Fix issue 57: Missing refresh in the cross points for the 4-point splines.

Browse Source 
Also fixed the display of the bottom-right corner of the spline itself.
Grad rectangle: The vector line is now drawn as XOR: dragging it no longer erases the screen.
SFont.c: Only removed TAB characters in source.
