Subject: [PATCH] testgles2.c: refresh cached SDL_GL_GetDrawableSize() on
 SDL_WINDOWEVENT_SIZE_CHANGED, not SDL_WINDOWEVENT_RESIZED

Fixes bug with viewport not updating when moving window between monitors with different scale
factors on Windows (this should also fix the same issue on other OS'es, though untested)
