Maarten ter Huurne 8a81837c04 Surface: Make pixel format conversion explicit.
Instead of having the copy constructor convert to display format, the new
copy constructor preserves the pixel format and a separate method was
introduced to convert surfaces to display format.

The code was made more robust as well: it should no longer crash if the
wallpaper cannot be loaded.
