From 56ff3647e272b672f8dca8b947bb571ba30d4742 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Mon, 5 Sep 2005 17:18:03 +0000 Subject: I've dithered a bit in the past about whether or not it's allowable to call game_set_size() twice on the same drawstate. Finally, a definite decision: it isn't. Accordingly, midend.c arranges never to do so, the devel docs state that puzzles may enforce by assertion that it never happens, and the four puzzles which care (i.e. use blitters) do so.
