Transparency/Ghost visualization of supports

Hi

Sometimes checking supports is hard to do due to the amount of supports blocking the viewport - would be good to have a couple options for visualization.

For example an option to set an overal transparency level for supports would make seeing past them easier.

A better option might be solid tips - all supports are transparent except for the last couple mm`s where it connects with model. Maybe a length setting so we can choose how much of the support is visible?
