Here's one possible solution (I believe):
x_margin = 5 ; Determine these empirically
y_margin = 25
device, get_screen_size=s_size
b = widget_base(xoffset=0, yoffset=0)
d = widget_draw(b, xsize=s_size(0), ysize=s_size(1))
widget_control, b, map=0
widget_control, b, /realize
widget_control, b, tlb_set_xoffset=-x_margin, $
tlb_set_yoffset=-y_margin
widget_control, b, /map
I don't know how you can determine the size of the margins and title
bar that the window system creates for the widget. This information
is not available using WIDGET_CONTROL, WID, /GEOMETRY.
Be aware that if you do this, you will have no way to kill the
widget! Put a "Cancel" button overlaid on the draw widget and
make a simple event handler so you can destroy your widget.
Hope this helps.

Under OpenWindows I once used something like
WINDOW, xsize=800, ysize=600, xpos=-10, ypos=dontknow
and it worked, the window covered the whole screen, the borders lay just
outside.

You can get rid of the title bar, but you can't get rid of the borders.
A window is, after all, a window and there are rules about windows. One
of which is they have borders. The borders can be quite small. This code
on my Windows NT machine gives me a window that is actually 802 by 602.
Function BigWindow, wid
tlb = Widget_Base(TLB_Frame_Attr=4)
drawID = Widget_Draw(tlb, XSize=800, YSize=600)
Widget_Control, tlb, /Realize
Widget_Control, drawID, Get_Value=wid
WSet, wid
Widget_Control, tlb, TLB_GET_SIZE=thisSize
Print, 'Actual window size: ', thisSize
RETURN, tlb
END
widgetID = BigWindow(wid)
TVScl, Dist(800, 600)
Wait, 5
Widget_Control, widgetID, /Destroy
END

No. :-)
