X Functionality:
Button 1 Zoom with rubberband box
Button 2 Show mouse (x1,x2) coordinates while pressed
q or Q key Quit
s key Save current mouse (x1,x2) location to file
p or P key Plot current window with pswigb (only from disk files)
a or page up keys enhance clipping by 10%
c or page down keys reduce clipping by 10%
up,down,left,right keys move zoom window by half width/height
i or +(keypad) zoom in by factor 2
o or -(keypad) zoom out by factor 2
l lock the zoom while moving the coursor
u unlock the zoom
1,2,...,9 Zoom/Move factor of the window size

Notes:
Reaching the window limits while moving within changes the zoom
factor in this direction. The use of zoom locking(l) disables it

Parameters
		float bias=0.0 data value corresponding to location along axis 2   float clip= data values < bias+clip and > bias-clip are clipped   float d1num=0.0 numbered tic interval on axis 1 (0.0 for automatic)   float d2num=0.0 numbered tic interval on axis 2 (0.0 for automatic)   int endian= endian for display =0 little endian =1 big endian   float f1num=x1min first numbered tic on axis 1 (used if d1num not 0.0)   float f2num=x2min first numbered tic on axis 2 (used if d2num not 0.0)   string grid1= grid lines on axis 1 - none, dot, dash, or solid   string grid2= grid lines on axis 2 - none, dot, dash, or solid   string gridcolor=   int hbox=700 height in pixels of window   bool interp=n [y/n] if y, use interpolation   string label1=   string label2=   string labelcolor=   string labelfont= font name for axes labels   float labelsize=18.0   string mpicks= file to save mouse picks in   int n1tic=1 number of tics per numbered tic on axis 1   int n2tic=1 number of tics per numbered tic on axis 2   float perc=100.0 percentile for determining clip   string style=   string title=   string titlecolor=   string titlefont=   float titlesize=24.0   int va=1 =0 for no variable-area; =1 for variable-area fill; =2 for variable area, solid/grey fill   bool verbose=y [y/n] y for info printed on stderr (n for no info)   int wbox=550 width in pixels of window   int wigclip=0 If 0, the plot box is expanded to accommodate the larger wiggles created by xcur>1. If this flag is non-zero, the extra-large wiggles are are clipped at the boundary of the plot box.   string windowtitle= initialize zoom box parameters   int wt=1 =0 for no wiggle-trace; =1 for wiggle-trace   float x1beg=x1min value at which axis 1 begins   float x1end=x1max value at which axis 1 ends   floats x2= array of sampled values in 2nd dimension [n2]   float x2beg=x2min value at which axis 2 begins   float x2end=x2max value at which axis 2 ends   int xbox=50 x in pixels of upper left corner of window   float xcur=1.0 wiggle excursion in traces corresponding to clip   int ybox=50 y in pixels of upper left corner of window
