Summary: widget.cpp terms fltk console on chang font

Initial Comment:
I'm run FLTK console with user setting of font, or font 
size only, such for sample:
set COLINUX_CONSOLE_FONT=Lucida Console:12

The console is seen with black or white only client area 
and crash with an "invalid memory access".

I found the bug line. It's near
src/colinux/user/console/widget.cpp:169

The line "end = row_start + x2" set the variable "end" to 
memory position behind the buffer "console->screen".

Have added a bug-trace and a workarround.
This was seen at first start:
 end=0x987002 limit=0x987000 row=0x986f60 
start=0x986f60 x1=0 x2=81 y1=0 y2=26

Why is x2 - x1 = 81 here?
That's to big, have only 80 columns!

Henry
