Additional features to interactive voxel size adjustment

Adjusting the voxel size for remesh using mouse ( R ) is useful sometimes but also can be a bit finicky other times.

I suggest that capability of invoking manual typing and sampling during the adjustment would improve the workflow.

• Manual typing : Similar to the same feature of the transform tools, typing numbers during adjustment directly input the voxel size. Enter/LMB confirms it.
  • This can be useful when you know the value you want and want to set it quickly.
  • Like the transform tools, typing should disable the ability of adjusting size using mouse, to prevent accidentally changing the value with small mouse movement.

• Sampling : Directly invoke the size sampler/picker that can be accessed from the remesh option panel. Shortcut to invoke the tool should be consistent with other picker tools.
  • Invoking the sampler should disable interactive adjustment status. Confirming or canceling sampling should return to the usual sculpt status. In other words, invoking sampler is practically switching tools.
