Subject: Managed to update the level editor to the new drawing context code and stuff.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=148cc59583752d131847829535a34ce3ad379e06;p=supertux.git

Managed to update the level editor to the new drawing context code and stuff.
But it has a lot of issues. Scrolling is not being respected, buttons are not working well, and lots of crashing.
Time to rescue the level editor! :)
