[FEATURE] Re-add ability to "draw" polygons

e.g. hold down left click to draw it as opposed to having to click multiple times

In draw mode, too many points are created to be reasonably corrected, so any mistakes made while drawing require the entire polygon to be deleted. Moreover, an entire object must be traced at once. You can't draw a small part correctly and move onto another part.

In my personal experience, drawing is always more tedious, takes longer, and is generally less accurate than placing points. Could you provide more info about who wants to draw, what their workflow is, and why placing points isn't working for them?

What sort of controls would make drawing less difficult?

Could you provide any examples of annotation tools that allow drawing that you feel work well?

I can toggle it so that way in polygon mode it will turn the hold down to create again, and make sure it doesn't do it in the head/tails or line modes.

I'd prefer not to move toward supporting this feature until a clear user story is formed.

@mattdawkins could you address Brandon's questions above?
