[user] static.c: PaintIcon fix background colour

I've already created a little test program: Windows draws the background 
behind the icon, but not the entire client area. It should be easy to 
modify the existing code.

Your second patch (background for bitmaps in static controls) leaks the 
handle of the brush if GetPixel succeeds.
If GetPixel fails you use the brush returned by SendMessage - but my 
test program shows that Windows doesn't paint the background at all in 
this case.
