Screenshot showing the issue

As the title says, the program doesn't properly refresh after drawing the new
selection, so the old one is still around. Works fine on win7.

According to my tests, it uses LineDDA and SetPixelV to draw these lines.
Also, it's probably only done in WM_MOUSEMOVE. I didn't get a WM_PAINT on
windows while dragging the selection.
