ffmpeg | branch: release/4.2 | Marton Balint <cus at passwd.hu> | Tue Aug 13 23:05:44 2019 +0200| [c8dcda22f170a3024c34517a766ff07aa0edaa09] | committer: Marton Balint

ffplay: properly detect all window size changes

SDL_WINDOWEVENT_SIZE_CHANGED should be used instead of SDL_WINDOWEVENT_RESIZED
because SDL_WINDOWEVENT_RESIZED is only emitted if the resize happened due to
an external event.

Fixes ticket #8072.
