Calculate wxwidget macros in more logical order (inches first) such that the resulting macros involving inches coordinates are exact integers.
Calculate wxwidget macros in more logical order (inches first) such
that the resulting macros involving inches coordinates are exact integers.

Change the VSCALE macro from 32 to 40 so the maximum coordinate in the
call to plP_setphy is changed from 32*800 = 25600 to 40*800 = 32000.
This improves the wxwidgets resolution by a small but significant
amount without exceeding the maximum valid value for the plP_setphy
call which is 32767.
