annotate src/video/gapi/SDL_gapivideo.h @ 4016:3f93ccc2c01e SDL-1.2

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Clear the NOFRAME and RESIZABLE flags in the X11 target before setting their new values, so multiple calls to SetVideoMode() that toggle these will end up with the right data. Fixes Bugzilla #441.
