Description
Blockly has a DRAG_RADIUS which makes the blocks a bit "sticky" - unless you move the mouse pointer 5px or more (by default), the block won't start dragging.
My feel of it is that it makes the blocks feel sluggish on touch. Setting it to 1 makes the start of drags feel much nicer. If there's no reason to keep it at > 1, I'll set it to 1.
