This avoid softpipe trying to get image when no window has ever
been exposed, and no image will be exposed.
I'm not entirely sure this is correct or useful, but it definitely
helps with some softpipe get images when we haven't got a window.

Yeah, this looks a little questionable.
Couldn't you add a check for ctx->RasterDiscard in
st_update_framebuffer_state() and no-op most of that function there?
I think you'd at least want to do this after flushing the bitmap and
readpix cache.
