## RESISTANCE
*<resistance><screenEdgeStrength>*
Screen-edge strength is the distance, in pixels, past the edge of a
screen the cursor must move before an interactive move or resize of a
window will continue past the edge. Default is 20 pixels.
*<resistance><screenEdgeStrength>*++
*<resistance><windowEdgeStrength>*
Window-edge strength is the distance, in pixels, past the edge of any
other window the cursor must move before an interactive move or resize
of a window will continue past the edge. Default is 20 pixels.
Resist interactive moves and resizes of a window across screen edges or
the edges of any other window, respectively.
When an edge strength is positive, it indicates a distance, in pixels,
that the cursor must move past any relevant encountered edge before an
interactive move or resize operation will continue across that edge.
When the strength is negative, any interactive move or resize operation
that brings the cursor within the absolute value of the specified
distance, in pixels, from any relevant edge will snap the operation to
that edge. Thus, as a move or resize approaches an edge, it will
"attract" the cursor to that edge within the specified distance. As the
move or resize continues past the edge, it will provide resistance until
the cursor has moved beyond the distance.
A strength of zero disables the corresponding resistance effect.
The default value for both parameters is 20 pixels.
