Point Capturing

This menu item offers four different options for points:

Automatic: turns point capturing On when the grid or the coordinate axes are shown, and Off when both are hidden.
Snap to Grid: when a point is close enough to an intersection of lines of the grid, it will align to it.
Fixed to Grid: a point can be placed only on the intersections of lines of the grid.
Off: no capturing is applied to the point.

Note: Snap to Grid and Fixed to Grid options, when selected, remain active even though the grid is hidden.
