When your form is solid, the OS doesn't have to ask all the windows
below your form to paint themselves to an off-screen buffer and then do
bitblt operations to form a composite image with your form before
painting everything to the screen. When your form is solid, it doesn't
matter what's underneath your form, so only your form gets painted.
