Subject: [PATCH] wmaker: ignore queued motion before the screenshot anchor
 click

imageCaptureArea() consumed any MotionNotify still queued from the
root window before Button1 set the anchor point, with xp,yp still -1
the rectangle math anchored the XOR wireframe at (-1,-1) and drew a
box from the top-left corner to the pointer. Drop motion events
until the press has recorded an anchor.
