsdert]

What I'm imagining is a UX to the side of the map overview that allows deciding the layers of blocks to generate the mounds with. For the actual generation it would involve dragging the mouse across the map overview after clicking some check/radio box that says "Generate mounds" instead.

For the layers UX I'm imagining a tall box for the map height divided by 16 and between every layer of blocks defined (assuming the next layer uses different blocks) the blocks generated will gradually change to the new block within 3 blocks worth of height.

Something like rand_r should be enough for deciding which of the 2 block types to use. Where no block would be generated (top of the mound for instance) checkered tiles should be displayed on the layer box.

Finally on when generating the mound it should have options along the layer box to switch between curving up to the top (hemisphere mode), curving inwards from the top (cave mode), straight (flat mode) and rando overhangs in between (cliff mode).

If you got better ideas for the implementation then go for it, just wanted a better way to generate mountains and the like than creating them by hand.
