C3D-0265 · 260714 Huckaby: where is the paper vs the border on 17X11 done

READ-ONLY. Reports the printable area and the paper edges in layout coordinates alongside the block and viewport extents, to see exactly how far the border overhangs.

Result

media   : ANSI_B_(17.00_x_11.00_Inches)  rot=Degrees000
paper   : 17.000 x 11.000 in
margins : L0.250 B0.750 R0.250 T0.750 in
PRINTABLE AREA in layout coords: (0.000,0.000) - (16.500,9.500)  = 16.500 x 9.500
   (layout origin 0,0 is the LOWER-LEFT of the PRINTABLE area, not the paper)
   so the paper edges are at x -0.250..16.750, y -0.750..10.250
