Distorted graphics under virgl + qemu

Project Member Reported by lepton@chromium.org, Jul 16 
This is very easily to reproduce.
For example, I am using latest qemu + virgl + epoxy. And just maximuze and minmize chrome window inside qemu, then I got distorted graphics.

I have a video to show this issue:

And more, if seems if I am using virgl code before this commit, I can reproduce it.

I can't reproduce it with this commit.

I think the bug is inside vrend_renderer_blit_int, I just tried to
change use_gl to true inside this function and it also
fixed this issue.

So it seems use_gl==false  code path inside vrend_renderer_blit_int
has some kind of issue.

Actually, we decided not to fix this for now since all of our drivers have GL_(ARB|EXT|OES)_copy_image.  Let me mark this have available.
