[GRASS5] [bug #3507] (grass) NVIZ: display degrade after switching desktops II

[Bob Covill]

Hello,

I did find a side effect from the fix below. The togl fly routines were 
using the same callback to draw the coarse mode surface. With the fix 
below this causes the screen to flash as it is trying redraw everything.

I have corrected this in togl_flythrough.c so that in fly mode the 
surface is once again drawn in coarse mode.
