annotate src/main/macosx/SDLMain.m @ 102:9162d62280b5

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't crash if freeing a hardware surface after the video mode has been reset. Fortunately we keep track of the video memory internally.
