Subject: Do a black fade-in when selecting slot.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f0dc1755daeb73522f087185da51d2e9e4058783;p=supertux.git

Do a black fade-in when selecting slot.
To make it really looking good, we would had to have access to the screen. Dunno how we can do this with OpenGL.
