Slopes and half blocks of dirt

I would find it very nice if instead of 1 meter jumps I would rather see a more gradual terrain.

- add a half-block of dirt

- alter terrain generation to use them

- could there be a slope block of dirt. It would have to look differently near a corner Vs straight slope.. slopes made of mud would be slippery. Generally a player would ascend or descend on slopes gradually, not like on steps.

Slopes would really smooth out the natural world. On river banks they could sometimes be a slippery mud slope, on meadows half-slopes between half-blocks would have grass.. it would look terrific!

This could add a lot of fun traps and defenses too, letting mobs to slide into a pit, etc

I guess slopes could even be made from sand and gravel, Imagine the dunes or half-slope of gravel in a shallow river.
