Subject: Draw enemies upside down when falling.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=835fe9710c67ec76af43e74ec601955693924c2a;p=supertux.git

Draw enemies upside down when falling.

The drawing code in texture.cpp is just a hack. Not sure how we can flip surfaces in SDL. The OpenGL should be easily done, I will take care of it later.
