# HG changeset patch # User Sam Lantinga # Date 1296616783 28800 # Node ID ad50b3db78bdbbc15f7667b656c66d3bf8b6c31d # Parent 3052772b59dbd4ced074a58fa06a916480579f40 The rendering functions take a context so it's clear what window they're drawing to. This also potentially opens to the door to multi-threaded rendering in the future. diff -r 3052772b59db -r ad50b3db78bd include/SDL_render.h --- a/include/SDL_render.h Tue Feb 01 19:15:42 2011 -0800 +++ b/include/SDL_render.h Tue Feb 01 19:19:43 2011 -0800 @@ -86,6 +86,12 @@ } SDL_TextureModulate;
