Subject: Removed vertical flipping drawing hacks.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f8dcfa6e322b891d4ee1ea96825f86eb897493d6;p=supertux.git

Removed vertical flipping drawing hacks.

Anyway, can we remove the update argument from the drawing functions? It is not used anywhere and OpenGL doesn't support it.
