Segments
Segments can be manipulated within a BPF.
Activate : to activate a segment, click somewhere between two points and move the mouse a little to have the segment highlighted.
Move : once a segment is selected, it can be moved like a point, with the same
pointer.Gradient : to change the gradient of a segment, move the mouse to display the "resize"
pointer, and scroll the mouse up or down.Delete : to delete a segment, press
Backspace. The two corresponding points of the BPF will disappear.
Do not try to "cut" and paste a segment on another location of the BPF : this would delete the whole BPF.
